• What is a PhD?

Written by Mark Bennett

A PhD is a doctoral research degree and the highest level of academic qualification you can achieve. The degree normally takes between three and four years of full-time work towards a thesis offering an original contribution to your subject.

This page explains what a PhD is, what it involves and what you need to know if you’re considering applying for a PhD research project , or enrolling on a doctoral programme .

On this page

The meaning of a phd.

The PhD can take on something of a mythic status. Are they only for geniuses? Do you have to discover something incredible? Does the qualification make you an academic? And are higher research degrees just for people who want to be academics?

Even the full title, ‘Doctor of Philosophy’, has a somewhat mysterious ring to it. Do you become a doctor? Yes, but not that kind of doctor. Do you have to study Philosophy? No (not unless you want to) .

So, before going any further, let's explain what the term 'PhD' actually means and what defines a doctorate.

What does PhD stand for?

PhD stands for Doctor of Philosophy. This is one of the highest level academic degrees that can be awarded. PhD is an abbreviation of the Latin term (Ph)ilosophiae (D)octor. Traditionally the term ‘philosophy’ does not refer to the subject but its original Greek meaning which roughly translates to ‘lover of wisdom’.

What is a doctorate?

A doctorate is any qualification that awards a doctoral degree. In order to qualify for one you need to produce advanced work that makes a significant new contribution to knowledge in your field. Doing so earns you the title 'Doctor' – hence the name.

So, is a PhD different to a doctorate? No. A PhD is a type of doctorate .

The PhD is the most common type of doctorate and is awarded in almost all subjects at universities around the world. Other doctorates tend to be more specialised or for more practical and professional projects.

Essentially, all PhDs are doctorates, but not all doctorates are PhDs.

Do you need a Masters to get a PhD?

Not necessarily. It's common for students in Arts and the Humanities to complete an MA (Master of Arts) before starting a PhD in order to acquire research experience and techniques. Students in Science, Technology, Engineering and Mathematics (STEM) don't always need an MS/MSc (Master of Science) to do a PhD as you'll gain training in lab techniques and other skills during your undergraduate degree.

Whether a Masters is a requirement for a PhD also varies by country. Australian PhDs may require a Masters as the equivalent of their own 'honours year' (where students work on research). US PhD programmes often include a Masters.

We have a whole guide dedicated to helping you decide whether a PhD without a Masters is the right route for you.

The origin of the PhD

Despite its name, the PhD isn't actually an Ancient Greek degree. Instead it's a much more recent development. The PhD as we know it was developed in nineteenth-century Germany, alongside the modern research university.

Higher education had traditionally focussed on mastery of an existing body of scholarship and the highest academic rank available was, appropriately enough, a Masters degree.

As the focus shifted more onto the production of new knowledge and ideas, the PhD degree was brought in to recognise those who demonstrated the necessary skills and expertise.

The PhD process – what's required to get a PhD?

The typical length of a PhD is three to four years full-time, or five to six years part-time.

Unlike most Masters courses (or all undergraduate programmes), a PhD is a pure research degree. But that doesn’t mean you’ll just spend years locked away in a library or laboratory. In fact, the modern PhD is a diverse and varied qualification with many different components.

Whereas the second or third year of a taught degree look quite a lot like the first (with more modules and coursework at a higher level) a PhD moves through a series of stages.

A typical PhD normally involves:

  • Carrying out a literature review (a survey of current scholarship in your field).
  • Conducting original research and collecting your results .
  • Producing a thesis that presents your conclusions.
  • Writing up your thesis and submitting it as a dissertation .
  • Defending your thesis in an oral viva voce exam.

These stages vary a little between subjects and universities, but they tend to fall into the same sequence over the three years of a typical full-time PhD.

The first year of a PhD

The beginning of a PhD is all about finding your feet as a researcher and getting a solid grounding in the current scholarship that relates to your topic.

You’ll have initial meetings with your supervisor and discuss a plan of action based on your research proposal.

The first step in this will almost certainly be carrying out your literature review . With the guidance of your supervisor you’ll begin surveying and evaluating existing scholarship. This will help situate your research and ensure your work is original.

Your literature review will provide a logical jumping off point for the beginning of your own research and the gathering of results . This could involve designing and implementing experiments, or getting stuck into a pile of primary sources.

The year may end with an MPhil upgrade . This occurs when PhD students are initially registered for an MPhil degree and then ‘upgraded’ to PhD candidates upon making sufficient progress. You’ll submit material from your literature review, or a draft of your research findings and discuss these with members of your department in an upgrade exam . All being well, you’ll then continue with your research as a PhD student.

PhDs in other countries

The information on the page is based on the UK. Most countries follow a similar format, but there are some differences. In the USA , for example, PhD students complete reading assignments and examinations before beginning their research. You can find out more in our guides to PhD study around the world .

The second year of a PhD

Your second year will probably be when you do most of your core research. The process for this will vary depending on your field, but your main focus will be on gathering results from experiments, archival research, surveys or other means.

As your research develops, so will the thesis (or argument) you base upon it. You may even begin writing up chapters or other pieces that will eventually form part of your dissertation .

You’ll still be having regular meetings with your supervisor. They’ll check your progress, provide feedback on your ideas and probably read any drafts your produce.

The second year is also an important stage for your development as a scholar. You’ll be well versed in current research and have begun to collect some important data or develop insights of your own. But you won’t yet be faced with the demanding and time-intensive task of finalising your dissertation.

So, this part of your PhD is a perfect time to think about presenting your work at academic conferences , gaining teaching experience or perhaps even selecting some material for publication in an academic journal. You can read more about these kinds of activities below.

The third year of a PhD

The third year of a PhD is sometimes referred to as the writing up phase.

Traditionally, this is the final part of your doctorate, during which your main task will be pulling together your results and honing your thesis into a dissertation .

In reality, it’s not always as simple as that.

It’s not uncommon for final year PhD students to still be fine-tuning experiments, collecting results or chasing up a few extra sources. This is particularly likely if you spend part of your second year focussing on professional development.

In fact, some students actually take all or part of a fourth year to finalise their dissertation. Whether you are able to do this will depend on the terms of your enrolment – and perhaps your PhD funding .

Eventually though, you are going to be faced with writing up your thesis and submitting your dissertation.

Your supervisor will be very involved in this process. They’ll read through your final draft and let you know when they think your PhD is ready for submission.

All that’s left then is your final viva voce oral exam. This is a formal discussion and defence of your thesis involving at least one internal and external examiner. It’s normally the only assessment procedure for a PhD. Once you’ve passed, you’ve done it!

Doing a PhD – what's it actually like?

You can think of the ‘stages’ outlined above as the basic ‘roadmap’ for a PhD, but the actual ‘journey’ you’ll take as a research student involves a lot of other sights, a few optional destinations and at least one very important fellow passenger.

Carrying out research

Unsurprisingly, you’ll spend most of your time as a PhD researcher… researching your PhD. But this can involve a surprisingly wide range of activities.

The classic image of a student working away in the lab, or sitting with a pile of books in the library is true some of the time – particularly when you’re monitoring experiments or conducting your literature review.

Your PhD can take you much further afield though. You may find yourself visiting archives or facilities to examine their data or look at rare source materials. You could even have the opportunity to spend an extended period ‘in residence’ at a research centre or other institution beyond your university.

Research is also far from being a solitary activity. You’ll have regular discussions with your supervisor (see below) but you may also work with other students from time to time.

This is particularly likely if you’re part of a larger laboratory or workshop group studying the same broad area. But it’s also common to collaborate with students whose projects are more individual. You might work on shorter projects of joint interest, or be part of teams organising events and presentations.

Many universities also run regular internal presentation and discussion groups – a perfect way to get to know other PhD students in your department and offer feedback on each other’s work in progress.

Working with your supervisor

All PhD projects are completed with the guidance of at least one academic supervisor . They will be your main point of contact and support throughout the PhD.

Your supervisor will be an expert in your general area of research, but they won’t have researched on your exact topic before (if they had, your project wouldn’t be original enough for a PhD).

As such, it’s better to think of your supervisor as a mentor, rather than a teacher.

As a PhD student you’re now an independent and original scholar, pushing the boundaries of your field beyond what is currently known (and taught) about it. You’re doing all of this for the first time, of course. But your supervisor isn’t.

They’ll know what’s involved in managing an advanced research project over three years (or more). They’ll know how best to succeed, but they’ll also know what can go wrong and how to spot the warning signs before it does.

Perhaps most importantly, they’ll be someone with the time and expertise to listen to your ideas and help provide feedback and encouragement as you develop your thesis.

Exact supervision arrangements vary between universities and between projects:

  • In Science and Technology projects it’s common for a supervisor to be the lead investigator on a wider research project, with responsibility for a laboratory or workshop that includes several PhD students and other researchers.
  • In Arts and Humanities subjects, a supervisor’s research is more separate from their students’. They may supervise more than one PhD at a time, but each project is essentially separate.

It’s also becoming increasingly common for PhD students to have two (or more) supervisors. The first is usually responsible for guiding your academic research whilst the second is more concerned with the administration of your PhD – ensuring you complete any necessary training and stay on track with your project’s timetable.

However you’re supervised, you’ll have regular meetings to discuss work and check your progress. Your supervisor will also provide feedback on work during your PhD and will play an important role as you near completion: reading your final dissertation draft, helping you select an external examiner and (hopefully) taking you out for a celebratory drink afterwards!

Professional development, networking and communication

Traditionally, the PhD has been viewed as a training process, preparing students for careers in academic research.

As such, it often includes opportunities to pick up additional skills and experiences that are an important part of a scholarly CV. Academics don’t just do research after all. They also teach students, administrate departments – and supervise PhDs.

The modern PhD is also viewed as a more flexible qualification. Not all doctoral graduates end up working in higher education. Many follow alternative careers that are either related to their subject of specialism or draw upon the advanced research skills their PhD has developed.

PhD programmes have begun to reflect this. Many now emphasise transferrable skills or include specific training units designed to help students communicate and apply their research beyond the university.

What all of this means is that very few PhD experiences are just about researching and writing up a thesis.

The likelihood is that you’ll also do some (or all) of the following during your PhD:

The work is usually paid and is increasingly accompanied by formal training and evaluation.

Conference presentation

As a PhD student you’ll be at the cutting edge of your field, doing original research and producing new results. This means that your work will be interest to other scholars and that your results could be worth presenting at academic conferences .

Doing this is very worthwhile, whatever your career plans. You’ll develop transferrable skills in public speaking and presenting, gain feedback on your results and begin to be recognised as an expert in your area.

Conferences are also great places to network with other students and academics.

Publication

As well as presenting your research, you may also have the opportunity to publish work in academic journals, books, or other media. This can be a challenging process.

Your work will be judged according to the same high standards as any other scholar’s and will normally go through extensive peer review processes. But it’s also highly rewarding. Seeing your work ‘in print’ is an incredible validation of your PhD research and a definite boost to your academic CV.

Public engagement and communication

Academic work may be associated with the myth of the ‘ivory tower’ – an insular community of experts focussing on obscure topics of little interest outside the university. But this is far from the case. More and more emphasis is being placed on the ‘impact’ of research and its wider benefits to the public – with funding decisions being made accordingly.

Thankfully, there are plenty of opportunities to try your hand at public engagement as a PhD student. Universities are often involved in local events and initiatives to communicate the benefits of their research, ranging from workshops in local schools to public lectures and presentations.

Some PhD programmes include structured training in order to help students with activities such as the above. Your supervisor may also be able to help by identifying suitable conferences and public engagement opportunities, or by involving you in appropriate university events and public engagement initiatives.

These experiences will be an important part of your development as a researchers - and will enhance the value of your PhD regardless of your career plans.

What is a PhD for – and who should study one?

So, you know what a PhD actually is, what’s involved in completing one and what you might get up to whilst you do. That just leaves one final question: should you do a PhD?

Unfortunately, it’s not a question we can answer for you.

A PhD is difficult and uniquely challenging. It requires at least three years of hard work and dedication after you’ve already completed an undergraduate degree (and probably a Masters degree too).

You’ll need to support yourself during those years and, whilst you will be building up an impressive set of skills, you won’t be directly progressing in a career.

