What is a dissertation?

October 31, 2019

A dissertation is a written document that summarizes research.

It is the final step of a PhD program, and the culmination of a student’s doctoral studies.

“The dissertation is a source of pride for doctoral students,” Dinah Manns, PhD, faculty chair at Capella University, says. “The dissertation is often a compilation of academic and practical knowledge, and in many cases, it can be the student’s first publication.”

Here, Manns explains the content and format of this important piece of scholarship.

From student to scholar

The major objective of any doctoral program is to assist a student in becoming an independent researcher, and a dissertation is a large part of that. “Not all doctoral programs require a dissertation, but all PhD programs do,” Manns notes. “Dissertation work varies by program.”

Initial coursework helps narrow down the research topic and develop it into something that will add to the body of knowledge in the chosen field. Sometimes the research contributes something entirely new to the field, and other times it expands or deepens previous studies.

By the time the doctoral coursework is finished, the topic should be selected and ready for formal research. At this point the student develops a proposal, which encompasses the research plan and methodology as it pertains to the selected topic.

At Capella, once the proposal has been approved by the student’s mentor, committee, and the Institutional Review Board (IRB), the research and analysis begin. The dissertation is largely an independent project that essentially turns the student into a scholar; they’ll dive more deeply into research and writing then they have done before.

“Capella PhD candidates will be prepared for this step through their coursework and residency,” says Manns, noting that they will have learned how to approach this critical phase as part of their pre-dissertation learning.

Format of the dissertation

The dissertation is a much deeper exploration of a research topic than a traditional essay would be. It’s in the form of a book, with at least five chapters (some universities require a sixth chapter in the form of a recap of the previous chapters). Manns outlines the chapters this way:

• Overview. This is a brief look at the research question, containing a preview of the subsequent chapters.
• Literature review. The literature review is an extensive critique and synthesis of the current literature in the field.
• Methodology. This section contains details of the procedures and methods used to collect and analyze data.
• Analysis. The PhD candidate details how the data analysis applies to the collected data.
• Findings. This section provides interpretation of the data and comparison to existing literature, as well as future research possibilities.

The order of the chapters follows a logical progression in which PhD candidates build on their theories and explain research choices in detail before coming to the final chapter that gives weight to the value of the study itself.

Manns recommends that pre-dissertation students review completed dissertations in the field and research various types of methodology and design in the field as well. “That will help give them a feel for the depth of research and discussion, and see how the chapters work together,” Manns explains. “And remember—someday, it may be your dissertation being read!”

Capella University offers PhD and professional doctoral degrees in programs ranging from business to education and health to technology. Learn more about Capella’s doctoral programs.

What Exactly Is A Dissertation (Or Thesis)?

If you’ve landed on this article, chances are you’ve got a dissertation or thesis project coming up (hopefully it’s not due next week!), and you’re now asking yourself the classic question, “what the #%#%^ is a dissertation?”…

In this post, I’ll break down the basics of exactly what a dissertation is, in plain language. No ivory tower academia.

So, let’s get to the pressing question – what is a dissertation?

A dissertation (or thesis) = a research project

Simply put, a dissertation (or thesis – depending on which country you’re studying in) is a research project . In other words, your task is to ask a research question (or set of questions) and then set about finding the answer(s). Simple enough, right?

Well, the catch is that you’ve got to undertake this research project in an academic fashion , and there’s a wealth of academic language that makes it all (look) rather confusing (thanks, academia). However, at its core, a dissertation is about undertaking research (investigating something). This is really important to understand, because the key skill that your university is trying to develop in you (and will be testing you on) is your ability to undertake research in a well-structured structured, critical and academically rigorous way.

This research-centric focus is significantly different from assignments or essays, where the main concern is whether you can understand and apply the prescribed module theory. I’ll explain some other key differences between dissertations or theses and assignments a bit later in this article, but for now, let’s dig a little deeper into what a dissertation is.

A dissertation (or thesis) is a process.

Okay, so now that you understand that a dissertation is a research project (which is testing your ability to undertake quality research), let’s go a little deeper into what that means in practical terms.

The best way to understand a dissertation is to view it as a process – more specifically a research process (it is a research project, after all). This process involves four essential steps, which I’ll discuss below.

Step 1 – You identify a worthy research question

The very first step of the research process is to find a meaningful research question, or a set of questions. In other words, you need to find a suitable topic for investigation. Since a dissertation is all about research, identifying the key question(s) is the critical first step. Here’s an example of a well-defined research question:

“Which factors cultivate or erode customer trust in UK-based life insurance brokers?”

This clearly defined question sets the direction of the research . From the question alone, you can understand exactly what the outcome of the research might look like – i.e. a set of findings about which factors help brokers develop customer trust, and which factors negatively impact trust.

But how on earth do I find a suitable research question, you ask? Don’t worry about this right now – when you’re ready, you can read our article about finding a dissertation topic . However, right now, the important thing to understand is that the first step in the dissertation process is identifying the key research question(s). Without a clear question, you cannot move forward.

Step 2 – You review the existing research

Once the research question is clearly established, the next step is to review the existing research/literature (both academic and professional/industry) to understand what has already been said with regard to the question. In academic speak, this is called a literature review .

This step is critically important as, in all likelihood, someone else has asked a similar question to yours, and therefore you can build on the work of others . Good academic research is not about reinventing the wheel or starting from scratch – it’s about familiarising yourself with the current state of knowledge, and then using that as your basis for further research.

Simply put, the first step to answering your research question is to look at what other researchers have to say about it. Sometimes this will lead you to change your research question or direction slightly (for example, if the existing research already provides a comprehensive answer). Don’t stress – this is completely acceptable and a normal part of the research process.

Step 3 – You carry out your own research

Once you’ve got a decent understanding of the existing state of knowledge, you will carry out your own research by collecting and analysing the relevant data. This could take to form of primary research (collecting your own fresh data), secondary research (synthesising existing data) or both, depending on the nature of your degree, research question(s) and even your university’s specific requirements.

Exactly what data you collect and how you go about analysing it depends largely on the research question(s) you are asking, but very often you will take either a qualitative approach (e.g. interviews or focus groups) or a quantitative approach (e.g. online surveys). In other words, your research approach can be words-based, numbers-based, or both . Don’t let the terminology scare you and don’t worry about these technical details for now – we’ll explain research methodology in later posts .

Step 4 – You develop answers to your research question(s)

Combining your understanding of the existing research (Step 2) with the findings from your own original research (Step 3), you then (attempt to) answer your original research question (s). The process of asking, investigating and then answering has gone full circle.

Of course, your research won’t always provide rock-solid answers to your original questions, and indeed you might find that your findings spur new questions altogether. Don’t worry – this is completely acceptable and is a natural part of the research process.

So, to recap, a dissertation is best understood as a research process, where you are:

• Ask a meaningful research question(s)
• Carry out the research (both existing research and your own)
• Analyse the results to develop an answer to your original research question(s).

Depending on your specific degree and the way your university designs its coursework, you might be asking yourself “but isn’t this just a longer version of a normal assignment?”. Well, it’s quite possible that your previous assignments required a similar research process, but there are some key differences you need to be aware of, which I’ll explain next.

Same same, but different…

While there are, naturally, similarities between dissertations/theses and assignments, its important to understand the differences  so that you approach your dissertation with the right mindset and focus your energy on the right things. Here, I’ll discuss four ways in which writing a dissertation differs substantially from assignments and essays, and why this matters.

Difference #1 – You must decide (and live with) the direction.

Unlike assignments or essays, where the general topic is determined for you, for your dissertation, you will (typically) be the one who decides on your research questions and overall direction. This means that you will need to:

• Find a suitable research question (or set of questions)
• Justify why its worth investigating (in the form of a research proposal )
• Find all the relevant existing research and familiarise yourself with the theory

This is very different from assignments, where the theory is given to you on a platter, and the direction is largely pre-defined. Therefore, before you start the dissertation process, you need to understand the basics of academic research, how to find a suitable research topic and how to source the relevant literature.

Difference #2 – It’s a long project, and you’re on your own.

A dissertation is a long journey, at least compared to assignments. Typically, you will spend 3 – 6 months writing around 15,000 – 25,000 words (for Masters-level, much more for PhD) on just one subject. Therefore, successfully completing your dissertation requires a substantial amount of stamina .

To make it even more challenging, your classmates will not be researching the same thing as you are, so you have limited support, other than your supervisor (who may be very busy). This can make it quite a lonely journey . Therefore, you need a lot of self-discipline and self-direction in order to see it through to the end. You should also try to build a support network of people who can help you through the process (perhaps alumni, faculty or a private coach ).

Difference #3 – They’re testing research skills.

We touched on this earlier. Unlike assignments or essays, where the markers are assessing your ability to understand and apply the theories, models and frameworks that they provide you with, your dissertation will be is assessing your ability to undertake high-quality research in an academically rigorous manner.

Of course, your ability to understand the relevant theory (i.e. within your literature review) is still very important, but this is only one piece of the research skills puzzle. You need to demonstrate the full spectrum of research skills.

It’s important to note that your research does not need to be ground-breaking, revolutionary or world-changing – that is not what the markers are assessing. They are assessing whether you can apply well-established research principles and skills to a worthwhile topic of enquiry. Don’t feel like you need to solve the world’s major problems. It’s simply not going to happen (you’re a first-time researcher, after all) – and doesn’t need to happen in order to earn good marks.

