What Is a Dissertation? | Guide, Examples, & Template

A dissertation is a long-form piece of academic writing based on original research conducted by you. It is usually submitted as the final step in order to finish a PhD program.

Your dissertation is probably the longest piece of writing you’ve ever completed. It requires solid research, writing, and analysis skills, and it can be intimidating to know where to begin.

Your department likely has guidelines related to how your dissertation should be structured. When in doubt, consult with your supervisor.

Table of contents

Dissertation committee and prospectus process, how to write and structure a dissertation, acknowledgements or preface, list of figures and tables, list of abbreviations, introduction, literature review, methodology, reference list, proofreading and editing, defending your dissertation, free checklist and lecture slides.

When you’ve finished your coursework, as well as any comprehensive exams or other requirements, you advance to “ABD” (All But Dissertation) status. This means you’ve completed everything except your dissertation.

Prior to starting to write, you must form your committee and write your prospectus or proposal . Your committee comprises your adviser and a few other faculty members. They can be from your own department, or, if your work is more interdisciplinary, from other departments. Your committee will guide you through the dissertation process, and ultimately decide whether you pass your dissertation defense and receive your PhD.

Your prospectus is a formal document presented to your committee, usually orally in a defense, outlining your research aims and objectives and showing why your topic is relevant . After passing your prospectus defense, you’re ready to start your research and writing.

The structure of your dissertation depends on a variety of factors, such as your discipline, topic, and approach. Dissertations in the humanities are often structured more like a long essay , building an overall argument to support a central thesis , with chapters organized around different themes or case studies.

However, hard science and social science dissertations typically include a review of existing works, a methodology section, an analysis of your original research, and a presentation of your results , presented in different chapters.

Dissertation examples

We’ve compiled a list of dissertation examples to help you get started.

• Example dissertation #1: Heat, Wildfire and Energy Demand: An Examination of Residential Buildings and Community Equity (a dissertation by C. A. Antonopoulos about the impact of extreme heat and wildfire on residential buildings and occupant exposure risks).
• Example dissertation #2: Exploring Income Volatility and Financial Health Among Middle-Income Households (a dissertation by M. Addo about income volatility and declining economic security among middle-income households).
• Example dissertation #3: The Use of Mindfulness Meditation to Increase the Efficacy of Mirror Visual Feedback for Reducing Phantom Limb Pain in Amputees (a dissertation by N. S. Mills about the effect of mindfulness-based interventions on the relationship between mirror visual feedback and the pain level in amputees with phantom limb pain).

The very first page of your document contains your dissertation title, your name, department, institution, degree program, and submission date. Sometimes it also includes your student number, your supervisor’s name, and the university’s logo.

Read more about title pages

The acknowledgements section is usually optional and gives space for you to thank everyone who helped you in writing your dissertation. This might include your supervisors, participants in your research, and friends or family who supported you. In some cases, your acknowledgements are part of a preface.

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

The abstract is a short summary of your dissertation, usually about 150 to 300 words long. Though this may seem very short, it’s one of the most important parts of your dissertation, because it introduces your work to your audience.

Your abstract should:

• State your main topic and the aims of your research
• Describe your methods
• Summarize your main results
• State your conclusions

Read more about abstracts

The table of contents lists all of your chapters, along with corresponding subheadings and page numbers. This gives your reader an overview of your structure and helps them easily navigate your document.

Remember to include all main parts of your dissertation in your table of contents, even the appendices. It’s easy to generate a table automatically in Word if you used heading styles. Generally speaking, you only include level 2 and level 3 headings, not every subheading you included in your finished work.

Read more about tables of contents

While not usually mandatory, it’s nice to include a list of figures and tables to help guide your reader if you have used a lot of these in your dissertation. It’s easy to generate one of these in Word using the Insert Caption feature.

Read more about lists of figures and tables

Similarly, if you have used a lot of abbreviations (especially industry-specific ones) in your dissertation, you can include them in an alphabetized list of abbreviations so that the reader can easily look up their meanings.

Read more about lists of abbreviations

In addition to the list of abbreviations, if you find yourself using a lot of highly specialized terms that you worry will not be familiar to your reader, consider including a glossary. Here, alphabetize the terms and include a brief description or definition.

Read more about glossaries

The introduction serves to set up your dissertation’s topic, purpose, and relevance. It tells the reader what to expect in the rest of your dissertation. The introduction should:

• Establish your research topic , giving the background information needed to contextualize your work
• Narrow down the focus and define the scope of your research
• Discuss the state of existing research on the topic, showing your work’s relevance to a broader problem or debate
• Clearly state your research questions and objectives
• Outline the flow of the rest of your work

Everything in the introduction should be clear, engaging, and relevant. By the end, the reader should understand the what, why, and how of your research.