But a PhD is also immensely rewarding. It’s your chance to make a genuine contribution to the sum of human knowledge and produce work that other researchers can (and will) build on in future. However obscure your topic feels, there’s really no such thing as a useless PhD.

A PhD is also something to be incredibly proud of. A proportionately tiny number of people go on to do academic work at this level. Whatever you end up doing after your doctorate you’ll have an impressive qualification – and a title to match. What’s more, non-academic careers and professions are increasingly recognising the unique skills and experience a PhD brings.

Other PhDs - do degree titles matter?

The PhD is the oldest and most common form of higher research degree, but a few alternatives are available. Some, such as the DPhil are essentially identical to a PhD. Others, such as the Professional Doctorate or DBA are slightly different. You can find out more in our guide to types of PhD .

Is a PhD for me?

There’s more advice on the value of a PhD – and good reasons for studying one – elsewhere in this section. But the following are some quick tips if you’re just beginning to consider a PhD.

Speak to your lecturers / tutors

The best people to ask about PhD study are people who’ve earned one. Ask staff at your current or previous university about their experience of doctoral research – what they enjoyed, what they didn’t and what their tips might be.

If you’re considering a PhD for an academic career, ask about that too. Are job prospects good in your field? And what’s it really like to work at a university?

Speak to current PhD students

Want to know what it’s like studying a PhD right now? Or what it’s like doing research at a particular university? Ask someone who knows.

Current PhD students were just like you a year or two ago and most will be happy to answer questions.

If you can’t get in touch with any students ‘face to face’, pop over to the Postgraduate Forum – you’ll find plenty of students there who are happy to chat about postgraduate research.

Take a look at advertised projects and programmes

This may seem like a strange suggestion. After all, you’re only going to study one PhD, so what’s the point of reading about lots of others?

Well, looking at the details of different PhD projects is a great way to get a general sense of what PhD research is like. You’ll see what different PhDs tend to have in common and what kinds of unique opportunity might be available to you.

And, with thousands of PhDs in our database , you’re already in a great place to start.

What is a PhD? Advice for PhD students

How long does it take to get a doctorate degree how do you get into grad school are you qualified to do a phd answers to these questions and more.

PhD, doctorate

What is a PhD?

A PhD, which stands for “doctor of philosophy”, is the most advanced academic degree. It’s earned through extensive research on a specific topic, demonstrating expertise and contributing new knowledge to the field.

What does “PhD” mean?

The term “PhD” is often used as a synonym for any doctoral-level qualification. Doctorate degrees can often be split into two categories: MPhil and PhD.

Free study abroad guide

Download your Study Abroad Guide for FREE!

An MPhil is similar to a PhD as it includes a research element (which is usually shorter and less in-depth than a PhD thesis, and often more akin to a dissertation undertaken at undergraduate or master’s level). 

MPhil students focus more on interpreting existing knowledge and theory and critically evaluating other people’s work rather than producing their own research. The precise nature and definition of an MPhil can vary among institutions and countries. 

A PhD, meanwhile, follows a more widely known and traditional route and requires students, often referred to as “candidates”, to produce their own work and research on a new area or topic to a high academic standard.

PhD requirements vary significantly among countries and institutions. The PhD, once completed, grants the successful candidate the title of “doctor of philosophy”, also called PhD or DPhil.

What is a professional doctorate?

A professional doctorate is a kind of degree that helps people become experts in their fields. Instead of focusing mainly on theory and research like a regular PhD, a professional doctorate is all about practical skills and knowledge.

This kind of doctorate is great for students who want to get better at their jobs in areas like teaching, healthcare, business, law or psychology. The courses and projects in these programmes are designed to tackle real problems you might face at work.

For example, you might have heard of the doctor of education (EdD), doctor of business administration (DBA), doctor of psychology (PsyD) or doctor of nursing practice (DNP). These programmes combine learning, hands-on projects and sometimes a thesis paper or essay to show you’re skilled at solving on-the-job challenges.

How long does it take to study a PhD?

The time required to complete a PhD can vary significantly based on several factors. Generally, a full-time PhD programme takes around three to six years to finish. However, it’s important to take into account individual circumstances and the nature of the research involved.

1. Full-time vs. part-time: If you’re studying full-time, dedicating most of your time to your studies, it usually takes about three to four years to complete a PhD. However, studying part-time while managing other commitments might extend the duration. Part-time PhDs can take around six to eight years, and sometimes even longer.

2. Nature of research: The complexity of your research proposal can influence the time required. Certain research questions may involve intricate experiments, extensive data collection or in-depth analysis, potentially leading to a longer completion timeline.

3. Field of study: The subject area you’re researching can also affect the necessary time. Some fields, such as sciences or engineering, might involve more hands-on work, while theoretical subjects might require more time for literature review and analysis.

4. Supervision and support: The guidance and availability of your academic supervisor can affect the pace of your research progress. Regular meetings and effective communication can help keep your studies on track.

5. Thesis writing: While the research phase is crucial, the stage of writing your thesis is equally significant. Organising and presenting your research findings in a clear and cohesive manner can take several months.

6. External commitments: Personal commitments, such as work, family or health-related factors, can influence your study time. Some students need to balance these alongside their PhD studies, potentially extending the duration.

7. External Funding: The availability of funding can also affect your study duration. Some funding might be linked to specific project timelines or research objectives.

So, although a PhD usually takes between three and six years of full-time study, with potential variations based on research complexity, enrolment as part-time or full-time, field of study and personal circumstances. It’s vital to have a realistic understanding of these factors when planning your PhD journey.

How long is a PhD in the UK?

In the UK, the length of a PhD programme typically ranges from three to four years of full-time study. As explained above, there are many factors to consider.

How long is a PhD in the US?

Similarly to the UK, in the United States, the duration of a PhD programme can vary widely depending on the field of study, research topic and individual circumstances. On average, a full-time PhD programme in the US typically takes between five and six years to complete.

Why does it take longer to study a PhD in the US?

PhD programmes generally take longer to complete in the US than in the UK due to various factors in the education systems and programme structures of each country:

1. Programme structure: UK PhD programmes often emphasise early, focused research from the first year, leading to shorter completion times. In contrast, US programmes commonly include more initial coursework in your first and second year and broader foundational training, which can extend the overall duration.

2. Course work requirements: Many US PhD programmes require a lot of course work, which can lengthen the time needed to finish. UK programmes tend to have fewer or no course work demands, allowing students to concentrate primarily on research skills.

3. Research funding: In the UK, PhD funding is often awarded with specific timeframes in mind, motivating completion of the research degree in the agreed duration. In the US, funding approaches can vary, requiring students to secure funding from multiple sources, potentially affecting their progress and completion time.

4. Teaching responsibilities: Some US PhD students take on teaching roles as part of their funding, dividing their time and potentially prolonging their studies.

5. Research approach: Differences in research methodologies and project scopes can affect the time needed for data collection, experimentation and analysis.

6. Academic culture: The US education system values a well-rounded education, including coursework and comprehensive exams. This can extend the time before full-time research begins. UK PhD programmes often prioritise independent research early on.

7. Part-time and work commitments: US PhD candidates might have more flexibility for part-time work or other commitments, which can affect research progress.

8. Dissertation requirements: US PhD programmes generally include a longer and more comprehensive dissertation, involving more chapters and a broader exploration of the research topic.

These variations in programme structures, funding models and academic cultures contribute to the differing completion times between the two countries.

What qualifications do you need for a PhD?

To be eligible for a PhD programme, certain educational qualifications are generally expected by universities. These qualifications serve as indicators of your readiness to engage in advanced research and contribute to the academic community.

First, an undergraduate or bachelor’s degree in a relevant field is typically the most common requirement. This degree provides you with a foundational understanding of the subject and introduces you to basic research methodologies. It serves as a starting point for your academic journey.

Do you need a master’s degree to get into a PhD programme?

In addition to an undergraduate degree, many PhD programmes also require candidates to hold postgraduate or master’s degrees, often in fields related to the intended PhD research. A master’s degree offers a deeper exploration of the subject matter and enhances your research skills. Possessing a master’s degree signifies a higher level of expertise and specialisation.

The combination of both undergraduate and postgraduate degrees demonstrates a solid academic background. This background is crucial before you engage in doctoral study because pursuing a PhD involves more than just knowledge; it requires advanced research abilities, critical thinking and the capacity to provide an original contribution and new insights into the chosen field of study.

While these qualifications are usually requested, there are exceptions. Some institutions offer direct-entry programmes that encompass bachelor’s, master’s and PhD degrees in a streamlined structure. This approach is often seen in scientific and engineering disciplines rather than humanities.

In exceptional cases, outstanding performance during undergraduate studies, coupled with a well-defined research proposal, might lead to direct entry into a PhD programme without requiring a master’s degree.

Admission requirements can vary between universities and programmes. Some institutions might have more flexible prerequisites, while others could have more stringent criteria. Make sure that you thoroughly research all admission requirements of the PhD programmes you’re interested in to ensure you provide the right information.

Are PhD entry requirements similar in other countries?

PhD entry requirements in Canada and Australia can be somewhat similar to those in the UK and the US, but there are also some differences. Just like in the UK and the US, having a bachelor’s degree followed by a master’s degree is a common way to qualify for a PhD in Canada and Australia. However, the exact rules can vary, such as how much research experience you need or the grades you should have.

In Canada and Australia, as in the UK and the US, international students usually need to show their English language skills through tests like IELTS or TOEFL. And, like in other places, you might need to give a research proposal to explain what you want to study for your PhD.

But remember, even though there are some similarities, each country has its own rules.

How much does it cost to study a PhD?

The cost of pursuing a PhD can vary significantly between international and home (domestic) students, and it depends on the country, university and programme you choose.

United Kingdom (UK)

Home students in the UK often pay lower tuition fees compared with international students. Home students might also have access to government funding or subsidised tuition rates.

International students typically pay higher tuition fees, which can vary widely depending on the university and programme. Fees can range from around £10,000 to £25,000 or more per year.

United States (US)

PhD programme costs in the US can be quite high, especially for international students. Public universities often have lower tuition rates for in-state residents compared with out-of-state residents and international students.

Private universities in the US generally have higher tuition fees, and international students might be charged higher rates than domestic students.

Canadian universities often charge higher tuition fees for international students compared with domestic students.

Some universities offer funding packages that include tuition waivers and stipends for both domestic and international doctoral students.

In Australia, domestic students (Australian citizens and permanent residents) usually pay lower tuition fees than international students.

International students in Australia might have higher tuition fees, and costs can vary based on the university and programme.

Apart from tuition fees, other aspects play a role in the overall financial consideration:

PhD studentship: Many universities offer PhD studentships that provide financial support to research students, covering both tuition fees and a stipend for living expenses.

Stipend and housing: Stipends are designed to cover living expenses. Stipend amounts can vary depending on the university and location. If you’re studying in London in the UK, stipends might be higher to account for the higher living costs in the city. Some universities also offer subsidised or affordable housing options for doctoral students.

Tuition and stipend packages: Some PhD programmes provide funding packages that include both tuition waivers and stipends. These packages are to help relieve the financial burden on students during their doctoral studies.

Research the financial support options provided by the universities you’re interested in to make an informed decision about the cost of your PhD journey.

What funding options are available for PhD candidates?

PhD candidates have various funding options available to support their studies and research journeys. Some of these options include:

PhD scholarships: Scholarships are a common form of financial aid for PhD candidates. They are awarded based on academic merit, research potential or other specific criteria. Scholarships can cover tuition fees and provide a stipend for living expenses.

Bursaries: Bursaries are another form of financial assistance offered to students, including PhD candidates, based on financial need. They can help cover tuition fees or provide additional financial support.

In the UK, specific funding options are available:

Regional consortium: Some regions have research consortiums that offer funding opportunities for doctoral candidates. These collaborations can provide financial support for research projects aligned with specific regional needs.

UK research institute: Research councils in the UK often offer stipends to PhD candidates. These stipends cover living expenses and support research work.

University-based studentship: Many UK universities offer studentships. You can read more about these above.

In the USA, there are also funding options available:

Research assistantships (RAs): Many universities offer research assistantships where PhD candidates work on research projects under the guidance of faculty members. In exchange, they receive stipends and often have their tuition waived.