Difference #4 – Your focus needs to be narrow and deep.

In your assignments, you were likely encouraged to take a broad, interconnected, high-level view of the theory and connect as many different ideas and concepts as possible. In your dissertation, however, you typically need to narrow your focus and go deep into one particular topic. Think about the research question we looked at earlier:

The focus is intentionally very narrow – specifically the focus is on:

• The UK only – no other countries are being considered.
• Life insurance brokers only – not financial services, not vehicle insurance, not medical insurance, etc.
• Customer trust only – not reputation, not customer loyalty, not employee trust, supplier trust, etc.

By keeping the focus narrow, you enable yourself to deeply probe whichever topic you choose – and this depth is essential for earning good marks. Importantly, ringfencing your focus doesn’t mean ignoring the connections to other topics – you should still acknowledge all the linkages, but don’t get distracted – stay focused on the research question(s).

So, as you can see, a dissertation is more than just an extended assignment or essay. It’s a unique research project that you (and only you) must lead from start to finish. The good news is that, if done right, completing your dissertation will equip you with strong research skills, which you will most certainly use in the future, regardless of whether you follow an academic or professional path.

Wrapping up

Hopefully in this post, I’ve answered your key question, “what is a dissertation?”, at least at a big picture-level. To recap on the key points:

• A dissertation is simply a structured research project .
• It’s useful to view a dissertation as a process involving asking a question, undertaking research and then answering that question.
• First and foremost, your marker(s) will be assessing your research skills , so its essential that you focus on producing a rigorous, academically sound piece of work (as opposed to changing the world or making a scientific breakthrough).
• While there are similarities, a dissertation is different from assignments and essays in multiple ways. It’s important to understand these differences if you want to produce a quality dissertation.

In this post, I’ve gently touched on some of the intricacies of the dissertation, including research questions, data types and research methodologies. Be sure to check out the Grad Coach Blog  for more detailed discussion of these areas.

What Is a Dissertation? | 5 Essential Questions to Get Started

Published on 26 March 2020 by Jack Caulfield . Revised on 5 May 2022.

A dissertation is a large research project undertaken at the end of a degree. It involves in-depth consideration of a problem or question chosen by the student. It is usually the largest (and final) piece of written work produced during a degree.

The length and structure of a dissertation vary widely depending on the level and field of study. However, there are some key questions that can help you understand the requirements and get started on your dissertation project.

Table of contents

When and why do you have to write a dissertation, who will supervise your dissertation, what type of research will you do, how should your dissertation be structured, what formatting and referencing rules do you have to follow, frequently asked questions about dissertations.

A dissertation, sometimes called a thesis, comes at the end of an undergraduate or postgraduate degree. It is a larger project than the other essays you’ve written, requiring a higher word count and a greater depth of research.

You’ll generally work on your dissertation during the final year of your degree, over a longer period than you would take for a standard essay . For example, the dissertation might be your main focus for the last six months of your degree.

Why is the dissertation important?

The dissertation is a test of your capacity for independent research. You are given a lot of autonomy in writing your dissertation: you come up with your own ideas, conduct your own research, and write and structure the text by yourself.

This means that it is an important preparation for your future, whether you continue in academia or not: it teaches you to manage your own time, generate original ideas, and work independently.

During the planning and writing of your dissertation, you’ll work with a supervisor from your department. The supervisor’s job is to give you feedback and advice throughout the process.

The dissertation supervisor is often assigned by the department, but you might be allowed to indicate preferences or approach potential supervisors. If so, try to pick someone who is familiar with your chosen topic, whom you get along with on a personal level, and whose feedback you’ve found useful in the past.

How will your supervisor help you?

Your supervisor is there to guide you through the dissertation project, but you’re still working independently. They can give feedback on your ideas, but not come up with ideas for you.

You may need to take the initiative to request an initial meeting with your supervisor. Then you can plan out your future meetings and set reasonable deadlines for things like completion of data collection, a structure outline, a first chapter, a first draft, and so on.

Make sure to prepare in advance for your meetings. Formulate your ideas as fully as you can, and determine where exactly you’re having difficulties so you can ask your supervisor for specific advice.

Your approach to your dissertation will vary depending on your field of study. The first thing to consider is whether you will do empirical research , which involves collecting original data, or non-empirical research , which involves analysing sources.

Empirical dissertations (sciences)

An empirical dissertation focuses on collecting and analysing original data. You’ll usually write this type of dissertation if you are studying a subject in the sciences or social sciences.

• What are airline workers’ attitudes towards the challenges posed for their industry by climate change?
• How effective is cognitive behavioural therapy in treating depression in young adults?
• What are the short-term health effects of switching from smoking cigarettes to e-cigarettes?

There are many different empirical research methods you can use to answer these questions – for example, experiments , observations, surveys , and interviews.

When doing empirical research, you need to consider things like the variables you will investigate, the reliability and validity of your measurements, and your sampling method . The aim is to produce robust, reproducible scientific knowledge.

Non-empirical dissertations (arts and humanities)

A non-empirical dissertation works with existing research or other texts, presenting original analysis, critique and argumentation, but no original data. This approach is typical of arts and humanities subjects.

• What attitudes did commentators in the British press take towards the French Revolution in 1789–1792?
• How do the themes of gender and inheritance intersect in Shakespeare’s Macbeth ?
• How did Plato’s Republic and Thomas More’s Utopia influence nineteenth century utopian socialist thought?

The first steps in this type of dissertation are to decide on your topic and begin collecting your primary and secondary sources .

Primary sources are the direct objects of your research. They give you first-hand evidence about your subject. Examples of primary sources include novels, artworks and historical documents.

Secondary sources provide information that informs your analysis. They describe, interpret, or evaluate information from primary sources. For example, you might consider previous analyses of the novel or author you are working on, or theoretical texts that you plan to apply to your primary sources.

Dissertations are divided into chapters and sections. Empirical dissertations usually follow a standard structure, while non-empirical dissertations are more flexible.

Structure of an empirical dissertation

Empirical dissertations generally include these chapters:

• Introduction : An explanation of your topic and the research question(s) you want to answer.
• Literature review : A survey and evaluation of previous research on your topic.
• Methodology : An explanation of how you collected and analysed your data.
• Results : A brief description of what you found.
• Discussion : Interpretation of what these results reveal.
• Conclusion : Answers to your research question(s) and summary of what your findings contribute to knowledge in your field.

Sometimes the order or naming of chapters might be slightly different, but all of the above information must be included in order to produce thorough, valid scientific research.

Other dissertation structures

If your dissertation doesn’t involve data collection, your structure is more flexible. You can think of it like an extended essay – the text should be logically organised in a way that serves your argument:

• Introduction: An explanation of your topic and the question(s) you want to answer.
• Main body: The development of your analysis, usually divided into 2–4 chapters.
• Conclusion: Answers to your research question(s) and summary of what your analysis contributes to knowledge in your field.

The chapters of the main body can be organised around different themes, time periods, or texts. Below you can see some example structures for dissertations in different subjects.

• Political philosophy

This example, on the topic of the British press’s coverage of the French Revolution, shows how you might structure each chapter around a specific theme.

This example, on the topic of Plato’s and More’s influences on utopian socialist thought, shows a different approach to dividing the chapters by theme.

This example, a master’s dissertation on the topic of how writers respond to persecution, shows how you can also use section headings within each chapter. Each of the three chapters deals with a specific text, while the sections are organised thematically.

Like other academic texts, it’s important that your dissertation follows the formatting guidelines set out by your university. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

Formatting guidelines concern things like:

• line spacing
• page numbers
• punctuation
• title pages
• presentation of tables and figures

If you’re unsure about the formatting requirements, check with your supervisor or department. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

How will you reference your sources?

Referencing means properly listing the sources you cite and refer to in your dissertation, so that the reader can find them. This avoids plagiarism by acknowledging where you’ve used the work of others.

Keep track of everything you read as you prepare your dissertation. The key information to note down for a reference is:

• The publication date
• Page numbers for the parts you refer to (especially when using direct quotes)

Different referencing styles each have their own specific rules for how to reference. The most commonly used styles in UK universities are listed below.

You can use the free APA Reference Generator to automatically create and store your references.

The words ‘ dissertation ’ and ‘thesis’ both refer to a large written research project undertaken to complete a degree, but they are used differently depending on the country:

• In the UK, you write a dissertation at the end of a bachelor’s or master’s degree, and you write a thesis to complete a PhD.
• In the US, it’s the other way around: you may write a thesis at the end of a bachelor’s or master’s degree, and you write a dissertation to complete a PhD.

The main difference is in terms of scale – a dissertation is usually much longer than the other essays you complete during your degree.

Another key difference is that you are given much more independence when working on a dissertation. You choose your own dissertation topic , and you have to conduct the research and write the dissertation yourself (with some assistance from your supervisor).

Dissertation word counts vary widely across different fields, institutions, and levels of education:

• An undergraduate dissertation is typically 8,000–15,000 words
• A master’s dissertation is typically 12,000–50,000 words
• A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

At the bachelor’s and master’s levels, the dissertation is usually the main focus of your final year. You might work on it (alongside other classes) for the entirety of the final year, or for the last six months. This includes formulating an idea, doing the research, and writing up.