Teaching assistantships (TA): Teaching assistantships involve assisting professors in teaching undergraduate courses. In return, PhD candidates receive stipends and sometimes tuition remission.

Fellowships: Fellowships are competitive awards that provide financial support for PhD candidates. They can come from universities, government agencies, private foundations and other institutions. Fellowships can cover tuition, provide stipends and offer research or travel funds.

Graduate assistantships: Graduate assistantships include a range of roles, from research and teaching to administrative support. These positions often come with stipends and sometimes include tuition benefits.

External grants and fellowships: PhD candidates can apply for grants and fellowships from external organisations and foundations that support research careers in specific fields. Examples include the National Science Foundation (NSF) and the Fulbright Programme.

Employer sponsorship: In some cases, employers might sponsor employees to pursue PhDs, especially if the research aligns with the company’s interests.

What does a PhD Involve?

How does a PhD work?

A PhD includes thorough academic research and significant contributions to your chosen field of study. The timeline for completing a PhD can significantly vary based on the country, college or university you attend and the specific subject you study.

The duration of a PhD programme can vary based on factors such as the institution’s requirements and the academic discipline you’re pursuing. For instance, the timeline for a PhD in a science-related field might differ from that of a humanities discipline.

UK PhD timeline example

Looking at a typical PhD degree in a London higher education institution, we can consider this example timeline.

In the initial year of your PhD, you’ll collaborate closely with your designated academic supervisor. This collaboration involves refining and solidifying your research proposal, which lays the foundation for your entire doctoral journey.

This is also the time to establish a comprehensive plan, complete with well-defined milestones and deadlines. A crucial aspect of this year is conducting an extensive literature review, immersing yourself in existing academic works to understand the landscape of your chosen research area. It’s important to make sure that your research idea is original and distinct from prior studies.

As you begin the second year, you’ll actively collect data and gather information related to your research topic. Simultaneously, you’ll initiate the process of crafting your thesis. This involves combining your research findings and analysis into sections of your thesis document.

This is also the phase where you might have opportunities to share your research insights at academic meetings, conferences or workshops. Depending on the programme, you might even engage in teaching activities. Some PhD candidates also begin contributing to academic journals or books, showcasing their findings to a broader audience.

The third year of a PhD programme often marks the final stage of your research efforts. This is when you dedicate substantial time to writing and finalising your complete thesis. Once your thesis is completed to the highest standard, you’ll submit it for thorough evaluation.

A significant milestone in the third year is the viva voce, an oral examination where you’ll defend your thesis before a panel of experts in your field. The viva voce is an opportunity to showcase your deep understanding of your research and defend your findings.

Why should you do a PhD?

For many people, acquiring a doctorate degree is the pinnacle of academic achievement, the culmination of years of commitment to higher education.

However, the act of pursuing a PhD can be a complex, frustrating, expensive and time-consuming exercise. But with the right preparation, some sound advice and a thorough understanding of the task at hand, your years as a doctoral student can be some of the most rewarding of your life. 

People choose to work towards a doctorate for many reasons. If you are looking to pursue an academic position, such as university lecturer or researcher, then a PhD is usually required.

Many people obtain a PhD as part of a partnership with an employer, particularly in scientific fields such as engineering, where their research can prove useful for companies.

In some cases, however, PhDs are simply down to an individual’s love of a subject and their desire to learn more about their field.

What are some benefits of studying a PhD?

Pursuing a PhD can have many benefits that extend beyond academic achievement, encompassing personal growth, professional advancement and meaningful contributions to knowledge.

One of the most notable benefits of a PhD is the potential for tenure in academia. Attaining tenure provides a level of job security that allows you to delve into long-term research projects and make enduring contributions to your field. It signifies a stage where you can explore innovative ideas and pursue in-depth research, fostering your academic legacy.

While not obligatory, the opportunity to collaborate on research projects with your supervisor is another valuable aspect of a PhD pursuit. These collaborations might even come with financial compensation, offering real-world experience, skill development and practical applications of your research. Engaging in such collaborations can enrich your research portfolio and refine your research methodologies.

A pivotal aspect of a PhD journey is the chance to publish your original research findings. By disseminating your work in academic journals or presenting it at conferences, you contribute to the expansion of knowledge within your field. These publications establish your expertise and reputation among peers and researchers worldwide, leaving a lasting impact.

The pursuit of a PhD can provide a unique platform to build a diverse network of colleagues, mentors and collaborators. Engaging with fellow researchers, attending conferences and participating in academic events offer opportunities to make valuable connections. This network can lead to collaborations, expose you to a spectrum of perspectives and pave the way for future research endeavours.

What is a PhD thesis? And what is a PhD viva?

A PhD thesis will be produced with help from an academic supervisor, usually one with expertise in your particular field of study. This thesis is the backbone of a PhD, and is the candidate’s opportunity to communicate their original research to others in their field (and a wider audience).  PhD students also have to explain their research project and defend their thesis in front of a panel of academics. This part of the process is often the most challenging, since writing a thesis is a major part of many undergraduate or master’s degrees, but having to defend it from criticism in real time is arguably more daunting.  This questioning is known as a “viva”, and examiners will pay particular attention to a PhD’s weaknesses either in terms of methodology or findings. Candidates will be expected to have a strong understanding of their subject areas and be able to justify specific elements of their research quickly and succinctly.

In rare cases, students going for a PhD may instead be awarded an MPhil if the academic standard of their work is not considered fully up to par but still strong enough to be deserving of a qualification.

Can you do a PhD part time? 

Many PhD and MPhil candidates choose to pursue their qualification part time, in order to allow time to work and earn while studying. This is especially true of older students, who might be returning to academia after working for a few years. 

When applying, you should always speak to the admissions team at your university to ensure this is possible and then continue to work with your supervisor to balance all your commitments. 

Can I do a PhD through distance learning?

This is something else that you will need to check with your university. Some institutions offer this option, depending on the nature of your research. 

You will need to be clear how many times you will need to travel to your university to meet with your supervisor throughout your PhD. 

Your PhD supervisor

Choosing the right PhD supervisor is essential if you want to get the most out of your PhD. Do your research into the faculty at the institution and ensure that you meet with your proposed supervisor (either virtually or in person) before fully committing. 

You need to know that not only do they have the right expertise and understanding of your research but also that your personalities won’t clash throughout your PhD. 

Remember, to complete your PhD, you will need a strong support network in place, and your supervisor is a key part of that network. 

Coping with PhD stress

If you do decide to embark on a doctorate, you may well encounter stress and anxiety. The work involved is often carried out alone, the hours can be long and many students can suffer from the pressure they feel is on their shoulders.

Ensuring that you check in regularly with your emotions and your workload is crucial to avoid burnout. If you have other commitments, such as a job or a family, then learning to balance these can feel overwhelming at times. 

Give yourself regular breaks, speak to your supervisor and ensure that you know what university resources and support systems are available to you in case you need to access them. 

Post-doctorate: what happens after you finish your PhD?

Many PhD graduates pursue a career in academia, while others will work in industry. Some might take time out, if they can afford to, to recover from the efforts of PhD study.

Whatever you choose to do, undertaking a PhD is a huge task that can open up a range of doors professionally. Just remember to take some time out to celebrate your achievement. 

How does a PhD affect salary and earning potential?

How much does a professor with a PhD make a year?

Professors with PhDs can earn different amounts depending on where they work and their experience. In the UK, a professor might make around £50,000 to £100,000 or more each year. In the US, it's between about $60,000 and $200,000 or even higher. The exact salary depends on things like the place they work, if they have tenure, and what they teach.

How much does a PhD add to salary?

Having a PhD can make your salary higher than if you had a lower degree. But exactly how much more you earn can change. On average, people with PhDs earn more than those with bachelor’s or master’s degrees. The increase in salary is influenced by many things, such as the job you do, where you work and what field you’re in.

In fields such as research, healthcare, technology and finance, your knowledge and skills from your PhD can potentially help you secure a higher salary position.

In the end, having a PhD can boost your earning potential and open doors to well-paying jobs, including professorships and special roles in different areas. But the exact effect on your salary is influenced by many things, so ensure you weigh the cost against the benefit.

How to choose a PhD programme?

Choosing a PhD programme involves defining your research interest, researching supervisors and programme reputation, evaluating funding options, reviewing programme structure, considering available resources, assessing networking opportunities, factoring in location and career outcomes, visiting the campus if possible and trusting your instincts.

What is a PhD?

  • Types of Doctorates
  • A Doctor of Philosophy (PhD) is the highest globally recognized postgraduate degree that higher education institutions can award.
  • PhDs are awarded to candidates who undertake original and extensive research in a particular field of study.
  • Full time PhD programmes typically last three to four years, whilst part time PhD programmes typically last six to seven years.
  • A PhD can lead to an academia teaching role or a career in research. A PhD can also equip you with skills suitable for a wide range of jobs unrelated to your research topic or academia.

Definition of a PhD – A Doctor of Philosophy (commonly abbreviated to PhD , Ph.D or a DPhil ) is a university research degree awarded from across a broad range of academic disciplines; in most countries, it is a terminal degree, i.e. the highest academic degree possible.

PhDs differ from undergraduate and master’s degrees in that PhDs are entirely research-based rather than involving taught modules (although doctoral training centres (DTCs) offer programmes that start with a year of lecture-based teaching to help develop your research skills prior to starting your project).

In most English-speaking countries, those that complete a PhD use the title “Doctor” (typically abbreviated to Dr) in front of their names and are referred to as such within academic and/or research settings. Those that work in fields outside of academia may decide not to use the formal doctor title but use post-nominal letters (e.g. John Smith PhD); it’s unusual though for someone to use both the Doctor title and post-nominal letters in their name.

PhD vs Doctorate

A PhD and a professional doctorate are both research-based terminal degrees.

However, where a PhD focuses on original research mostly around theoretical concepts, a professional doctorate focuses on examining existing knowledge to solve real-life, practical problems.

While there is much crossover between the two, a PhD is generally better suited for an individual to wants to advance the knowledge and understanding in their field, and a professional doctorate degree is better suited to a working professional who wants to better be able to apply knowledge and understanding to their field.

What Are the Entry Requirements for a PhD?

To be accepted on to a PhD programme, students usually need to hold at least a high ( 2:1 and above ) undergraduate degree that is related to the field of research that they want to pursue. A PhD candidate may also be expected to hold a Master’s degree , however, this does not mean you must have one, as it is still possible to enrol into a PhD without a Master’s .

Self-funded courses may sometimes be more relaxed in relation to entry requirements . It may be possible to be accepted onto a self-funded PhD programme with lower grades, though these students typically demonstrate their suitability for the role through professional work experience.

Whilst a distance learning project is possible , most PhD candidates will carry out their research over at least three years based at their university, with regular contact with two academic supervisors (primary and secondary). This is particularly the case for lab-based projects, however, some PhD projects require spending time on-site away from university (e.g. at a specialist research lab or at a collaborating institution abroad).

How Long Does a PhD Take?

Typically, full-time PhDs last 3-4 years and part-time PhDs last 6-7 years. However, at the discretion of the university, the thesis writing-up period can be extended by up to four years.

Although most doctoral programmes start in September or October, they are generally much more flexible than taught-courses and can start at any time of the year.

How Much Does a PhD Cost?

Tuition fees for UK and EU students vary between £3,000 and £6,000 per year, with the average tuition fee of £4,712 per year for 2023/24 programmes.

Tuition fees increase considerably for international students, varying between £16,000 to £25,000 per year, with an average tuition fee of £19,600 per year .

Nonetheless, most students will secure PhD funding in the form of studentships, scholarships and bursaries to help pay for these fees. These funding opportunities can either be partial, which cover tuition fees only, or full, which cover both tuition fees and living expenses.

UK national students can also apply for Doctoral Loans from Student Finance England if they are unable to secure funding.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What Does a PhD Involve?

To be awarded a PhD, a doctoral student is required to produce a substantial body of work that adds new knowledge to their chosen field.

A PhD programme will typically involve four key stages:

Stage 1: Literature Review

The first year of a PhD involves attending regular meetings with your supervisors and carrying out a search on previously published work in your subject area. This search will be used to produce a literature review which should set the context of the project by explaining the foundation of what is currently known within the field of research, what recent developments have occurred, and where the gaps in knowledge are. In most cases, this will be an extension of your research proposal should you have produced one as part of your application. The literature review should conclude by outlining the overarching aims and objectives of the research project. This stage of setting achievable goals which are original and contribute to the field of research is an essential first step in a successful PhD.

The supervisor is the main point of contact through the duration of a PhD – but remember: they are there to mentor, not to teach, or do it for you . It will be your responsibility to plan, execute and monitor your own work as well as to identify gaps in your own knowledge and address them.

Stage 2: Research

The second year (and prehapse some of your third year) is when you work on your research. Having identified novel research questions from your review of the literature, this is where you collect your data to help answer these questions. How you do this will depend on the nature of your doctoral research: for example, you may design and run experiments in a lab alongside other PhD students or visit excavation sites in remote regions of the world. You should check in regularly with your supervisors to update them and run any ideas or issues past them.

Have the structure and chapters of your thesis in mind as you develop and tackle your research questions. Working with a view of publishing your work will be very valuable later on.

Stage 3: Write up of Thesis

The next key stage of a PhD is writing a doctoral thesis , which typically takes from anywhere between three months to one year. A thesis is a substantial body of work that describes the work and outcomes of the research over the previous two to three years. It should tell a detailed story of the PhD project – focusing on:

  • The motivations for the research questions identified from the literature review.
  • The methodologies used, results obtained, and a comprehensive analysis and discussion of the findings.
  • A detailed discussion of the key findings with an emphasis on the original contributions made to your field of research and how this has been impactful.

There is no universal rule for the length of a PhD thesis, but general guidelines set the word count between 80,000 to 100,000 words.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available.

Stage 4: Attending the Viva

A viva voce , most commonly referred to as just a ‘ viva ‘, is an interview-style examination where the PhD student is required to engage in a critical appraisal of their work and defend their thesis against at least two examiners. The examiners will ask questions to check the PhD student has an in-depth understanding of the ideas and theories proposed in their thesis, and whether they have developed the research skills that would be expected of them.

The viva is one of the final steps in achieving a PhD, and typically lasts at least two hours, but this duration can vary depending on the examiners, the university and the PhD project itself.

Once you have done the viva – you’re on the home stretch. You will typically be asked to make some amendments to your thesis based on the examiner’s feedback. You are then ready to submit your final thesis for either:

  • PhD – If you pass the requirements you will be awarded a PhD degree (most common outcome),
  • MPhil – If you failed to meet requirements for a PhD, you may be downgraded to an MPhil degree (uncommon outcome),
  • Fail – No award is given, typically for cases of plagiarism (extremely uncommon outcome).

What Is It Like to Undertake a PhD?

We’re often asked what it is like to undertake a PhD study. Unfortunately, this isn’t a simple answer to this question as every research project is different.

To help give insight into the life of a PhD student, we’ve interviewed PhD students at various stages of their programmes and put together a series of PhD Student Interviews . Check out the link to find out what a PhD is like and what advice they have to offer you.

What Are the Benefits of A PhD?

A PhD is the highest globally recognised postgraduate degree that higher education institutions can award. The degree, which is awarded to candidates who demonstrate original and independent research in a particular field of study, is not only invaluable in itself, but sets you up with invaluable skills and traits.

Career Opportunities

First, a PhD prepares you for a career in academia if you wish to continue in this area. This takes form as a career in the Higher Education sector, typically as a lecturer working their way to becoming a professor leading research on the subject you’ve studied and trained in.

Second, a PhD also enables the opportunity for landing a job in a research & development role outside of the academic environment. Examples of this include laboratory work for a private or third sector company, a governmental role and research for commercial and industrial applications.

Transferable Skills

Finally, in possessing a PhD degree, you can show to employers that you have vital skills that make you an asset to any company. Three examples of the transferable skills that you gain through a PhD are effective communication, time management, and report writing.

  • Communication – presenting your work in written and oral forms using journal papers and podium presentations, shows your ability to share complex ideas effectively and to those with less background knowledge than you. Communication is key in the professional environment, regardless of the job.
  • Time management – The ability to prioritise and organise tasks is a tremendous asset in the professional industry. A PhD holder can use their qualification to demonstrate that they are able to manage their time, arrange and follow a plan, and stick to deadlines.
  • Report writing – Condensing three years of work into a thesis demonstrates your ability to filter through massive amounts of information, identify the key points, and get these points across to the reader. The ability to ‘cut out the waffle’ or ‘get to the point’ is a huge asset in the professional industry.

Aside from the above, you also get to refer to yourself as a Doctor and add fancy initials after your name!

What Can I Do After a PhD?

One of the most desirable postdoctoral fields is working within independent Research and Development (R&D) labs and new emerging companies. Both industries, especially R&D labs, have dedicated groups of PhD graduates who lead research activities, design new products and take part in crucial strategic meetings. Not only is this a stimulating line of work, but the average salaries in R&D labs and emerging start-ups are lucrative. In comparison, an undergraduate with five years of experience within their given field will, on average, likely earn less than a new PhD graduate taking on a R&D position.

It’s a common misunderstanding that PhDs only opens the door for an academic career such as university lecturers and training providers. Although obtaining a PhD opens these doors, the opportunities extend far beyond educational roles. In fact, recent data from the UK’s Higher Education Statistics Agency (HESA) indicates only 23% of PhD graduates take a position in educational roles . This low percentage is primarily because PhD graduates have a wide range of skills that make them suitable for a broad spectrum of roles. This is being seen first hand by the increasing number of PhD graduates who are entering alternative roles such as research, writing, law and investment banking.

How Do I Find a PhD?

We appreciate that finding a PhD programme to undertake can be a relatively daunting process. According to Higher Education Student Statistics , over 22,000 PhDs were awarded in 2016/17 within the United Kingdom alone. Clearly there are a huge number of PhD programmes available. This can sometimes be confusing for prospective doctorates, particularly when different programmes are advertised in different places. Often, it is difficult to know where to look or where to even start. We’ve put together a list of useful sources to find the latest PhD programmes:

  • A great place to start is with our comprehensive and up-to-date database of available PhD positions .
  • Assuming you are still at university, speak to an existing PhD supervisor within your department.
  • Attend as many postgraduate open days as you can. Whilst there, speak to current PhD students and career advisors to get an awareness of what PhDs are on offer.
  • Visit the postgraduate section of university websites and the PhD Research Council section of the UKRI website.

What is a PhD?

As the highest degree level achievable, completing a PhD shows that you've made a meaningful new contribution to your research field

PhDs at a glance

  • Involves three or four years of full-time study, or up to seven part time.
  • Typically undertaken after achieving a Masters degree.
  • Can either be funded or self-funded.
  • Assessed through a written thesis and oral exam.
  • Many Doctoral graduates choose to pursue an academic or research career.

What does PhD stand for?

The term PhD or Doctorate of Philosophy is an abbreviation of the Latin phrase 'philosophiae doctor'.

A PhD degree typically involves students independently conducting original and significant research in a specific field or subject, before producing a publication-worthy thesis.

While some Doctorates include taught components, PhD students are almost always assessed on the quality and originality of the argument presented in their independent research project.

What are the most popular PhD subjects?

  • clinical psychology
  • creative writing
  • computer science
  • engineering.

How long does a Doctorate degree take?

Full-time PhDs usually last for three or four years, while part-time PhDs can take up to six or seven. However, the thesis deadline can be extended by up to four years at the institution's discretion. Indeed, many students who enrol on three-year PhDs only finish their thesis in their fourth year.

While most PhD studentships begin in September or October, both funded and self-funded PhDs can be undertaken at any point during the year.

Do I need a Masters to do a PhD?

The majority of institutions require PhD candidates to possess a Masters degree , plus a Bachelors degree at 2:1 or above. However, some universities demand only the latter, while self-funded PhD students or those with significant professional experience may also be accepted with lower grades.

You may need to initially register for a one or two-year Master of Philosophy (MPhil) or Master of Research (MRes) degree rather than a PhD. If you make sufficient progress, you and your work will then be 'upgraded' to a PhD programme. If not, you may be able to graduate with a Masters degree.

If you need an MPhil or MRes before enrolling on your PhD, search Masters degrees .

What does a PhD involve?

A standard PhD by thesis degree is typically split into three stages. A three-year PhD may follow this pattern:

  • First year - You'll meet with your supervisor to discuss your research proposal and agree an action plan with deadlines. You'll then complete your literature review, in which you'll evaluate and critique existing works to inform the direction of your project and ensure that your research will be original.
  • Second year - Your focus will shift to gathering results and developing your thesis, and potentially begin writing chapters of your thesis. You may also present your results and ideas at academic conferences, gain teaching experience, collaborate with other students on similar projects, communicate the benefits of your research to the general public through workshops, lectures and presentations, or submit work for publication in an academic journal or book.
  • Third year - Primarily involves writing your thesis, though your research may still be in progress. After your supervisor gives their approval, you'll submit your thesis before undertaking a one to three-hour oral exam ( viva voce ) in which you'll discuss and defend your thesis in the presence of at least one internal and external examiner.

How do I find a PhD?

As a PhD is different to other degrees, you're committing to more than simply an advanced qualification. You've chosen to engage in a large-scale independent research project and so you'll need to take into account a range of factors that will drive your search.

A methodical approach to the process is required and you'll need to consider the subject you're interested in carrying out research in and the type of Doctorate you're looking for, making sure this is the right project for you. Only when you're fully prepared and have a good idea of your research proposal should you search for PhD opportunities .

What other types of Doctorate are there?

Alternative types of PhD include:

  • Higher Doctorate - These are usually granted on the recommendation of a committee of internal and external examiners, which assesses a portfolio of published, peer-reviewed research you've undertaken over the course of many years. This type of Doctorate is usually for those with several years of academic experience. Common award titles include the Doctor of Civil Law (DCL), Doctor of Divinity (DD), Doctor of Literature/Letters (DLit/DLitt/LitD/LittD), Doctor of Music (DMus/MusD), Doctor of Science (DS/SD/DSc/ScD) and Doctor of Law (LLD).
  • Integrated/New Route PhD - This four-year PhD course is offered by over 30 universities and involves taking a one-year MRes before studying a three-year PhD. It combines taught elements with independent research, allowing students to learn different methodologies while building their transferable skills.
  • Professional Doctorate - Geared towards students of vocational subjects such as medicine, education and engineering, professional Doctorates are focused on teaching and so normally involve smaller research projects and thesis component. They're often favoured by those aiming for a career outside of academia and are usually supported by employers.

How much does a PhD cost?

Tuition fees vary, but usually fall between £3,000 and £6,000 per year for UK students and those from the European Union (EU) with settled status. UK Research Councils pay universities £4,786 per year (from 2024/25) on behalf of each funded PhD student, so this gives a good indication of the average figure.

For EU students looking to pursue a Doctorate in 2024/25, you'll need to have gained settled or pre-settled status to be eligible for student finance - see PhD loans .

Non-EU students may pay considerably more for their tuition fees.

Despite this, many PhD students are now part or fully funded - scholarships and bursaries are widely available, and particular attention should be paid to Research Council grants .

PhD studentships and assistantships involving a mixture of research and teaching are also common, with scientific studentships usually paid at a higher rate.

Read more about funding postgraduate study .

How do I apply for a PhD?

Some students propose their own research area and apply for funding, while in some cases a supervisor may already have funding for a project and advertise it like a job. When making a PhD application, you'll typically be asked to submit:

  • an academic CV
  • your academic transcripts
  • two or three academic references
  • a personal statement
  • a research proposal.

International students without settled UK status looking to study certain courses in medicine, mathematics, engineering and material sciences are required to comply with the Academic Technology Approval Scheme (ATAS) .

This involves undergoing a security clearance process with the Foreign, Commonwealth & Development Office. International students may also have to prove their English proficiency.

Can I study a PhD abroad?

As the aim of postdoctoral research is to stretch the boundaries of understanding within your chosen field, you may find that the best place to begin your research lies overseas.