A PhD thesis takes a longer time, as the thesis is the main focus of the degree. A PhD thesis might be being formulated and worked on for the whole four years of the degree program. The writing process alone can take around 18 months.

Guide to writing your thesis/dissertation, definition of dissertation and thesis.

The dissertation or thesis is a scholarly treatise that substantiates a specific point of view as a result of original research that is conducted by students during their graduate study. At Cornell, the thesis is a requirement for the receipt of the M.A. and M.S. degrees and some professional master’s degrees. The dissertation is a requirement of the Ph.D. degree.

Formatting Requirement and Standards

The Graduate School sets the minimum format for your thesis or dissertation, while you, your special committee, and your advisor/chair decide upon the content and length. Grammar, punctuation, spelling, and other mechanical issues are your sole responsibility. Generally, the thesis and dissertation should conform to the standards of leading academic journals in your field. The Graduate School does not monitor the thesis or dissertation for mechanics, content, or style.

“Papers Option” Dissertation or Thesis

A “papers option” is available only to students in certain fields, which are listed on the Fields Permitting the Use of Papers Option page , or by approved petition. If you choose the papers option, your dissertation or thesis is organized as a series of relatively independent chapters or papers that you have submitted or will be submitting to journals in the field. You must be the only author or the first author of the papers to be used in the dissertation. The papers-option dissertation or thesis must meet all format and submission requirements, and a singular referencing convention must be used throughout.

ProQuest Electronic Submissions

The dissertation and thesis become permanent records of your original research, and in the case of doctoral research, the Graduate School requires publication of the dissertation and abstract in its original form. All Cornell master’s theses and doctoral dissertations require an electronic submission through ProQuest, which fills orders for paper or digital copies of the thesis and dissertation and makes a digital version available online via their subscription database, ProQuest Dissertations & Theses . For master’s theses, only the abstract is available. ProQuest provides worldwide distribution of your work from the master copy. You retain control over your dissertation and are free to grant publishing rights as you see fit. The formatting requirements contained in this guide meet all ProQuest specifications.

Copies of Dissertation and Thesis

Copies of Ph.D. dissertations and master’s theses are also uploaded in PDF format to the Cornell Library Repository, eCommons . A print copy of each master’s thesis and doctoral dissertation is submitted to Cornell University Library by ProQuest.

• What Is a PhD Thesis?
• Doing a PhD

This page will explain what a PhD thesis is and offer advice on how to write a good thesis, from outlining the typical structure to guiding you through the referencing. A summary of this page is as follows:

• A PhD thesis is a concentrated piece of original research which must be carried out by all PhD students in order to successfully earn their doctoral degree.
• The fundamental purpose of a thesis is to explain the conclusion that has been reached as a result of undertaking the research project.
• The typical PhD thesis structure will contain four chapters of original work sandwiched between a literature review chapter and a concluding chapter.
• There is no universal rule for the length of a thesis, but general guidelines set the word count between 70,000 to 100,000 words .

What Is a Thesis?

A thesis is the main output of a PhD as it explains your workflow in reaching the conclusions you have come to in undertaking the research project. As a result, much of the content of your thesis will be based around your chapters of original work.

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. As such, you can’t rely on other ideas or results to produce your thesis; it needs to be an original piece of text that belongs to you and you alone.

What Should a Thesis Include?

Although each thesis will be unique, they will all follow the same general format. To demonstrate this, we’ve put together an example structure of a PhD thesis and explained what you should include in each section below.

Acknowledgements

This is a personal section which you may or may not choose to include. The vast majority of students include it, giving both gratitude and recognition to their supervisor, university, sponsor/funder and anyone else who has supported them along the way.

Provide a brief overview of your reason for carrying out your research project and what you hope to achieve by undertaking it. Following this, explain the structure of your thesis to give the reader context for what he or she is about to read.

2. Literature Review

Set the context of your research by explaining the foundation of what is currently known within your field of research, what recent developments have occurred, and where the gaps in knowledge are. You should conclude the literature review by outlining the overarching aims and objectives of the research project.

3. Main Body

This section focuses on explaining all aspects of your original research and so will form the bulk of your thesis. Typically, this section will contain four chapters covering the below:

• your research/data collection methodologies,
• your results,
• a comprehensive analysis of your results,
• a detailed discussion of your findings.

Depending on your project, each of your chapters may independently contain the structure listed above or in some projects, each chapter could be focussed entirely on one aspect (e.g. a standalone results chapter). Ideally, each of these chapters should be formatted such that they could be translated into papers for submission to peer-reviewed journals. Therefore, following your PhD, you should be able to submit papers for peer-review by reusing content you have already produced.

4. Conclusion

The conclusion will be a summary of your key findings with emphasis placed on the new contributions you have made to your field.

When producing your conclusion, it’s imperative that you relate it back to your original research aims, objectives and hypotheses. Make sure you have answered your original question.

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

How Many Words Is a PhD Thesis?

A common question we receive from students is – “how long should my thesis be?“.

Every university has different guidelines on this matter, therefore, consult with your university to get an understanding of their full requirements. Generally speaking, most supervisors will suggest somewhere between 70,000 and 100,000 words . This usually corresponds to somewhere between 250 – 350 pages .

We must stress that this is flexible, and it is important not to focus solely on the length of your thesis, but rather the quality.

How Do I Format My Thesis?

Although the exact formatting requirements will vary depending on the university, the typical formatting policies adopted by most universities are:

What Happens When I Finish My Thesis?

After you have submitted your thesis, you will attend a viva . A viva is an interview-style examination during which you are required to defend your thesis and answer questions on it. The aim of the viva is to convince your examiners that your work is of the level required for a doctoral degree. It is one of the last steps in the PhD process and arguably one of the most daunting!

For more information on the viva process and for tips on how to confidently pass it, please refer to our in-depth PhD Viva Guide .

How Do I Publish My Thesis?

Unfortunately, you can’t publish your thesis in its entirety in a journal. However, universities can make it available for others to read through their library system.

If you want to submit your work in a journal, you will need to develop it into one or more peer-reviewed papers. This will largely involve reformatting, condensing and tailoring it to meet the standards of the journal you are targeting.

A dissertation, also known as a doctoral thesis , is the final required part of completing a student's doctoral study. Undertaken after a student completes coursework and passes a comprehensive examination , the dissertation is the final hurdle in completing a Ph.D. or other doctoral degree. The dissertation is expected to make a new and creative contribution to a field of study and to demonstrate the student's expertise. In social science and science programs, the dissertation usually requires conducting empirical research.

Elements of a Strong Dissertation

According to the Association of American Medical Colleges, a strong medical dissertation relies heavily on the creation of a specific hypothesis that can be either disproven or supported by data collected by independent student research. Further, it must also contain several key elements starting with an introduction to the problem statement, conceptual framework and research question as well as references to literature on already published on the topic. 

A dissertation must also be relevant (and proven to be such) as well as capable of being researched independently by the student. Though the required length of these dissertations varies by school, the governing body overseeing the practice of medicine in the United States standardizes this same protocol. Also included in the dissertation is the methodology for research and data collection as well as instrumentation and quality control. A stated section on population and sample size for the study is imperative to defending the thesis once it comes time to do so.

Like most scientific publications, the thesis must also contain a section of published results and an analysis of what this entails for the scientific or medical community. The discussion and conclusion sections let the review committee know that the student understands the full implications of his or her work as well as its real-world application to their field of study (and soon, professional work). 

Approval Process

Although students are expected to conduct the bulk of their research and pen the entire dissertation on their own, most graduate medical programs provide an advisory and review committee to the student upon starting their studies. Through a series of weekly reviews over their course of schooling, the student and his or her advisor hone in on the hypothesis of the dissertation before they submit it to the review committee to begin work on writing the thesis. 

From there, the student can take as long or as short of a time as they need to complete their dissertation, often resulting in students who have finished their entire courseload achieving ABD status ("all but dissertation"), just shy of receiving their full Ph.D. In this interim period, the student — with the occasional guidance of his or her advisor —  is expected to research, test and write a dissertation that can be defended in a public forum. 

Once the review committee accepts the finalized draft of the thesis, the doctoral candidate will then get the chance to publicly defend his or her statements. If they pass this test, the dissertation is submitted electronically to the school's academic journal or archive and the candidate's full doctoral degree is issued once the final paperwork has been submitted.

What is a Ph.D. Dissertation?

[I wrote this in 1993 as a letter to a student concerning a draft of his dissertation. In 2003 I edited it to remove some specific references to the student and present it as a small increment to the information available to my grad students. In 2023 I made small edits for grammar and to expand coverage.--spaf]

Let me start by reviewing some things that may seem obvious:

• Your dissertation is part of the requirements for a PhD. The research, theory, experimentation, et al. also contribute. One does not attempt to capture everything in one's dissertation.
• The dissertation is a technical work that documents and proves one's thesis. It is intended for a technical audience and must be clear and complete but not necessarily exhaustively comprehensive. Also note -- experimental data, if used, is not the proof -- it is evidence. The proof is presented as an analysis and critical presentation. Generally, every statement in your dissertation must be common knowledge, supported by citation to technical literature, or original results proved by the candidate (you). Each of those statements must directly relate to the proof of the thesis, or else they are unnecessary.

Let's revisit the idea of the thesis itself. It is a hypothesis, a conjecture, or a theorem. The dissertation is a formal, stylized document used to argue your thesis. The thesis must be significant, original (no one has yet demonstrated it to be true), and it must extend the state of scientific knowledge.

The first thing you need to do is to come up with no more than three sentences that express your thesis. Your committee must agree that your statements form a valid thesis statement. You, too, must be happy with the statement -- it should be what you will tell anyone if they ask you what your thesis is (few people will want to hear an hour's presentation as a response).

Once you have a thesis statement, you can begin developing the dissertation. The abstract, for instance, should be a one-page description of your thesis and how you present the proof of it. The abstract should summarize the results of the thesis and should stress the contributions to science made thereby.

Perhaps the best way to understand how an abstract should look would be to examine the abstracts of several dozen dissertations that have already been accepted. Our university library has a collection of them. This is a good approach to see how an entire dissertation is structured and presented. MIT Press has published the ACM doctoral dissertation award series for decades, so you may find some of those to be good examples to read -- they should be in any large technical library.

The dissertation itself should be structured into 4 to 6 chapters. The following is one commonly-used structure:

• Introduction. Provide an introduction to the basic terminology, cite appropriate background work, and briefly discuss related work that has already covered aspects of the problem.
• Abstract model. Discuss an abstract model of what you are trying to prove. This chapter should not discuss any specific implementation (see below)
• Validation of model/proof of theorems. This is a chapter showing proof of the model. It could be a set of proofs or a discussion of the construction and validation of a model or simulation to gather supporting data.
• Measurements/data. This would present data collected from actual use, simulations, or other sources. The presentation would include analysis to show support for the underlying thesis.
• Additional results. In some work, there may be secondary confirmation studies, or it might be the case that additional significant results are collected along the way to the proof of the central thesis. These would be presented here.
• Conclusions and future work. This is where the results are all tied together and presented. Limitations, restrictions, and special cases should be clearly stated here, along with the results. Some extensions as future work may also be described.

Let's look at these in a little more detail

Chapter I, Introduction. Here, you should clearly state the thesis and its importance. This is also where you define terms and other concepts used elsewhere. There is no need to write 80 pages of background on your topic here. Instead, you can cover almost everything by saying: "The terminology used in this work matches the definitions given in [citation, citation] unless noted otherwise." Then, cite some appropriate works that give the definitions you need. The progress of science is that we learn and use the work of others (with appropriate credit). Assume you have a technically literate readership familiar with (or able to find) standard references. Do not reference popular literature or WWW sites if you can help it (this is a matter of style more than anything else -- you want to cite articles in refereed conferences and journals, if possible, or in other theses).

Also, in the introduction, you want to survey any related work that attempted something similar to your own or has a significant supporting role in your research. This should refer only to published references. You cite the work in the references, not the researchers themselves. E.g., "The experiments described in [citation] explored the foo and bar conditions, but did not discuss the further problem of baz, the central point of this work." You should not make references such as this: "Curly, Moe, and Larry all believed the same in their research [CML53]" because you do not know what they believed or thought -- you only know what the paper states. Every factual statement you make must have a specific citation tied to it in this chapter, or else it must be common knowledge (don't rely on this too much).

Chapter II. Abstract Model. Your results are to be of lasting value. Thus, the model you develop and write about (and indeed, that you defend) should have lasting value. Thus, you should discuss a model not based on Windows, Linux, Ethernet, PCMIA, or any other technology. It should be generic and capture all the details necessary to overlay the model on likely environments. You should discuss the problems, parameters, requirements, necessary and sufficient conditions, and other factors here. Consider that 20 years ago (ca 1980), the common platform was a Vax computer running VMS or a PDP-11 running Unix version 6, yet well-crafted theses of the time are still valuable today. Will your dissertation be valuable 20+ years from now (ca 2050), or have you referred to technologies that will be of only historical interest?

This model is tough to construct but is the heart of the scientific part of your work. This is the lasting part of the contribution, and this is what someone might cite 50 years from now when we are all using MS Linux XXXXP on computers embedded in our wrists with subspace network links!

Chapters III & IV, Proof.There are basically three proof techniques that I have seen used in a computing dissertation, depending on the thesis topic. The first is analytic, where one takes the model or formulae and shows, using formal manipulations, that the model is sound and complete. A second proof method is stochastic, using statistical methods and measurements to show that something is true in the anticipated cases.

• clearly showing how your implementation model matches the conditions of your abstract model,
• describing all the variables and why you set them as you do,
• accounting for confounding factors, and
• showing the results.

Chapter V. Additional results. This may be folded into Chapter III in some theses or multiple chapters in a thesis with many parts (as in a theory-based thesis). This may be where you discuss the effects of technology change on your results. This is also a place where you may wish to point out significant results that you obtained while seeking to prove your central thesis but which are not supportive of the thesis. Often, such additional results are published in a separate paper.

Chapter VI. Conclusions and Future Work. This is where you discuss what you found from your work, incidental ideas and results that were not central to your thesis but of value nonetheless (if you did not have them in Chapter V), and other results. This chapter should summarize all the important results of the dissertation --- note that this is the only chapter many people will ever read, so it should convey all the important results.

This is also where you should outline some possible future work that can be done in the area. What are some open problems? What are some new problems? What are some significant variations open to future inquiry?

Appendices usually are present to hold mundane details that are not published elsewhere but are critical to the development of your dissertation. This includes tables of measurement results, configuration details of experimental testbeds, limited source code listings of critical routines or algorithms, etc. It is not appropriate to include lists of readings by topic, lists of commercial systems, or other material that does not directly support the proof of your thesis.

Here are some more general hints to keep in mind as you write/edit:

• Adverbs should generally not be used -- instead, use something precise. For example, do not say that something "happens quickly." How fast is quickly? Is it relative to CPU speeds? Network speeds? Does it depend on connectivity, configuration, programming language, OS release, etc? What is the standard deviation?
• As per the above, the use of the words "fast," "slow," "perfect," "soon," "ideal," "lots of," and related should all be avoided. So should "clearly," "obviously," "simple," "like," "few," "most," "large," et al.
• What you are writing is scientific fact. Judgments of aesthetics, ethics, personal preference, and the like should be in the conclusions chapter, if they should be anywhere at all. With that in mind, avoid the use of words such as "good," "bad," "best," and any similar discussion. Also, avoid stating "In fact," "Actually," "In reality," and any similar construct -- everything you are writing must be factual, so there is no need to state such things. If you feel compelled to use one of these constructs, then carefully evaluate what you are saying to ensure you are not injecting relative terms, opinions, value judgments, or other items inappropriate for a dissertation.
• Computers and networks do not have knees, so poor performance cannot bring them to something they do not have. They also don't have hands, so "On the one hand..." is not good usage. Programs don't perform conscious thought (nor do their underlying computers), so your system does not "think" that it has seen a particular type of traffic. Generalizing from this, do not anthropomorphize your IT components!
• Avoid mention of time and environment. "Today's computers" are antiques far sooner than you think. Your thesis should still be true many years from now. If a particular time or interval is necessary, be explicit, as in "Between 1905 and 1920" rather than "Over the last 15 years." (See the difference, given some distance in time?)
• Be sure that any scientist or mathematician would recognize something you claim as proof.
• Focus on the results and not the methodology. The methodology should be clearly described but not the central topic of your discussion in chapters III & IV
• Keep concepts and instances separate. An algorithm is not the same as a program that implements it. A protocol is not the same as the realization of it; a reference model is not the same as a working example, and so on.

As a rule of thumb, a CS dissertation should probably be longer than 100 pages but less than 160. Anything outside that range should be carefully examined with the above points in mind.

Keep in mind that you -- the Ph.D. candidate -- are expected to become the world's foremost expert on your topic area. That topic area should not be unduly broad but must be big enough to be meaningful. Your advisor and committee members are not supposed to know more about the topic than you do -- not individually, at least. Your dissertation is supposed to explain your findings and, along with the defense, demonstrate your mastery of the area in which you are now the leading expert. That does not mean writing everything you know -- it means writing enough about the most important points that others can agree with your conclusions.

Last of all, don't fall into the trap that ties up many candidates and causes some of them to flame out before completion: your thesis does not need to be revolutionary. It simply needs to be an incremental advancement in the field. Few Ph.D. dissertations have ever had a marked impact on the field. Instead, it is the author's set of publications and products of the author that may change the field.

If your dissertation is like most, it will only be read by your committee and some other Ph.D. candidates seeking to build on your work. As such, it does not need to be a masterwork of literature, nor does it need to solve a long-standing problem in computing. It merely needs to be correct, to be significant in the judgment of your committee, and it needs to be complete. We will all applaud when you change the world after graduation. And at that, you will find that many well-known scientists in CS have made their careers in areas different from their dissertation topic. The dissertation is proof that you can find and present original results; your career and life after graduation will demonstrate the other concerns you might have about making an impact.

Dissertation 101: Tips for researching and writing a doctoral dissertation

By Elizabeth Exline

When Rose Lorenzo got close to finishing her  master’s degree  at University of Phoenix (UOPX), she came to a crossroads. She could walk away with her degree and focus on building her company,  Lorenzo Financial , or she could scratch the itch for more academic knowledge and pursue her doctorate.