According to the Higher Education Student Statistics: UK, 2021/22 , 113,000 postgraduate research students are based in the UK, with 46,350 of these identified as international PhD candidates.

While studying in the UK has proved a strong draw for foreign PhD students, a number of other countries have also proved themselves to be research-orientated nations.

The following 15 countries all feature within the top 100 of the QS World University Rankings 2024 :

  • Netherlands
  • New Zealand
  • Switzerland

If you're interested in studying a PhD abroad, explore our country profiles .

What can I do next?

Your ability to critically analyse, display intellectual maturity, and research independently and honestly is highly valued within academia and the workplace.

Many students who undertake a PhD get an academic job or become an industry researcher, possibly following the PhD with postdoctoral study, then a fellowship or lectureship.

Other career options will depend on your study area. For instance, according to HESA's Graduate Outcomes 2020/21 data, a significant number of PhD graduates went on to work in teaching, natural and social science, therapy, and business, research and administrative careers.

PhD Candidate vs Student: What’s the Difference?

Lisa Marlin

Many people use the terms “PhD student” and “PhD candidate” interchangeably. However, these terms actually mean something quite different, including a different status level at universities.

We’re here to define the differences between a PhD candidate vs student, as well as other essential information, before you continue your educational journey.

Table of Contents

What I s a PhD student?

A doctoral student is anyone who is enrolled in a doctorate degree, also referred to as a Doctor of Philosophy (PhD) program. PhD students are typically required to complete a certain number of course credits and sit qualifying exams. Next, they can move on to conduct research and present it in the form of a dissertation.

A PhD is centered around self-directed research and possibly teaching/running tutorials, but they typically also involve a substantial amount of coursework and require attending classes, either online or in person.

Unlike candidates, PhD students are in the process of completing the required coursework for the degree. They haven’t passed the relevant qualifying exams yet.

What Is a PhD Candidate?

A PhD candidate has completed the required coursework and passed the qualifying exams for their doctorate program. They are currently working on their dissertation.

Most PhD students need to go through an application process  and show they meet certain requirements such as a relevant master’s degree . To become a PhD candidate, doctoral students need to pass an internal application process, typically involving a set of exams.

This stage involves significant research usually in innovative areas and incorporating this into a dissertation (this stage is sometimes referred to as “all but dissertation” [ABD]), as they’ve completed all other aspects of the program and satisfied these requirements. To complete their doctoral journey, a PhD candidate must defend their dissertation. Once they’ve successfully done this, they will be awarded their degree and move from PhD candidate to doctor of their chosen field.

PhD Candidate vs Student: 6 Key Differences

view of students in lecture hall from above

There are a number of key differences between a PhD student vs PhD candidate, from their status to the structure and nature of study.

Note: Some universities have recently started adopting hybrid approaches (where there is no clear difference between PhD students and PhD candidates). These programs don’t involve any qualifying exams and students typically begin the dissertation as part of their coursework. Most schools, however, continue with the traditional distinction between a PhD candidate and PhD student.

1. Program Stage

A PhD student could be at any stage of the doctoral program . Coursework still needs to be completed and qualifying exams must be passed. Students may be in the initial stage of the program or about to complete the coursework (before beginning their research).

On the other hand, a PhD candidate has completed all coursework and has at least started their research. They may have completed their dissertation and are preparing to defend it.

2. Research Progress

A PhD student may not have selected their research topic or settled on a particular research question. A candidate’s research is in progress and they should already have a clear research question.

3. Relationship with Advisors

A PhD student may not yet have an advisor. A candidate has an established working relationship with their advisor and works closely with them to complete their research and dissertation.

4. Level of Support

Although they work closely with an advisor, a PhD candidate is generally expected to work more independently than a student enrolled in a doctoral student. Once candidates reach this stage of their doctorate, they typically won’t receive as much direction or supervision.

5. Flexibility and Structure

Understandably, PhD candidates have more freedom and flexibility in their work. Most candidates choose their area of research, as well as the methods used to conduct their work. As part of their coursework, PhD students usually have to work within a set structure (e.g., completing core subjects, meeting deadlines).

Being a PhD candidate comes with a certain degree of status. If they’ve demonstrated a degree of expertise through completing qualifying exams, candidates can put the letters PhD(c) after their name.

Tips for PhD Candidates

view of library stacks on all three sides

A PhD is an advanced degree designed to demonstrate expertise in a given field, as well as high-level skills and abilities in various areas (including research and writing). As such, earning a doctorate can be a challenging process.

The following tips for doctoral candidates will help you put your best foot forward and set yourself up for success.

Stay Organized

Because PhD candidates have to balance many competing priorities, organization is essential. Using organizational tools such as calendars,  note-taking apps , and project management software can help you keep track of deadlines and meet your targets.

Focus on Your Research

PhD candidates likely have busy schedules with plenty of demands (such as teaching commitments and crafting a dissertation). As it’s the backbone of any doctoral program, be sure to prioritize this part of your work and monitor progress to stay on track.

Actively Seek Out Feedback

Because PhD candidates often work independently, there’s a risk of feeling isolated. Ask your advisors, mentors, and fellow candidates for feedback and advice. This will help ensure that you’re considering all aspects of your research question and multiple solutions, rather than focusing too intensely on a single area.

Take Advantage of Networking Opportunities

Networking is one of the biggest benefits for PhD candidates, so take full advantage of these events. Use this time to build a strong network of professors, advisors, fellow candidates, and other professionals you meet at conferences and events.

Take Care of Yourself

A PhD program can be taxing, and it’s easy for your mental and physical health to take a backseat. Make sure you exercise, eat well, and get enough sleep . Remember: Resting and recharging is crucial for working on your dissertation.

How Long Is a Typical PhD Candidacy?

view of ivy league building with autumn leaves

Most PhD students require 1-2 years to complete their coursework and pass their qualifying exams. However, the length of a PhD candidacy is much more open. In most cases, programs take between two and five years, depending on:

  • the complexity of the field of research
  • the candidate’s other commitments, such as teaching load
  • other abilities, such as a candidate’s level of organization.

Once a PhD candidate has completed their dissertation, they have to defend it successfully before a panel of faculty members before they can earn their doctorate degree. This process of defending a PhD dissertation can take several months.

Some universities specify a maximum length for PhD candidacy duration. For example, Carnegie Mellon University limits this to six years .

Benefits of Being a PhD Candidate

Being a PhD candidate can be rewarding for several reasons:

1. Research Opportunities

You’ll be exposed to vast research opportunities in your field. You may contribute to valuable discoveries while developing advanced knowledge and skills.

2. Networking

Through your PhD candidacy, you’ll also be in a great position to build gain a stronger network of fellow professionals.

3. Critical Thinking

A PhD candidacy can help you develop high intellectual independence and critical thinking skills.

4. Career Opportunitie s

A PhD is an advanced degree that allows you to build a rewarding career in the academic, government, and private sectors. PhD-holders can also expect to earn more than other graduates and are most likely to find a job.

5. Salaries

According to Northeastern University , professionals with a doctorate degree earn an average annual salary of $99,290 on average (and much more for the highest-paid PhDs ) and have a 1.5% unemployment rate. For master’s degree holders, the average annual salary is $81,867 average annual salary and a 2.6% unemployment rate.

6. Personal Fulfillment

Being a PhD candidate can help you pursue your passions. This advanced qualification will allow you to become a specialist in your chosen field, allowing you to hone in on the exact subject thatl fulfills you the most.

Qualifying Exams to Become a PhD Candidate

arm in grey sweater writing in notebook

While requirements vary by program, to become a PhD candidate, most students will need to pass a set of exams. These will test students’ knowledge in the field, measure their research skills, and ensure they’re ready to start their dissertation research.

Traditionally, qualifying exams for PhD candidates involved a written test and an oral exam. These will cover a range of topics related to your field of study, with the oral component designed to demonstrate your level of understanding.

Some universities have recently started to issue doctoral students with a set of questions and have them submit the answers within a set timeframe (usually around two weeks). Other schools ask prospective doctoral candidates to submit a dissertation proposal instead of an exam.

Frequently Asked Questions

Can a phd candidate be called a doctor.

In most cases, a doctoral candidate cannot be called a doctor until after they successfully defend their dissertation and receive their doctorate.

Can I Put ‘PhD Candidate’ after My Name?

Once you’ve passed qualifying exams and embarked on dissertation research, you’re technically entitled to put “PhD candidate” or “PhD (c)” after your name. However, this is uncommon and not always recommended. It is generally more acceptable to mention that you are pursuing a doctorate (along with the field of research and university) or that you expect to complete your PhD in a certain year (on your CV and online profiles).

How Long Can You Be a PhD Candidate?

There isn’t a set length of time that a person can be a PhD candidate. The length of candidacy depends on a range of factors, including the subject of research and program requirements. Most PhD candidates complete this phase in around 3-5 years (where some university programs have set limits).

Do PhD Students Take Classes?

Yes, most PhD students must take classes and complete coursework as part of the first 1-2 years of their doctorate program. Once they’ve completed this coursework and passed qualifying exams, they move on to work on their research dissertation. At this stage, they’ll be considered a PhD candidate.

Key Takeaways

Now that you know the differences between PhD candidates vs. students, you’ve got a deeper understanding of how to obtain a doctorate. However you slice it, both will help you build your knowledge and skills to become an expert in your field.

However the program is structured, a PhD is a highly valuable degree that allows you to become a high-level professional and build a successful career.

What is a doctorate.

A doctorate is a research-based academic degree. It is considered a terminal degree in most disciplines, meaning it represents the highest level of education a student can obtain in their chosen field.

A doctorate is awarded to students who have undergone a lengthy research process and made a significant contribution to the body of knowledge in their field of study. It takes multiple years to complete, during which students work closely with a supervisor and focus on a specific dissertation topic. Completing a doctorate might also involve teaching and comprehensive examinations.

A doctorate serves as solid proof of a person’s level of knowledge and expertise. It demonstrates that you have mastery over your chosen subject, and helps establish you as an expert. This level of expertise comes with top-tier job opportunities and the potential to earn top salaries in your chosen profession.

Doctorate vs PhD: Key Differences

While many people use the terms doctorate and PhD interchangeably, there are key differences between the two. These differences have to do with the application of these degrees. However, both terms refer to terminal degrees, so they hold the same value.

A Doctor of Philosophy degree, or PhD, is a research-oriented degree that demonstrates a person’s ability to contribute new knowledge to their chosen field. A student who pursues a PhD usually does so to answer a specific question, conduct original research to provide an answer, and use their findings to advance their field.

On the other hand, the term doctorate is broader and typically refers to a professional or clinical degree. This means that a person who obtains it has demonstrated an ability to apply advanced knowledge in a particular field in their professional life. Professional doctorates of this kind are awarded, for instance, to medical doctors or doctors of juridical science.

PhD Requirements: How to Get a PhD

While each PhD degree program will have unique requirements depending on the school and field of study, there are some common requirements you need to complete to get a PhD. Keep reading to find out about the most common requirements to earn your advanced degree.

PhD Statement of Purpose

A PhD statement of purpose is a document that clearly outlines your goals for your PhD, your academic credentials, and the reasons why an academic committee should approve your project. It is typically between 500 to 1,000 words long and gives prospective students an opportunity to explain how their research project will make a relevant contribution to their field.

How Many Credits Is a PhD?

Typically, it takes between 90 and 120 credits to complete your PhD studies. However, this number can be as low as 60, depending on the degree type, area of study, and state, regional, or institutional requirements. Credit hours for graduate students are usually divided between course work, research hours, and dissertation work.

Other Common Requirements for a PhD

  • Coursework. While coursework is not the main focus of a PhD, students will usually have to enroll in a few core courses during their first or second year of grad school. They might also have the opportunity to enroll in elective courses, which offer a chance to learn about other fields of study.
  • Qualifying exams. A common component of many PhD programs is a set of qualifying exams. Students must successfully pass these comprehensive exams toward the end of their degree in order to demonstrate their level of competence in their field. These tend to be oral exams.
  • Teaching. Many PhD programs include a teaching component. Students are required to teach basic courses, typically to fresh undergrad students, which helps them develop teaching skills.
  • Research. Conducting original research on a particular subject is typically the main component of a doctorate program, and takes up the bulk of doctoral candidates’ time.
  • Dissertation. Throughout their program, PhD candidates need to complete a dissertation based on the original research they’ve conducted. Graduate students do this under the guidance of a qualified faculty member.
  • Dissertation defense. Once the dissertation is approved, PhD students need to successfully defend their research in front of a panel of experts in their field before they are awarded their degree. This is the final step in the dissertation process.