Lorenzo chose the latter. (And  still  managed to build her company, lay the groundwork to  launch a new school  and eventually get accepted to law school.)

“Although I knew what I wanted to study, I wish I had known how to choose the right topic and how to narrow that topic down before I started,” Lorenzo recalls.

Lorenzo, of course, is talking about the  dissertation , that book-length document that’s both the capstone of the doctoral degree and the driving force behind a doctoral program’s years of study and academic research.

But settling on a topic is just one part of a process that can intimidate even the most determined scholar. What’s exactly involved in a dissertation? And what’s the point of one anyway? Here, we take a deeper dive into the dissertation experience.

What is a dissertation?

A dissertation is an academic document prepared by a doctoral student that contains  original research  about a topic. The student identifies the  topic, conducts the research, writes the dissertation and defends it in front of a committee led by a dissertation chair and other doctoral faculty who decide whether the research meets the doctoral level research standards. If it does, the student will successfully complete the doctoral program, have their dissertation published in ProQuest and earn a terminal degree , which means the highest education level that can be earned in a field.

The dissertation, in other words, is important. But why all the fuss in the first place? According to Rodney Luster, PhD, a dissertation can enhance society’s overall  knowledge and understanding about an issue and ignite a person’s area of interest and expertise, as well as enhance that expertise .

Luster is the chair for the Center for Leadership Studies and Organizational Research within the College of Doctoral Studies at University of Phoenix , and he points to his own dissertation by way of example. 

His research concerned what is currently known as vicarious trauma, a phenomenon he witnessed among his college students after the 9/11 attacks. His students hadn’t been anywhere near the attack, and yet he noticed they displayed classic signs of trauma. This piqued his interest.

“I was able to conduct what I understand was the first research study looking at  vicarious trauma  in the general population, and that has opened up a lot of doors,” Luster explains.

Now an expert on the concept, he has seen the phenomenon after subsequent events, such as Hurricane Katrina.

Lorenzo’s research was more tailored to her area of interest. She ultimately whittled down her topic from how leadership impacts entrepreneurial success or failure to how it impacts female entrepreneurs specifically.

Topics, in other words, offer the freedom for students to follow their curiosity and experience with the goal of potentially  solving a problem  or  adding to a field’s body of knowledge .

Practitioner doctorate vs. PhD – 5 things to know before getting started

Dissertation vs. thesis — what's the difference.

Some people may confuse a dissertation with a thesis, but they’re not the same thing. While similar in nature in that they are both the capstone of an academic program, the biggest difference is where a dissertation and a thesis fit in the educational journey. As explained, a doctoral student completes a dissertation, while a thesis is a research paper for a master’s-level student or sometimes within a bachelor’s program. 

There are other differences as well. One is the level of research involved. Often, a thesis is based on existing research. This means that an undergrad or graduate student will compile various research findings to defend a theory or idea in a thesis. A dissertation on the other hand requires doctoral students to conduct, present and defend their own research.

The two documents differ in length too. A thesis is often much shorter and can range from 40 to 60 pages for an undergraduate thesis and from 60 to upward of 100 pages for a master's thesis. A dissertation is 150 to 300 pages, or 80,000 to 100,000 words. As noted, whether it’s presented in front of a panel of faculty or academics as an oral defense is another key difference. This is often required for a dissertation, but oral defense of a thesis may depend on the program or institution.

How to write a dissertation

Figuring out a dissertation topic is a process as individualized as the students in a doctoral degree program. Luster usually encourages candidates to  begin with a title .

“That’s going to be your selling point for everything, and it has to be understandable. It must be concise. It must have a theoretical construct in it. The title will take you a lot of places and will help lead you into the writing process.”

To this Lorenzo adds a less lofty but equally valid cross-check: She learned to really drill down any topic with the question, “ Who cares? ” If there are people who are invested in learning more about the topic (if there are, in other words, people who care), it may warrant further research.

These preliminary exercises lay a solid foundation for the dissertation process, but the actual research and writing can still feel intimidating. Luster, for example, had written a book before starting his dissertation, and points out that a dissertation “is not like any other writing that you’ve done.”

So, where do you start? At UOPX, you start in your first class.

Understanding ACCESS

The dissertation process at UOPX was revamped and rolled out in September 2019, notes Shawn C. Todd-Boone, EdD, the associate dean for ACCESS, research and residency at the College of Doctoral Studies.

Luster says the process was reimagined based on extensive feedback and on a desire to make the process more effective and efficient.

One of the first ways the dissertation process changed was with the development of  ACCESS , an acronym for “ advancing community, critical thought, engagement, scholarship and success .”

This sequence is incorporated into the first three interdisciplinary courses of any doctoral program at UOPX with an eye toward introducing doctoral candidates to what Luster calls a “theoretical mindset.”

The ACCESS program attempts to nurture a culture of inquiry that helps retain doctoral candidates while inspiring them to innovate in their fields, Boone says.

ACCESS, in other words, sets the tone for the entire doctoral process, which is founded on innovation, research and critical thinking.

The five phases of the dissertation

Writing the dissertation occurs in what Luster describes as five phases over the course of different classes. These are:

• Phase 1: Develop a  prospectus , which is an outline of the research project.
• Phase 2: Draft the first chapter of the dissertation, which is known as the  précis .
• Phase 3: Undergo a  concept review  and develop the second chapter.
• Phase 4: Focus on the  proposal , write the third chapter and review chapters one through three.
• Phase 5: Obtain the approval of the  Institutional Review Board , which evaluates research according to the University’s ethical standards.

The uopx difference.

The five phases of the dissertation writing process aren’t ubiquitous. Doctoral students work on a dissertation while going through the program at UOPX — which was very much intentional, according to Boone.

“We have five phases in the dissertation process and a deliverable at the end of each phase to encourage students to finish and to complete on time if they commit to the process,” Boone explains.

This is a notable improvement, according to Lorenzo. “It is more effective to start your research on day one than wait, because it's easier to identify the gap in research and eliminate wasted research time on topics that are not relevant to your study, and [it] helps contribute to the literature review of the study,” she says.

But this process isn’t the only benefit UOPX students enjoy. The doctoral program has several other distinctive features:

• Once upon a time, students interviewed potential research chairs to take on the oversight of their program. The result was stressful, with doctoral candidates often casting a wide net in the hope of securing a chair and then potentially ending up with someone who wasn’t quite the perfect fit. Today, UOPX takes the stress and potential mismatch out of the equation. “Students do not search for  dissertation committee members ,” Boone says. “We assign them.”
• Dissertations from UOPX tend to focus on  functional application  more so than just theory, Luster notes. This means topics have real-world applications, and communities and industries may benefit from the research. For example, one recent dissertation explored the integration of nurse graduates into hospital settings during COVID-19.
• Doctoral candidates have access to  diverse and extensive resources . In addition to comprehensive documentation about the dissertation process at UOPX, candidates can leverage one-on-one appointments with the University’s library staff, engage in workshops with research chairs and seek opportunities to work as research assistants.
• Rather than what Luster calls a sink-or-swim approach, UOPX has invested in a  mentor-driven approach . “I think that makes us largely different and successful with students, especially adult learners,” Luster says.

In the end, that sense of a safety net — both in terms of mentorship and the doctoral community itself — is one of the biggest reassurances doctoral candidates enjoy.

Lorenzo, for example, keeps in touch with a core group of colleagues she met through the program. “No one understands what you’re going through except for [your peers],” she notes.

Or, as Luster puts it: “You don’t have to worry, because you’ll acquire this information along the way, and you have a lot of good people to help you.”

How long is a doctoral dissertation?

Most are 100 to 300 pages and organized by chapters and/or sections and subsections. There are also often requirements for text size, page size and spacing that can depend on your doctoral program.

What are the parts of a dissertation?

A dissertation generally includes a Dissertation Acceptance Certificate, a title page, a copyright statement, an abstract (detailing the objective of the research, the methods and the outcome), a table of contents, the research itself and supplemental information (either as an appendix with charts and tables or as an uploaded file with digital information). Some dissertations include front and back matter, such as acknowledgments, a dedication, a glossary, a bibliography and related features.

Is a dissertation required for a doctorate?

Not always. While most doctoral and PhD degree programs require a dissertation, some don’t, and others require a capstone project.

What's the difference between a PhD and a doctorate?

Individuals who complete a PhD focus on producing new knowledge to contribute to a theory or body of research. Individuals who  complete a practitioner doctorate , on the other hand, focuses on how to apply knowledge to a field or particular issue.

What is a Dissertation? [2024 Guide]

It’s common for people who are considering a graduate degree to ask, “What is a dissertation?” This term comes up often in discussions of doctoral requirements, but it may not be immediately obvious what’s involved.

Getting the facts about dissertations can help you decide whether this is a project to which you’re ready to commit.

Editorial Listing ShortCode:

Since a doctoral dissertation can be an integral component of a PhD program, you may want to learn all about it before applying to schools.

What Is a Dissertation?

A dissertation is a major project completed by PhD candidates. Through it, you will establish yourself as an expert with the knowledge, critical thinking, and research skills to move your field of study forward.

The dissertation process usually gets into full swing after you complete your doctoral coursework. Before that, though, you may take several classes that will help you get started and teach you what steps to take.

The process of dissertation writing involves several phases. You’ll select a topic, do research, and type up a book-length paper about your findings and conclusions. Afterward, you will present a dissertation defense to a committee of experts who will evaluate your methodology and analyses.

As you work on your doctoral dissertation, you’ll receive the guidance of a faculty advisor. Additional support people may help you refine your strategies and ideas as well. This academic writing project can take many years, but a PhD will be the reward.

Types of Dissertations

It’s common to think of a dissertation as an original research project, but that’s not the only form that this major paper can take.

• Empirical Dissertation . This type of dissertation involves performing original research. You would design a research study, carry it out, and collect data. Perhaps you would conduct lab studies or speak to test subjects in focus groups. You’d then analyze the data and draw conclusions, which you’d write about in your dissertation.
• Non-Empirical Dissertation . With this approach to doing a dissertation, you study and analyze others’ research. The goal isn’t to rehash what others in your field have already said but to think critically about it. Your objective might be to identify areas where research is lacking or to suggest new ways to apply current theories.

Before you commit to one path or the other, it’s beneficial to weigh the options carefully with your faculty supervisor. Some universities now offer online doctorate programs without dissertation but have a capstone project for completion. Common programs include on campus DBA degrees or online doctoral programs in education with no dissertation requirement .

How to Write a Dissertation (From Choosing a Topic to Defending It )

Writing a dissertation is a massive undertaking, so it can help to break the process down into steps.

• Figure out your topic . The topic you choose should address a current hole in the field, captivate your interest, and provide enough material for a robust project. You should be able to distill your topic down into a single sentence, whether a statement or a question.
• Do background work . It’s necessary to familiarize yourself with the subject and how people in your field currently understand it. This may include running some preliminary tests or reading published studies.
• Craft your research proposal . Before going any further, it’s necessary to inform your faculty advisor about your plans. You’ll write a multi-page paper that outlines your topic and how you plan to address it. Your supervisor may then accept, adjust, or reject your proposal.
• Undertake the research . Once you have a plan in place, it will be time to dig into the research portion of your project. What this looks like varies from one person’s dissertation to the next and can depend largely on the field of study. You may need to do lab work, collect data from study participants, review primary source material, or gather secondary commentary on relevant studies.
• Prepare for the writing process . You may want to read through other people’s dissertations or craft an outline to help guide your process.
• Draft the body . Once you’re ready to begin, you’ll type up the first draft of your dissertation’s chapters.
• Get feedback . Throughout the process, it’s helpful to stay in touch with your advisor as well as outside support people. You can ask for their feedback and incorporate it into your work.
• Prepare the final copy . You’ll edit and proofread your work as well as add an introduction, a conclusion, the appendices, and any additional elements.
• Finish with the defense . Once you’ve completed each of the above steps, your advisor will determine whether you’re ready to defend your dissertation. You’ll present your research to a panel of experts and field their questions.

If the panel approves of your work, you’ll have successfully completed your dissertation!

Typical Chapters in a Dissertation

Writing a dissertation is different than pulling together a short research paper. Most dissertations are quite long and are broken up into chapters. The format can vary, but the following list provides an overview of common chapter breakdowns:

• Introduction . Your paper’s first main chapter will introduce the topic.
• Review of current studies . Known as a literature review, this next chapter or part gives an overview of others’ research related to this topic. It shows where there are gaps in current knowledge and demonstrates the theoretical underpinnings of your project.
• Research methodology . You will present your approach to collecting data for your research project, and you’ll also discuss your analysis methods.
• Report of results . You’ll tell readers the things you learned during your study. This is where you’ll present your data, and you may use charts or graphs to visualize your findings.
• Discussion of results . Your project is about more than simply gathering data. It’s essential to analyze the data as well. In this section, you’ll present your analysis of your findings to help readers learn what the figures mean. You can also share how these findings could advance your field.
• Conclusion . Finally, you’ll conclude by restating the purpose of your project and summarizing how you have met that objective.

Many dissertations contain other parts as well. Examples include title pages, dedication pages, glossaries, and appendices.

How Long Is a Dissertation for PhD?

Dissertations can vary in length, but they are usually at least 100 pages. Some are 300 pages or longer. Papers between 100 and 200 pages are the most common.

The standard length of a dissertation changes from one field to another. For example, history students often write dissertations that are several hundred pages. Mathematics PhD candidates may have dissertations that are fewer than 100 pages. The school where you earn your doctoral degree may set guidelines for the length of your PhD.

How Many Pages Is a Dissertation?

Many dissertations are a few hundred pages long. You’ll divide those pages up among the different sections of your paper.

The introduction may be 10 or 15 pages long. Your literature review will likely be longer—perhaps around 20 pages. Students may need up to 15 pages to explain your methodology, but the results section should be under 10 pages. Finally, students can use 15 pages or more to share their conclusions.

Dissertation lengths vary among academic disciplines. Your academic supervisor can provide specific guidance for your situation.

What’s a Dissertation Defense?

A dissertation defense is an opportunity to speak with experts from your field about your work. This step comes after you have finished the dissertation research and writing.

The committee will determine whether you have sufficiently answered your original question and contributed valuable research to your field. But you won’t present your defense until your advisor deems you ready, so the experience might not be as nerve-wracking as it sounds.

During the defense, you may give a presentation to the committee. In addition, they can ask you questions, talk to you about your work, and discuss your work among themselves.

What’s the Difference Between a Dissertation vs. Thesis?

In grad school, you’ll hear about dissertations and theses. Both are major projects, but they play different roles.

The above distinctions between a thesis vs. dissertation apply to US schools only. Other countries use different naming conventions.

Writing Your Dissertation

Choosing to enroll in a PhD program and write a dissertation is a big decision. With careful planning and steadfast dedication, you can get this job done.

In the process, you can contribute research and insights to your field and help answer important questions. Plus, you can earn a PhD, a prestigious degree that can take you far in life. PhD programs with dissertations are available from both on-campus and online graduate schools. You can select the format that best suits your schedule and preferences.

If you’re ready to get started, then now is the time to explore accredited universities.

What is a Dissertation? Undergrad, Masters & PhD

A dissertation is a long written piece of academic research completed as part of a university degree.

The dissertation will be the longest thing you write at university. It might be anywhere from:

• Shortest: 5000 words long (a baby undergraduate dissertation), up to
• Longest: 100,000 words (a PhD dissertation in the social sciences).

Your dissertation will explain the processes and results of research that you conducted. You would also write an analysis of the results and recommendations for further research.

You usually complete your dissertation at the end of your degree, so in North America you might hear people calling it the “capstone project”.

Difference between a Dissertation and Thesis

We often use the terms ‘dissertation’ and ‘thesis’ interchangeably. I’ve also read a lot of articles out there on the internet that claim that there are clear differences between the two. There aren’t.

I’ve completed an undergraduate and a doctoral dissertation. I’ve supervised well over 100 dissertation students at undergraduate, masters and PhD level. I’ve taught at universities in Europe, Australia and North America. In all my time, it’s been quite apparent to me that people use the terms interchangeably.

Now, there is also another time we use the term ‘thesis’. A thesis is also known as your main argument in an essay and/or dissertation.

So, technically, a dissertation contains a thesis . The dissertation is the written report that you can pick up and carry around. The thesis is the key argument you’re making within the written report.

But save yourself the stress of trying to differentiate between the two: in 90% of all situations, when someone says ‘dissertation’ or ‘thesis’ they mean the same thing: they just mean “that big project you’ve been working on for the past 2 years of your life and you want to throw out the window.”

What is a Dissertation Supervisor?

When you start your dissertation, you’ll be allocated a dissertation supervisor. Your supervisor will guide you through the process.

For undergraduate students, this may be the first time you’ve worked closely in a one-to-one environment with a university professor before. You’ll meet up for regular meetings and they’ll look over drafts of your work and tell you how to improve it.

The 3 Levels of Dissertation

Dissertations can be written during undergraduate and postgraduate studies. Here are the three different levels:

Honors or Undergraduate Dissertation

You may be asked to write a dissertation to get your undergraduate degree. Outside of North America, this is a requirement if you want to graduate “with honors”.

An undergraduate dissertation will range from about 5,000 to 30,000 words. Most undergraduate dissertations that I’ve come across usually come out at about 10,000 words and take their full senior to complete. However, different universities have different standards.

Undergraduate students are not usually asked to do complicated research studies. It’s an introduction to academic research, so you’re likely only going to do a small pilot study, but it’s good for learning how research happens and getting your toes wet.

You’ll also get to zoom-in on a topic of your choice, so it’s a chance to show future employers what your interests are and how you’ve pursued them at university level.

Masters Dissertation

A masters dissertation is completed by people who choose to do a masters degree “by research”. Some masters by coursework degrees don’t have a dissertation component, so you may not have to do a dissertation at all.

At masters level, you’ll need to step up your game a little. Masters-level dissertations typically range from 15,000 to 50,000 words and involve a small but rigorous research study.

Many of the masters students who I have supervised in the past have conducted case study or ‘action research’ projects where they did a study in their own workplace.

Others have done standalone studies where they’ve come up with a topic to research and gone ahead to conduct the research over about a 12 to 24 month period.

PhD Dissertation

A PhD or doctorate dissertation is the big kahuna of dissertations. If you successfully write one of these, you can call yourself ‘Doctor’ for the rest of your days (but you won’t be one of those doctors – you know, the ones with stethoscopes).