How Do PhD Programs Work?

Typically, PhD degree programs work based on a mix of coursework and research conducted over three to four years, although this can last longer depending on the program and the pace at which a student completes their research. Coursework is typically completed towards the beginning of the program, and towards the end, the dissertation or thesis becomes the main focus.

In addition, students must fulfill other program requirements throughout this period. This might include teaching undergraduate students, completing a residency, passing qualifying exams, or attending conferences or colloquia. The final step is usually an oral defense in front of a panel of experts, who are selected to evaluate the quality of the research and the value of the results obtained.

Do You Need a Master’s to Get a PhD?

No, a master’s degree is not always required to pursue PhD studies. Many programs in the US allow students to apply to a PhD program straight after completing their bachelor’s degree. Other programs offer dual degrees, meaning that you will obtain a master’s degree while you work toward your doctorate.

What Comes After a Doctorate Degree?

In many fields, the usual step after a doctorate degree is a postdoc. This is an option for those wishing to pursue a career in academia and continue doing research in their field. However, an academic career is not the only option. Because a doctorate is a terminal degree, graduates can easily move on to professional positions in other types of organizations in their chosen field.

PhD Dissertation vs Thesis

The main difference between a dissertation and a thesis is the scope of the research being conducted and the type of degree you are awarded after completing it. Often, the terms are used interchangeably, or they can hold different meanings in European countries, which causes some confusion regarding their nature. Keep reading to understand the differences between a PhD dissertation and a thesis in the US.

What Is a PhD Dissertation?

A PhD dissertation is a piece of scholarly work that presents the original research carried out by a doctoral student during the length of their program. It discusses the scope, methodology, results, and conclusions of the research at length. The end goal of a doctoral dissertation is to produce results that help advance human knowledge in a given field.

PhD Dissertation Defense

A PhD dissertation defense is the process in which a PhD candidate defends their research in front of a panel of experts in their field. During the defense, members of the panel ask questions regarding the information presented, providing the candidate an opportunity to back up their work and demonstrate the level of expertise they’ve achieved after years of dedicated work.

What Is a PhD Thesis?

In the US, as opposed to some European countries, the term thesis refers to a shorter academic paper that is usually presented for the completion of a master’s degree. It can also sometimes be a requirement for honors students completing a bachelor’s degree. The information presented in a thesis is usually drawn from existing sources, rather than from original research conducted by the student.

PhD Thesis Defense

A thesis defense is usually not a mandatory requirement for master’s students, although this varies according to your school and department. The thesis is still an in-depth piece of scholarly writing and serves as a testament to a student’s mastery of a given subject, and a defense serves as an opportunity to engage a panel of experts and defend the contents of your paper.

How Long Does It Take to Earn a Doctorate?

Most doctoral programs are designed to be completed in four to six years. However, it can take up to seven and a half years to earn a doctoral degree from the start of graduate school, according to data presented by the National Science Foundation.

A number of factors can affect how long it takes students to earn their PhDs. They include the structure of their chosen program, the type of research being conducted, and the support provided by the institution. On average, students completing doctoral programs in science and engineering fields finish faster than their counterparts in non-science and engineering fields.

How Hard Is It to Get a PhD?

It can be very hard to get a PhD. Working for several years on a particular dissertation topic can be very trying. Aside from the time commitment, the depth of research that is part of the dissertation process can also be challenging. Admissions to a top education institution can be extremely competitive, as usually there are only a handful of positions available for hundreds of applicants.

What Is the Easiest PhD to Get?

PhDs in the humanities, social sciences, and education are typically regarded as the easiest to obtain. However, this truly comes down to how interested you are in your chosen dissertation topic and your level of commitment to making a relevant contribution to human knowledge, both of which can greatly influence your perception of the difficulty of the degree.

How Much Does a PhD Cost?

According to data from the National Center for Education Statistics, the average yearly cost of graduate programs in the US is $19,792. Data from the QS World University Rankings suggest that the yearly cost of a PhD in the US ranges from $28,000 to $40,000. The total cost of a PhD can greatly vary depending on the university, length of the program, and funding options available for doctoral study.

This is also an excellent time to assess funding opportunities and contact potential supervisors to gauge their interest in and ability to support you during your studies.

In order to enroll in a doctoral program, you will need to provide quite a few documents with your application. Every school is different, but the most common requirements are transcripts, letters of recommendation, and a strong statement of purpose. Make sure you check the specific requirements of your chosen program, and prepare to be interviewed by faculty members.

After being accepted into a doctoral program, you should outline what the next few years will look like. What requirements do you need to complete to earn your PhD? Spend time crafting a realistic timeline that can help you stay on track and complete every step successfully. This includes teaching, participating in conferences, and successfully completing your qualifying exams.

The final step to obtaining your PhD is to successfully complete your research and compile your results in your dissertation. Once it is reviewed and approved by your supervisor and readers, you will have to defend it as well. It can be a trying process, but the results will be worth it.

How to Choose a PhD Program

In order to choose a PhD program that is right for you, there are several factors you should consider. A PhD is a strong commitment both in terms of time and money, so the decision shouldn’t be made lightly. Keep reading to find out how to choose a PhD program.

PhD Acceptance Rates

The PhD acceptance rates of a university give you an idea of how likely you are to be admitted to your chosen program. This number is a reflection of how competitive a program is and the funding the department receives. Use this information to orient yourself to the selection process, as applying to a variety of programs with different acceptance rates can increase your chances of being accepted into one of them.

Keep in mind that acceptance rates are usually measured by department, not university. For instance, Columbia University has an acceptance rate of four to six percent for its psychology PhD program , and an acceptance rate of five to seven percent for its history PhD .

PhD Dropout Rates

PhD dropout rates are important to consider, as they give you an idea of how supported students are in a particular program and how likely you are to complete your doctorate. In the US, PhD attrition rates, or dropout rates, can range from 40 to 50 percent , so take your time to find a university and program with a high success rate to ensure you will be able to finish and obtain your degree.

Faculty Members

One of the key relationships you will have during your time as a PhD student will be with your supervisor. You will also be working closely with other members of your department. As such, make sure to research the faculty to ensure that their interests and research projects align with your own. During the research stage, you can even reach out to them to find out about the department, ask about funding opportunities, and receive relevant career advice.

Funding Opportunities

A PhD can be costly, but there are many ways to offset those costs to make it more manageable. Be it scholarships, grants, or work opportunities, make sure to research all funding opportunities available so you can select a program that aligns with your financial situation. Many universities offer fully-funded programs to outstanding students, so do your homework and find a program that doesn’t leave you financially crippled in the long run.

When you commit to a PhD, you are also committing to several years of work. Unless you are planning to complete your program fully online, you should take into account the place where you will be moving to continue your studies.

Do you prefer big cities or small college towns? Which part of the country would you be willing to relocate to? Take some time to reflect on your preferences so you can choose the best location according to your needs and preferences.

In this article, we delve into the disparity between a PhD candidate and a PhD student, shedding light on the roles, responsibilities, and progression associated with each stage. We explore the specific criteria that differentiate a student from a candidate and the various milestones marking the transition. Additionally, we delve into the responsibilities and expectations that accompany each designation, illuminating the unique experiences and commitments faced by PhD candidates and students.

Furthermore, we acknowledge the variability in terminology across international boundaries, academic institutions, and disciplinary fields, providing insights into how different contexts might influence the usage of these terms. By the end, readers will have a comprehensive understanding of the contrasting aspects between a PhD candidate and a PhD student, facilitating informed conversations and a deeper appreciation for the intricate nature of doctoral education.

Introduction

Who is a phd student, when phd student attains status of phd candidate, variation in terminology.

Pursuing a PhD (Doctor of Philosophy) degree involves conducting original research in a specific field of study, making a significant contribution to knowledge, and demonstrating a high level of expertise. It is the highest academic qualification one can attain and is highly valued in academia, research institutions, and certain industries. A PhD signifies a deep understanding of a subject area, advanced analytical and critical thinking skills, and the ability to conduct independent research.

While the terms “PhD candidate” and “PhD student” are often used interchangeably, there are subtle differences between the two.

A PhD student typically refers to an individual who has been admitted to a doctoral program, actively engaging in coursework and other program requirements. They are in the early stages of their doctoral journey and are working towards completing the necessary academic components of their degree. On the other hand, a PhD candidate is typically someone who has progressed beyond the coursework stage and has advanced to the research phase of their program. They have usually completed comprehensive exams, passed a research proposal defense, and are actively engaged in independent research for their dissertation or thesis.

The purpose of this article is to provide a comprehensive understanding of the distinction between a PhD candidate and a PhD student. By exploring the criteria, milestones, and responsibilities associated with each designation, this article aims to clarify the unique experiences and progression of doctoral students. It also seeks to address the varying terminology used across different contexts and disciplines, enabling readers to grasp the intricacies of the doctoral journey and fostering informed discussions around this topic.

Through this article, readers will gain a comprehensive understanding of the journey from being a PhD student to becoming a PhD candidate and the distinct roles and responsibilities associated with each stage.

A PhD student is an individual who has been admitted to a doctoral program and is actively engaged in pursuing their doctoral studies. They are at the initial stages of their doctoral journey, seeking to expand their knowledge, skills, and expertise in a specific field of study. PhD students play a vital role in academic research communities as they contribute to the generation of new knowledge and the advancement of their discipline.

PhD students are required to complete a set of coursework specific to their field of study. These courses are designed to provide a foundation in the discipline, enhance research skills, and broaden the student’s understanding of relevant theories and methodologies. Coursework may include seminars, advanced classes, and specialized topics. The specific coursework requirements can vary between programs and disciplines.

Example: Imagine a student named Alex who has just been accepted into a doctoral program in psychology. At this stage, Alex is considered a PhD student as they begin taking relevant coursework, attending seminars, and collaborating with faculty members. They are laying the foundation for their research and acquiring the necessary knowledge in their field.

Who is a PhD Candidate?

Advancement from being a PhD student to a PhD candidate typically involves meeting specific requirements set by the doctoral program. These requirements may vary depending on the institution and field of study but often include successful completion of coursework, exams, and other program-specific milestones.

One of the primary requirements for transitioning to a PhD candidate is the successful completion of coursework and exams. PhD students are expected to complete a designated set of courses, which provide a broad understanding of their field and research methodologies. They are also required to pass comprehensive exams, which assess their comprehensive knowledge and understanding of their research area.

As part of the transition to becoming a PhD candidate, students typically prepare and defend a research proposal. The research proposal outlines the scope, objectives, methodology, and significance of the intended research. The proposal defense may involve presenting the proposal to a committee of faculty members, who evaluate its feasibility, rigour, and contribution to the field. Additionally, PhD students often have to pass comprehensive exams, which test their knowledge of their research area and related disciplines.

If you are not familiar with writing PhD proposal and making PhD proposal presentation, then visit my articles on “ How to Write PhD Proposal Presentation to the University ” and ” How to Make a PhD Proposal Presentation to the University Panel” . These articles will guide you through the process of preparation and presentation of PhD proposal to the University panel.

Upon successful completion of the requirements, PhD students are often granted candidacy status. Advancement to candidacy signifies that the student has demonstrated the necessary knowledge, skills, and potential to conduct independent research and contribute to their field. This status allows students to focus more exclusively on their research and dissertation work.

Once students become PhD candidates, there is a shift towards an increased emphasis on independent research. They are expected to dedicate a significant portion of their time and effort to conducting original research, collecting data, analyzing results, and making novel contributions to their field. The focus is primarily on their dissertation or thesis work, which serves as the culmination of their doctoral studies.

Example: Let’s consider a PhD student named Alex in the field of computer science. After completing their coursework and passing comprehensive exams, Alex develops a research proposal outlining their intention to investigate the applications of machine learning in cybersecurity. They present the proposal to a committee of faculty members, who assess the feasibility and potential impact of the research.

Alex successfully defends their research proposal and is granted candidacy status, transitioning from a PhD student to a PhD candidate. With candidacy status, Alex’s focus shifts towards conducting independent research. They spend considerable time collecting and analyzing cybersecurity datasets, developing and refining machine learning algorithms, and testing their effectiveness in detecting and preventing cyber threats.

As a PhD candidate, Alex works closely with their advisor, regularly discussing research progress, seeking guidance, and receiving feedback. They collaborate with other researchers in the field, attend conferences to present their findings and contribute to the scholarly community through publications. The focus is now on producing an original and significant contribution to the field of computer science through their dissertation.

The transition to PhD candidacy marks a critical stage in the doctoral journey, as it signifies the ability to independently drive research and make scholarly contributions. PhD candidates like Alex are immersed in the world of research, expanding knowledge, and pushing the boundaries of their field.

Terminology related to PhD candidates and PhD students can vary internationally and among different academic institutions. In some countries, the terms “PhD candidate” and “PhD student” may be used interchangeably, while in others, there may be specific distinctions. For example, in the United States, “PhD student” is commonly used, while in the United Kingdom, “PhD candidate” is more frequently employed. Additionally, different universities or institutions may have their own terminology preferences, which can create further variation.

Terminology can also vary based on the disciplinary field of study. Different academic disciplines have their own conventions and terminology for referring to individuals pursuing a doctoral degree. For instance, in the sciences, one might encounter terms like “graduate researcher” or “doctoral candidate.” In the humanities and social sciences, the terms “PhD candidate” and “PhD student” are often used. This variation reflects the specific linguistic and cultural norms within different academic domains.

In Canada, for instance, doctoral students are commonly referred to as “PhD candidates,” regardless of their stage in the program. In Australia, “PhD candidate” is the preferred term for those who have completed the required coursework and have advanced to the research phase. In contrast, in the United States, “PhD student” is frequently used to refer to individuals at all stages of their doctoral studies.

Disciplinary variations can also be observed. In engineering, individuals pursuing a doctoral degree are often referred to as “PhD students” or “doctoral students.” In contrast, in the field of education, the term “PhD candidate” is commonly used to denote those who have advanced to the research and dissertation stage.

It is important to note that these examples represent general trends, and there can still be variation within specific institutions and programs. The usage of terminology can evolve over time and may be influenced by regional or institutional preferences.

The distinction between a PhD candidate and a PhD student holds significant importance in the realm of doctoral education.

While these terms are often used interchangeably, they represent different stages and responsibilities within the doctoral journey. A PhD student is in the initial stages of their program, actively engaging in coursework, research, and academic requirements.

On the other hand, a PhD candidate has advanced beyond coursework, passed comprehensive exams, and is focused primarily on independent research and the completion of their dissertation.

Frequently asked questions

What is a phd.

A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.

A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.

Frequently asked questions: Graduate school

In the US, most graduate school applications require you to include:

  • Transcripts from previous educational institutions
  • Standardized test scores (such as the GRE or MCAT)
  • A graduate resume
  • 2–3 letters of recommendation
  • A statement of purpose

Some programs may ask you to write a personal statement in addition to, or instead of, a statement of purpose. You may also be asked to an interview .

Always carefully read the application instructions for the specific program you’re applying to.

Most medical school programs interview candidates, as do many (though not all) leading law and business schools.

In research programs, it depends—PhDs in business usually do, while those in economics normally do not, for example.

Some schools interview everyone, while others only interview their top candidates. Look at the websites of the schools you’re applying to for more information on whether they conduct interviews.

In addition to thinking about your answers for the most commonly asked grad school interview questions , you should reach out to former and current students to ask their advice on preparing and what sort of questions will be asked.

Look back through your resume and come up with anecdotes that you could use for common questions, particularly those that ask about obstacles that you overcame. If you’re applying for a research program, ensure that you can talk about the previous research experience you’ve had.

You should also read as much research in your field as possible. Research the faculty at the schools you’re applying to and read some of their papers. Come up with a few questions that you could ask them.

Graduate schools often ask questions about why you are interested in this particular program and what you will contribute.

Try to stay away from cliche answers like “this is a good program” or “I got good grades in undergrad” and focus instead on the unique strengths of the program or what you will bring to the table. Understand what the program is looking for and come up with anecdotes that demonstrate why you are a good fit for them.

Different types of programs may also focus on different questions:

  • Research programs will often ask what topics you’d like to research and who you would like to work with, as well as specific questions about your research background.
  • Medical schools are interested in your personal motivation, qualities such as integrity and empathy, and how you’d respond to common ethical dilemmas.
  • Business schools will focus on your past work experience and future career prospects, and may be particularly interested in any experience you have managing or working with others.

Some students apply to graduate school straight from undergrad, but it’s also common to go back to school later in life. The ideal time to do so depends on various financial, personal, and career considerations . Graduate school is a big commitment, so you should apply at a time when you can devote your full attention to it.

Your career path may also determine when you should apply. In some career fields, you can easily progress without a graduate degree, while in others—such as medicine, business, and law—it’s virtually impossible to move up the career ladder without a specific graduate degree.

Most graduate school applications for American graduate programs are due in December or January for a September start.

Some types of programs, especially law school, are rolling applications, meaning that the earlier you apply, the earlier you’ll hear back. In this case, you should aim to apply as early as possible to maximize your chances.

Medical school follows a completely separate timeline with much earlier deadlines. If you’re applying for medical school, you should speak to advisors at your university for more information.

A good starting point to aim for is about 18 months before you would start the program, or 6–9 months before the applications are due.

In the first few months of the process, research programs and study for any standardized exams you might need.

You can then begin writing your personal statements and statements of purpose , as well as contacting people to write your letters of recommendation . Ensure that you give recommenders plenty of time to complete their letters (ideally around 2–4 months).

In the US, the graduate school application process is similar whether you’re applying for a master’s or a PhD . Both require letters of recommendation , a statement of purpose or personal statement , a resume or CV , and transcripts. Programs in the US and Canada usually also require a certain type of standardized test—often the GRE.

Outside the US, PhD programs usually also require applicants to write a research proposal , because students are expected to begin dissertation research in the first year of their PhD.

A master’s degree usually has a higher upfront cost, but it also allows you to start earning a higher salary more quickly. The exact cost depends on the country and the school: private universities usually cost more than public ones, and European degrees usually cost less than North American ones. There are limited possibilities for financial aid.

PhDs often waive tuition fees and offer a living stipend in exchange for a teaching or research assistantship. However, they take many years to complete, during which time you earn very little.

This depends on the country. In the United States, you can generally go directly to a PhD  with only a bachelor’s degree, as a master’s program is included as part of the doctoral program.

Elsewhere, you generally need to graduate from a research-intensive master’s degree before continuing to the PhD.

This varies by country. In the United States, PhDs usually take between 5–7 years: 2 years of coursework followed by 3–5 years of independent research work to produce a dissertation.

In the rest of the world, students normally have a master’s degree before beginning the PhD, so they proceed directly to the research stage and complete a PhD in 3–5 years.

A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.

All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.

It’s best to ask in person if possible, so first reach out and request a meeting to discuss your graduate school plans.

Let the potential recommender know which programs you’re applying to, and ask if they feel they can provide a strong letter of recommendation . A lukewarm recommendation can be the kiss of death for an application, so make sure your letter writers are enthusiastic about recommending you and your work!

Always remember to remain polite. Your recommenders are doing you a favor by taking the time to write a letter in support of your graduate school goals.

This depends on the program that you are applying for. Generally, for professional programs like business and policy school, you should ask managers who can speak to your future leadership potential and ability to succeed in your chosen career path.

However, in other graduate programs, you should mostly ask your former professors or research supervisors to write your recommendation letters , unless you have worked in a job that corresponds closely with your chosen field (e.g., as a full-time research assistant).

Choose people who know your work well and can speak to your ability to succeed in the program that you are applying to.

Remember, it is far more important to choose someone who knows you well than someone well-known. You may have taken classes with more prominent professors, but if they haven’t worked closely with you, they probably can’t write you a strong letter.

The sections in your graduate school resume depend on two things: your experience, and the focus of the program you’re applying to.

Always start with your education. If you have more than one degree, list the most recent one first.

The title and order of the other sections depend on what you want to emphasize. You might include things like:

  • Professional experience
  • Voluntary and extracurricular activities
  • Publications
  • Awards and honors
  • Skills and certifications

The resume should aim for a balance between two things: giving a snapshot of what you’ve done with your life so far, and showing that you’re a good candidate for graduate study.

A resume is typically shorter than a CV, giving only the most relevant professional and educational highlights.

An academic CV should give full details of your education and career, including lists of publications and presentations, certifications, memberships, grants, and research projects. Because it is more comprehensive, it’s acceptable for an academic CV to be many pages long.

Note that, outside of the US, resume and CV are often used interchangeably.

No, don’t include your high school courses and grades. The education section should only detail your college education.

If you want to discuss aspects of high school in your graduate school application, you can include this in your personal statement .

A resume for a graduate school application is typically no more than 1–2 pages long.

Note, however, that if you are asked to submit a CV (curriculum vitae), you should give comprehensive details of all your academic experience. An academic CV can be much longer than a normal resume.

Always carefully check the instructions and adhere to any length requirements for each application.

If you’re applying to multiple graduate school programs, you should tailor your personal statement to each application.

Some applications provide a prompt or question. In this case, you might have to write a new personal statement from scratch: the most important task is to respond to what you have been asked.

If there’s no prompt or guidelines, you can re-use the same idea for your personal statement – but change the details wherever relevant, making sure to emphasize why you’re applying to this specific program.

If the application also includes other essays, such as a statement of purpose , you might have to revise your personal statement to avoid repeating the same information.

The typical length of a personal statement for graduate school applications is between 500 and 1,000 words.

Different programs have different requirements, so always check if there’s a minimum or maximum length and stick to the guidelines. If there is no recommended word count, aim for no more than 1-2 pages.

A statement of purpose is usually more formal, focusing on your academic or professional goals. It shouldn’t include anything that isn’t directly relevant to the application.

A personal statement can often be more creative. It might tell a story that isn’t directly related to the application, but that shows something about your personality, values, and motivations.

However, both types of document have the same overall goal: to demonstrate your potential as a graduate student and s how why you’re a great match for the program.

The difference between doctoral students and doctoral candidates

Doctoral candidate vs. doctoral student, phd vs. practitioner doctorate.

  • Explore online doctorate programs

Many people who earn a doctoral degree will, at some point, be both a doctoral student and doctoral candidate. While these roles may seem mysterious from outside the (real or virtual) halls of academia, the distinction is fairly simple.

Before we cover the distinction, however, let’s get on the same page about doctoral degrees.

What is a doctoral degree?

In academia, one degree sits at the very top: the doctoral degree. Also referred to as a doctorate, a doctoral degree is the most advanced educational credential you can earn. Though some fields of study (like journalism) don’t have a doctoral degree, most typical academic fields do, as do the fields of health, medicine, law, education and business.

Doctoral programs can lead to a PhD in a variety of fields, such as literature, philosophy and history, or a practitioner doctorate in a field like business, health administration, nursing or education. Doctoral degrees involve years of intensive study, and many require a book-length dissertation. However, practitioner doctorates have different requirements and may not entail a dissertation.

Requirements of a doctoral program

Before graduate school, you must complete years of university courses, typically two degrees, before a program will consider admitting you. However, some programs have more lenient requirements than others.

Doctoral programs tend to be intentionally difficult and rigorous courses of study. As mentioned, there are several educational levels before a doctoral degree that both students and candidates will need to pass.

The requirements for a doctoral student include:

  • Prerequisite degrees: Doctoral programs usually require that students obtain a bachelor’s and a master’s degree first.
  • Required coursework: Each program requires different courses, but most will be in the student’s area of study, with some focused on adjacent or complementary subjects. Additionally, foundational coursework prepares students to learn about the research process.
  • Qualifying exams: Typically, students must pass qualifying exams to enter doctoral programs, but not all programs require entrance exams.