Most PhD dissertations are 80,000 to 100,000 words long – or about the length of your average novel. Now that’s a lot of words!

Your PhD absolutely has to (at a minimum) make a unique contribution to knowledge. That means you need to study something no one else has ever studied before and convince experts in the field that it was a well-done and valid study. Ideally you should also be able to tell people that you’re a world-leading expert in the topic you studied.

What is the Structure of a Dissertation?

There are many different ways you can structure your dissertation. Different disciplines have different expectations and standards.

Many of my students freak out that they have to write such long pieces of work. But, by splitting the dissertation up into sections like I have done below, they come to realize that it’s just a whole lot of short pieces all glued together to make a coherent, interesting story.

Here’s one of the most common structures that 95% of all of my students in Arts, Humanities and Social Sciences follow:

1. Introduction (10%)

The introduction gives an overview of the topic to readers and lets them know of its importance. It will introduce the reader to the research topic and the question you’re studying. It might also introduce some key terms and give an overview of the structure of the piece to come.

2. Literature Review (15 – 25%)

A literature review will give a detailed overview of everything that’s currently known about the topic. It’ll show the reader that you have deep knowledge of the topic and that you’re qualified to conduct the study.

Ideally, you’ll also use the literature review to show how your study builds upon what’s already known. You don’t want to just do a study that’s already been done, but you can learn a lot from previous studies and use their knowledge to make your work better.

3. Theoretical Framework (15 – 25%)

This section isn’t always used (you’ll probably skip it for an undergraduate dissertation), but it is common in some Masters and PhD level studies. It outlines what lens you’re using to critique concepts. Maybe you’ll use a theory like ‘grounded theory’, ‘ postmodernism ’, ‘ critical theory ’ or ‘feminist theory’ to study something from a particular perspective. You’ll need to show your reader that you have deep knowledge of that theory that you’re using, and why the theory is worth employing in your study.

If this is all too confusing to you now, never mind: you may not even need to use a theoretical framework , depending on the requirements of your course.

4. Methodology (15 – 25%)

A methodology section outlines how you will conduct your study. What methods, procedure and ethical guidelines will you use? How will you ensure your work is honest, trustworthy, reliable or accurate?

5. Results (10%)

The results section outlines what you found out. Particularly in quantitative work (that’s a study that uses methods that measure things using numbers and algorithms), you’ll have a results section separate from the analysis section. In qualitative work , often the results and analysis are blended together.

6. Analysis (15 – 25%)

The analysis is the section where you critique the results. What do the results reveal about your topic? How do your results show us something new or provide fresh insights into an old topic?

7. Conclusion (10%)

The conclusion will usually sum up what you’ve said and explain its relevance for researchers or practitioners. You will give recommendations to future researchers on what studies they might want to undertake, or you might tell practitioners how your findings could be used to improve their workplace.

Conclusions also often outline weaknesses or challenges you faced. This is important to show that you’ve reflected on your blindspots and acknowledged them. No study is perfect.

How to Conduct a Research Study for a Dissertation

You’ll have to choose a research topic, study it in depth, and conduct original research on it. It seems like a daunting task, but with your dissertation supervisor, you’ll work together to break it down into manageable chunks.

An Example: Laura’s Undergraduate Dissertation

Let’s say Laura has to write a 10,000 word undergraduate dissertation in her Education Studies degree. This would be pretty common if she wants to graduate with honors. Here’s what she might do:

1. Choose a Topic

Laura needs to choose a topic to write about. She is really interested in play-based learning , so she chose this as her topic for her dissertation.

>>>RELATED POST: 51 BEST EDUCATION DISSERTATION TOPIC IDEAS

2. Conduct a Literature Review

Laura started reading up about the topic and write a 2,500 word review of all of the literature that’s out there on play-based learning. She found a few themes in the articles she read, so she split it up into 6 sections for the 5 themes she found, with 500 words in each section.

3. Come up with a Research Question

Now that Laura has some in-depth knowledge about her topic, she’s going to have to conduct some original research of her own to prove her expertise in the topic. Usually, we ask students to do research that no one has done before so that it is unique and tells us something new about the topic. Fortunately, because she’s done her literature review, Laura will now have deep knowledge of the topic and know things about play-based learning that haven’t been researched in the past.

Let’s say Laura decided that she wanted to interview teachers about the challenges they face during play-based learning lessons. She has decided to go out and interview, say, 10 teachers at the local school.

4. Devise a Methodology

Because it’s an academic study, Laura needs to prove that she did the research systematically. If she doesn’t have a procedure to follow, her results won’t be valid. So, she has to write a section in her dissertation about how she conducted the research to ensure it is reliable. This might be another 2,500 words and explain her methodology (procedure) and how she did it ethically (didn’t cheat or harm anyone).

5. Get Approval to Conduct the Study

Before Laura conducts the study, she’ll have to get it approved by:

• Her supervisor
• Her university’s research ethics committee

Usually, she’ll have to present a written research proposal that outlines her plans and shows she’s thought about her methodology and literature review. This can be a long process, but it’s helped by the fact that he’s already conducted her literature review, written her methodology, and gotten them checked by her supervisor on a regular basis.

6. Conduct the Study

Once she’s gotten approval, Laura will have to go out and conduct the study!

She’ll go out to schools and interview the 10 teachers using a recording device – asking them all the same questions – and then come back to university and look over their answers.

7. Analyze the Results

Laura will have to look through the interviews to see what key points were that kept coming up in her interviews. We call these recurring points ‘key themes’.

The first thing Laura will do is transcribe the interviews. This means she’ll listen to the interviews and type them up word-for-word (‘verbatum’). Then, she’ll print them out and highlight important or revealing quotes that she thinks appeared multiple times in each interview.

Sometimes, people use software to help them find these themes.

8. Write up the Results

Now that Laura thinks she has some key themes from the interviews, she’ll write her ‘analysis’ and /or ‘results’ sections of her dissertation. She will write about all the themes she found and provide some quotes from the teachers to back up her points.

9. Write an Introduction and Conclusion

Lastly, Laura needs to write her introduction and conclusion . These come last when everything else was written. The introduction will give the reader a fly-by of what is said throughout the dissertation. The conclusion will highlight the importance of the results, maybe discuss some weaknesses of her study, and make recommendations for practitioners or future researchers based on her newfound knowledge.

How to Get Started

Dissertation vs. thesis  

While dissertation and thesis are sometimes used interchangeably, they actually refer to two different pieces of writing. A thesis is traditionally completed at the end of a masters program . It is based on pre-existing research and showcases your ability to understand the information you have been learning about in your program.   

A dissertation is much longer than a thesis and is completed at the end of a PhD or doctorate program . It is the last thing you need to complete in order to earn your doctorate in your chosen field. It will be about a topic of your choosing that is within your field of study. Instead of using all pre-existing information though, you will conduct a portion of your own research and propose new ideas.

What do you write about when completing a dissertation?

What you write about will depend on what field of study you are in. A dissertation is designed to be your own. Meaning that what you write about should be a new idea, a new topic, or question that is still unanswered in your field. Something that you will need to collect new data on, potentially interview people for and explore what information is already available.  

Generally, an idea will need to be approved or at least discussed with whoever is overseeing your dissertation before you begin writing. It’s important to put time and effort into choosing a topic that you will be able to find either existing research for and add to, or a topic that you will be able to establish your own methods of data collection for. Again, the goal of your dissertation is to add to your field.   

How long does a dissertation need to be?  

Your dissertation length will vary, but you can generally count on it to be around 2-3 times the length of your thesis. A standard thesis is roughly 80 to 100 pages. So, on the short end you’re looking at a 200 pages dissertation, while the longer end can reach as high as 400 pages.  

How long does it take to write?  

The page count for a dissertation is enough to scare even the best writers away, but take a breath and rest easy knowing that this is not something you complete in just one semester or even two. On the short end you will have a year to write your dissertation, while the longer end can offer as much as two years to complete your dissertation. During this time, you will work with an advisor who can watch over you and help you along the way.  

The parts of a dissertation   

A dissertation is not just one long paper you must write. Thankfully, it is broken down into manageable pieces that you complete over time.  

Choosing a topic  

The first thing you will do is come up with your topic. Again, your topic will need to be approved by whoever is overseeing your dissertation. If they think that it may not be a strong topic, they will let you know. Even if a topic is approved though, you’ll need to do research around that topic first to make sure that it has not already been covered, or if it has that you take into consideration what has been done and add to the topic in a new way.  

Research  

Research can mean looking at what already exists, as well as conducting your own research to add to a proposed idea of yours. Your research can take many different forms depending on what field you are in. Research can be costly at times, so be sure to check out what funding opportunities are available for doctoral research. There are even post PhD research grants you should be familiar with if you intend to continue researching.  

Chapter break down  

A dissertation generally consists of five chapters. We’ve written them out below with a brief description of each and what they include.   

Introduction – Just as you would expect, this is where you will introduce your topic and what you plan to discuss  

Literature review – This section will address the research you have found that has already been done, or found has not been done, that pertains to your topic  

Methodology – How you go about collecting information for your dissertation, whether it be conducting your own research or delving deep into what has already been done, will be discussed in the methodology section 

Results – Your results will analyze the information you gathered  in regard to your topic 

Discussion – Finally, your discussion section will assess the meaning of your results and it is also where you will add your own ideas, rooted in research, about what those results mean in a broader context in regard to your field 

There will be more parts of your dissertation that are not included in the chapters, but the bulk of your dissertation will be made up by these five chapters. Things like title pages, references, appendices, and table of contents will also be included.  

Defending your dissertation  

Believe it or not, it’s not enough just to write your dissertation–you also have to defend your dissertation. This is another reason why taking a thorough amount of time to choose your topic is so important. You’ll likely need to propose your initial dissertation idea, but that will be much simpler and shorter. Your final defense will be much lengthier and in depth.  

During your defense, you will present your dissertation to a committee. It’s likely that you’ll be at least somewhat familiar with those on the committee; they are not just randomly picked. They will ask you questions about your research, and you will need to respond to each question. A defense generally takes around two hours. The point of a defense is not to have people try to undermine your work, but for you to exemplify your expertise in your field.  

Failing your dissertation  

Nobody wants to think about failing, but unfortunately, you can fail your dissertation. However, let’s talk about a few things before we just leave it at that. First, if you are afraid of failing your dissertation, this is something that you should speak to your advisor about. They can help you determine if there should be legitimate concerns or if you are getting in your own head.  

Second, even if you do fail your dissertation, you are usually allowed to resubmit one time. This of course is not ideal, but it does give you a little room to breathe. Your goal is to do great from the start, but remember this is not an easy task. You’ll likely have plenty of bumps along the way! 

Again, if you have concerns about failing, address them sooner rather than later and seek help. There are bound to be plenty of people and services around you, as well as additional services that you can pay for which will help review your materials and guide you along.

Key Takeaways

• Dissertations are completed as the last step of your PhD or doctorate degree 
• Your dissertation will be related to a topic or question in your field of study that you choose 
• Dissertations take anywhere from one to two years to complete and can be upwards of three hundred pages long 
• Your dissertation is designed to showcase your expertise in your field and your addition of new ideas to the field about a particular question or area

• Dissertation Content

A doctoral dissertation makes an original contribution to knowledge, as defined in a discipline or an interdisciplinary domain and addresses a significant researchable problem. Not all problems are researchable and not all are significant. Problems that can be solved by a mere descriptive exercise are not appropriate for the PhD dissertation. Acceptable problems are those that:

• pose a puzzle to the field at a theoretical, methodological, or policy level;
• make analytical demands for solution, rather than mere cataloging or descriptive demands; and
• can yield to a reasonable research methodology.

The doctoral dissertation advisor, reading committee, and oral exam committee provide further guidance and details with regard to dissertation content and format. General formatting and submission guidelines are published by the University Registrar. The American Psychological Association (APA) publication guidelines normally apply to GSE doctoral dissertations, but is not required if the advisor and relevant committees determine that an alternative, and academically acceptable, protocol is more appropriate.

Published Papers and Multiple Authorship

The inclusion of published papers in a dissertation is the prerogative of the major department.  Where published papers or ready-for-publication papers are included, the following criteria must be met:

1. There must be an introductory chapter that integrates the general theme of the research and the relationship between the chapters.  The introduction may also include a review of the literature relevant to the dissertation topic that does not appear in the chapters.

2. Multiple authorship of a published paper should be addressed by clearly designating, in an introduction, the role that the dissertation author had in the research and production of the published paper.  The student must have a major contribution to the research and writing of papers included in the dissertation.

3. There must be adequate referencing of where individual papers have been published.

4. Written permission must be obtained for all copyrighted materials; letters of permission must be uploaded electronically in PDF form when submitting the dissertation.  Please see the following website for more information on the use of copyrighted materials: http://library.stanford.edu/using/copyright-reminder .

5. The submitted material must be in a form that is legible and reproducible as required by these specifications.  The Office of the University Registrar will approve a dissertation if there are no deviations from the normal specifications that would prevent proper dissemination and utilization of the dissertation.  If the published material does not correspond to these standards, it will be necessary for the student to reformat that portion of the dissertation.

6. Multiple authorship has implications with respect to copyright and public release of the material.  Be sure to discuss copyright clearance and embargo options with your co-authors and your advisor well in advance of preparing your thesis for submission.

Dissertation vs Thesis: The Differences that Matter

Updated: January 24, 2023

Published: April 26, 2020

As a graduate student, you will have many different types of challenging coursework and assignments. However, the biggest project that you’ll work on when earning your master’s or doctoral degree will be your thesis or dissertation . The differences between a dissertation vs thesis are plenty. That’s because each of these pieces of writing happen at different times in one’s educational journey.

Let’s break down what a dissertation and thesis are so that you have a strong handle on what’s expected. For both a thesis and a dissertation, there is an obvious fluency and understanding of the subject one studies.

Let’s take a look at their similarities and differences.

What is a dissertation.

When you enter a doctoral program to earn a PhD, you will learn a lot about how to conduct your own research. At the culmination of your degree program, you’ll produce a dissertation.

A dissertation is a lengthy piece of written work that includes original research or expanded research on a new or existing topic. As the doctoral student, you get to choose what you want to explore and write about within your field of study.

What is a Thesis?

A thesis is also a scholarly piece of writing, but it is for those who are graduating from a master’s program. A thesis allows students to showcase their knowledge and expertise within the subject matter they have been studying.

Main Differences Between a Thesis vs. Dissertation

The biggest difference between a thesis and a dissertation is that a thesis is based on existing research.

On the other hand, a dissertation will more than likely require the doctoral student to conduct their own research and then perform analysis. The other big difference is that a thesis is for master’s students and the dissertation is for PhD students.

Structural Differences Between a Thesis and a Dissertation

Structurally, the two pieces of written analysis have many differences.

• A thesis is at least 100 pages in length
• A dissertation is 2-3x that in length
• A thesis expands upon and analyzes existing research
• A dissertation’s content is mostly attributed to the student as the author

Research Content and Oral Presentation

Once completed, some programs require students to orally present their thesis and dissertation to a panel of faculty members.

Typically, a dissertation oral presentation can take several hours. On the other hand, a thesis only takes about an hour to present and answer questions.

Let’s look at how the two scholarly works are similar and different:

Similarities:

• Each is considered a final project and required to graduate
• Both require immense understanding of the material
• Written skills are key to complete both
• Neither can be plagiarized
• Both are used to defend an argument
• Both require analytical skills
• You will have to draft, rewrite, and edit both pieces of writing
• For both, it is useful to have another person look over before submission
• Both papers are given deadlines

Differences:

• A dissertation is longer than a thesis
• A dissertation requires new research
• A dissertation requires a hypothesis that is then proven
• A thesis chooses a stance on an existing idea and defends it with analysis
• A dissertation has a longer oral presentation component

The Differences in Context: Location Matters

The united states.

In the US, everything that was previously listed is how schools differentiate between a thesis and a dissertation. A thesis is performed by master’s students, and a dissertation is written by PhD candidates.

In Europe, the distinction between a thesis and dissertation becomes a little more cloudy. That’s because PhD programs may require a doctoral thesis to graduate. Then, as a part of a broader post-graduate research project, students may complete a dissertation.

The purpose behind written research.

Each piece of writing is an opportunity for a student to demonstrate his or her ability to think critically, express their opinions in writing, and present their findings in front of their department.

Graduate degrees take a lot of time, energy, and hard work to complete. When it comes to writing such lengthy and informative pieces, there is a lot of time management that is involved. The purpose of both a thesis and a dissertation are written proof that you understand and have mastered the subject matter of your degree.

Degree Types

A doctoral degree, or PhD, is the highest degree that one can earn. In most cases, students follow the following path to achieve this level of education: Earn a bachelor’s degree, then a master’s, and then a PhD. While not every job title requires this deep educational knowledge, the salaries that come along with each level of higher education increase accordingly.

Earning Your Degree

Whether you are currently a prospective student considering earning your higher education degree or a student enrolled in a master’s or doctoral program, you know the benefits of education.

However, for some, earning a traditional degree on-campus doesn’t make sense. This could be because of the financial challenges, familial obligations, accessibility, or any other number of reasons.

For students who are seeking their higher education degrees but need a flexible, affordable, and quality alternative to traditional college, take a look at the programs that the University of the People has to offer.

University of the People is an entirely online, US accredited and tuition-free institution dedicated to higher education. You can earn your Master’s in Business Administration or your Master’s in Education . Not to mention, there are a handful of associate’s and bachelor’s degree programs to choose from as well.

The Bottom Line

Regardless of where and when you earn your master’s or doctoral degree, you will likely have to complete a thesis or dissertation. The main difference between a thesis and dissertation is the level at which you complete them. A thesis is for a master’s degree, and a dissertation is for a doctoral degree.

Don’t be overwhelmed by the prospect of having to research and write so much. Your educational journey has prepared you with the right time management skills and writing skills to make this feat achievable!

• 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 .

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!

How do you go about completing a literature review? What's it like to do PhD research? And what actually happens at an MPhil upgrade? You can find out more in our detailed guide to the PhD journey .

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.

How to Write a Literature Review | Guide, Examples, & Templates

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Prevent plagiarism. Run a free check.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

When you’ve finished writing and revising your literature review, don’t forget to proofread thoroughly before submitting. Not a language expert? Check out Scribbr’s professional proofreading services !

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