If a dissertation is part of the doctoral program, the doctoral candidate must:

  • Select a dissertation advisor or committee: During your time as a doctoral student, you will come into contact with many instructors. You will typically only interact with the instructors who are your dissertation advisor or on your dissertation committee. The committee is the audience for the doctoral candidate and ensures the candidate demonstrates command of the literature and methodologies relative to their field.
  • Choose your dissertation topic: This is a pivotal point in your journey to earning a PhD or doctorate. Many programs ask for a general topic as part of your initial application. Your advisors will help you to create a specific and unique dissertation topic that will fuel your work over the next several years.
  • Write the dissertation: Your dissertation or thesis will normally take a couple of years to write and will be a book-length culmination of your learning and research.
  • Defend your dissertation or thesis: After you submit your final draft to your dissertation committee, you will need to orally present your work to the committee, answer questions and defend your work.

The requirements for a doctorate take many years to complete. While some people complete doctoral degrees in three to five years, others take seven to 10 years. The time span depends on your specific area of study, whether you take classes on a full-time or part-time schedule and how long it takes to complete your dissertation. This also includes your level of focus and intent.

If you are interested in earning your doctorate, then it is important to understand the difference between being a doctoral candidate and a doctoral student.

What is a doctoral student?

A doctoral student is a person currently enrolled in a doctoral program at a university. Being a doctoral student involves completing a certain number of credits and coursework in an area of study and completing and passing several exams.

After students pass the qualifying exams (if the program requires it) and successfully complete required coursework, they become doctoral candidates.

What is a doctoral candidate?

A doctoral candidate leaves behind the structured learning schedule of a student. No longer does the candidate attend regular classes or take exams. Instead, they embark on a self-guided schedule for writing a dissertation. This culminates their studies and is tailored to their unique and individual areas of interest.

Doctoral candidates work closely with the advisors who make up their dissertation committee. The advisors provide guidance and critiques as the candidate writes a book-length dissertation. While the advisors can help along the way, what sets the candidate apart from the student is that, rather than simply learning what others have already discovered, they are conducting and writing about their own original, approved research — and then demonstrating what they’ve learned, as well as how it fits in the broader field of study or can be applied to tangible problems.

The meaning of candidacy in other doctoral programs

A PhD is not the only type of doctoral degree. There are also practitioner or professional doctorates, which may take the specific shape of medical doctorates, optometry doctorates, audiology doctorates, chiropractic doctorates, juris doctorates and others.

Such programs have their own conventions and terminology for various milestones. Some doctoral degrees, such as for law or medicine, focus on mastering the practice of a specific subject and the skills associated with that practice. As a result, terms such as candidate are not used universally among doctoral programs, and many of these programs do not include a dissertation.

A PhD, or Doctor of Philosophy, is a doctoral degree that is focused on expanding and enriching an area of research. A PhD student typically focuses on developing new and original knowledge based on theory. 

In contrast, a practitioner doctorate prepares students for leadership roles in their desired profession by applying existing knowledge to solve problems in their field or community. The practitioner doctorate generally involves rigorous curriculum, culminating in a dissertation or applied project that addresses a particular real-world problem.

Requirements of a practitioner doctorate and many practitioner programs

The requirements of a particular practitioner doctorate will vary according to the institution and the field of study. This makes sense when you consider that practitioner doctorates vary from juris doctorates to doctors of physical therapy.

While there may be similar experiences involved in the course of study, such as residencies or internships, the requirements are unique to the specific degree.

PhD candidate vs PhD student

I see researchers working on their PhD calling themselves PhD Candidates, other call themselves PhD students. What's the difference between a PhD Candidate and a PhD Student?

According to two posters on the WordReferences forums :

This terms vary from university to university, usually a PhD student is granted the candidate status after completion of a “comprehensive examination”, which occurs sometime after the first year.
Here in the U.S., a “Ph.D. Candidate” is a student who has completed all of the academic requirements for their degree, except their dissertation.

So this works in the USA and Canada I presume, because they have structured PhD programs where you attend courses as part of your PhD. Unlike most of the universities in Europe where a PhD student starts off directly with his/her PhD thesis. (Europe does have structured programs as well, but they are not as widely spread yet).

In some countries (e.g. The Netherlands where I obtained my PhD degree) you are not considered a student but a paid employee (staff) with the university. To discern between these, people sometimes translate their status to English using term "PhD candidate". Btw, this has nothing to do with the length of the program or your progress.

  • 4 It is also good to note that the salary a Dutch PhD receives is competitive with entry level jobs at say a consultancy or programming company, assuming of course there is funding to begin with. –  Paul Hiemstra Commented Jul 10, 2013 at 12:05
  • 5 @PaulHiemstra broadly speaking :) I would say there is at least a 500 euro gap. Especially after four years, the PhD salary is considerably below what a programmer or consultant with 4 years experience could expect. It's the same general range, but I wouldn't call it competitive. –  Peter Bloem Commented May 1, 2014 at 14:54
  • 12 @Peter The pay and working conditions are certainly near the top of the scale when you compare it to what PhD students in other countries get. –  Moriarty Commented May 1, 2014 at 16:20
  • @Peter, here in Brazil this gap varies a lot. A trainee in a small company usually makes less than a PhD student\candidate. So small companies rarely get the brightest people. OTOH, big companies easily pay entry salaries equivalent to the double of what a PhD candidate makes (triple if the applicant is a good interviewer). And excluding the IT field, the extra income from 4 years of experience is negligible. So it all depends of vacancies on the big companies of your city. –  Lucas Soares Commented Oct 30, 2014 at 15:10
  • 1 There is also a political component to it, because there are some politicians who want to change the status of PhD candidates from being an employee to being a receiver of a grant. Therefore, when I was still doing my PhD, I was emphasizing a lot that I was not a student, and I tell that to the current PhD candidates as well. –  damian Commented Aug 31, 2015 at 15:14

To expand on what JeffE said – "Every department is different.", here's an example from my university (a top UC school):

The math department is pretty rigorous and the "candidacy exam" is mostly a blackboard and chalk routine. They throw a bunch of stuff at you, poke holes in your proposal, make you sweat epsilons and deltas from all your pores before declaring you a "candidate".

The life/physical sciences departments require you to have a 20-30 page written proposal + a presentation on it + preliminary results (usually at least 1 journal paper) and your committee members grill you on the proposal.

In ECE/CS (applied, not theoretical), the labs/PIs are generally quite rigorous themselves and by the time a student is ready to take the candidacy exam, they've had at least 2 first author publications and 3-4 conference publications. At this point, their course is pretty set and the committee members don't generally feel like they need to say/do much (unless if there are serious flaws hitherto unnoticed). As such, the candidacy exam is more of a formality — no 30 page proposals (who reads them anyway?); just a presentation on the papers already published + future work remaining.

The bottom line from all this is — there are no standard rules/definitions/process involved in becoming a "PhD candidate". All it usually means is that "This person has shown an understanding of the fundamental concepts (on the day of testing), their proposal/work done is original and has potential and they've completed all course work/other requirements except for their thesis".

In Australia, (at least at my university), you start off as a 'Provisional Candidate'.

Then you complete a Dissertation Proposal - where you present a 20 or so page preliminary report and present it as a seminar to a group of peers - once passed, you receive a 'Confirmation of Candidature' then you proceed to complete the thesis as a 'Confirmed Candidate'.

This is usually done within the first 1-2 years of the PhD course.

  • 14 "Provisonal candidate"? I'd have preferred "Candidate candidate" –  Federico Poloni Commented Jul 5, 2013 at 16:00
  • 2 @FedericoPoloni well, that is what we're called before the Dissertation Proposal. –  user7130 Commented Jul 5, 2013 at 21:16
  • This is very similar to my experience in Switzerland. –  DarioP Commented Jun 22, 2015 at 8:33
What's the difference between a PhD Candidate and a PhD Student?

To someone outside your department, there is very little difference since people (i.e., prospective employers) just don't care about the terms. they want to know what you have accomplished so far.

To someone in a finite duration PhD (e.g., a "typical" 3-year UK PhD program), there is very little difference. It is simpler to just list your year.

To someone in a indeterminate length PhD (e.g., a "typical" US PhD program), it provides a nice milestone.

As other have said, the requirements to achieve candidacy vary widely between countries, universities, and even departments. That said, I think it is nearly universal (and that is going out on a huge limb in academia) that candidacy implies that the next "evaluation" will be on your thesis and apart from time limits or extraordinary circumstances that as long as you are willing to pay your tuition and fees the department will let you be a PhD Candidate.

At my institution (in the U.S.A.), you are considered a PhD student until you pass your qualifying exams. After passing, you are considered a PhD candidate.

The qualifying exam is usually taken around 2 years in the program, or after you have completed any required or recommended coursework. It consists of a written exam, which can be one or more questions from each of your committee members. The written exam at my institution is left up to the committee members discretion (the major adviser in reality), it can be open or closed book, very detailed, or more theoretical, 24 hour time period or maybe 1 month, even proctored by the committee member. The oral examination can also be anything. Committee members can ask very detailed questions or more theoretical questions. Preparing for the oral exam can be difficult, especially if you have members from other departments and backgrounds. For example, I have a Soil Scientist, Biologist, Fire Ecologist, Landscape Modeler, and Remote Sensing Specialist on my committee. They all asked very different question specific to their fields.

Three of my written exams consisted of about 8 questions and I was given 8 hours to complete. It was open book and not proctored. I took the exam from home. One exam was 12 questions and I was given a month (yes I sweated for a month!). They all asked very broad questions for the written exam to figure out which areas I had a solid understanding in, and which areas I needed improvement. The oral exam was basically 4 PhD's questioning (read interrogating!) me. They started with a few easy questions, but then asked more difficult questions from the areas I was not as knowledgeable in.

I think Jaap's reply is pretty much spot on, i.e. paid staff (as in the Netherlands, Germany...) vs. student status (as in the UK, for example).

Personally, I prefer "PhD candidate" because people here are massively prejudiced against "students" (young, irresponsible, constantly partying...) despite the fact that I'm officially registered as a student rather than staff.

Just to make it clear that people are not obliged to use one thing or the other.

It can be different depend on region, country, university or even department.

In my department in a university in Taiwan, we need to finish all required credit course and submit one international journal as milestone to be qualified as PhD Candidate.

At the university I attended in the UK, one was considered to be on provisional status until passing the viva, which was not only an oral "interview" but also included a thorough review of all research completed at that point, a 20,000 word critical paper, and a detailed thesis plan. After that point, the successful student was advanced to candidacy, while the unsuccessful student was awarded an M.Phil.and dismissed from the program. This procedure was standardized throughout the university graduate school regardless of department. For candidates, the only obstacle left was the defense of the thesis.

PhD students should complete all the coursework before becoming PhD Candidate. After completing all the coursework, PhD students have to pass the comprehensive written exam (and comprehensive oral exam) to become PhD Candidate. The amount of rigor of comprehensive exam depends on department to department. Some department requires that you pass the comprehensive exam on all the four (or five) seminar areas plus the methods that you have taken. Others require that you declare your major area and pass the comprehensive area on only that major area plus the methods. Department may also require you to come up with a framework for your dissertation topic before they grant you the candidacy status. Again, the variation exists between department in how they grant the candidacy. Once your status change from PhD Student to PhD Candidate, you are no longer required to take courseworks. However, you should be enrolled in the pre-dissertation and dissertation hours (normally 24 hrs; 6 hours per semester to maintain full-time status) to continue your dissertation. You work with your dissertation chair and committee after comprehensive exam. PhD candidate are also called Doctoral candidate, and ABD - All But Dissertation.

  • 4 PhD students should complete all the coursework before becoming PhD Candidate - this is not generally true (i.e., not in all fields/all departments). –  ff524 Commented Aug 18, 2014 at 13:36
  • 3 I downvoted this for being specific to a very limited area without specifying that area or even mentioning this fact. –  Tobias Kildetoft Commented Aug 18, 2014 at 15:19

When you see PhD CANDIDATE think he/she is a CANDIDATE for a job in their field.

Versus PhD student they are still a student learning their field of study.

In Texas public University you are a candidate when you pass all of your doctoral exams. Usually at this point you have already completed all of your course work. You are wrapping up your research projects, writing papers to be published, writing dissertation and looking for a job.