Read more about introductions

A formative part of your research is your literature review . This helps you gain a thorough understanding of the academic work that already exists on your topic.

Literature reviews encompass:

• Finding relevant sources (e.g., books and journal articles)
• Assessing the credibility of your sources
• Critically analyzing and evaluating each source
• Drawing connections between them (e.g., themes, patterns, conflicts, or gaps) to strengthen your overall point

A literature review is not merely a summary of existing sources. Your literature review should have a coherent structure and argument that leads to a clear justification for your own research. It may aim to:

• Address a gap in the literature or build on existing knowledge
• Take a new theoretical or methodological approach to your topic
• Propose a solution to an unresolved problem or advance one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework. Here, you define and analyze the key theories, concepts, and models that frame your research.

Read more about theoretical frameworks

Your methodology chapter describes how you conducted your research, allowing your reader to critically assess its credibility. Your methodology section should accurately report what you did, as well as convince your reader that this was the best way to answer your research question.

A methodology section should generally include:

• The overall research approach ( quantitative vs. qualitative ) and research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment )
• Details of where, when, and with whom the research took place
• Any tools and materials you used (e.g., computer programs, lab equipment)
• Your data analysis methods (e.g., statistical analysis , discourse analysis )
• An evaluation or justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. You can structure this section around sub-questions, hypotheses , or themes, but avoid including any subjective or speculative interpretation here.

Your results section should:

• Concisely state each relevant result together with relevant descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Briefly state how the result relates to the question or whether the hypothesis was supported
• Report all results that are relevant to your research questions , including any that did not meet your expectations.

Additional data (including raw numbers, full questionnaires, or interview transcripts) can be included as an appendix. You can include tables and figures, but only if they help the reader better understand your results. Read more about results sections

Your discussion section is your opportunity to explore the meaning and implications of your results in relation to your research question. Here, interpret your results in detail, discussing whether they met your expectations and how well they fit with the framework that you built in earlier chapters. Refer back to relevant source material to show how your results fit within existing research in your field.

Some guiding questions include:

• What do your results mean?
• Why do your results matter?
• What limitations do the results have?

If any of the results were unexpected, offer explanations for why this might be. It’s a good idea to consider alternative interpretations of your data.

Read more about discussion sections

Your dissertation’s conclusion should concisely answer your main research question, leaving your reader with a clear understanding of your central argument and emphasizing what your research has contributed to the field.

In some disciplines, the conclusion is just a short section preceding the discussion section, but in other contexts, it is the final chapter of your work. Here, you wrap up your dissertation with a final reflection on what you found, with recommendations for future research and concluding remarks.

It’s important to leave the reader with a clear impression of why your research matters. What have you added to what was already known? Why is your research necessary for the future of your field?

Read more about conclusions

It is crucial to include a reference list or list of works cited with the full details of all the sources that you used, in order to avoid plagiarism. Be sure to choose one citation style and follow it consistently throughout your dissertation. Each style has strict and specific formatting requirements.

Common styles include MLA , Chicago , and APA , but which style you use is often set by your department or your field.

Create APA citations Create MLA citations

Your dissertation should contain only essential information that directly contributes to answering your research question. Documents such as interview transcripts or survey questions can be added as appendices, rather than adding them to the main body.

Read more about appendices

Making sure that all of your sections are in the right place is only the first step to a well-written dissertation. Don’t forget to leave plenty of time for editing and proofreading, as grammar mistakes and sloppy spelling errors can really negatively impact your work.

Dissertations can take up to five years to write, so you will definitely want to make sure that everything is perfect before submitting. You may want to consider using a professional dissertation editing service , AI proofreader or grammar checker to make sure your final project is perfect prior to submitting.

After your written dissertation is approved, your committee will schedule a defense. Similarly to defending your prospectus, dissertation defenses are oral presentations of your work. You’ll present your dissertation, and your committee will ask you questions. Many departments allow family members, friends, and other people who are interested to join as well.

After your defense, your committee will meet, and then inform you whether you have passed. Keep in mind that defenses are usually just a formality; most committees will have resolved any serious issues with your work with you far prior to your defense, giving you ample time to fix any problems.

As you write your dissertation, you can use this simple checklist to make sure you’ve included all the essentials.

Your dissertation, the final piece of the puzzle that stands between you and the completion of your doctoral degree . Okay, so that’s not the actual definition of the word “dissertation,” but when you’re writing one, that can feel true at times! Keep reading to learn the academic definition and take a more in depth look at what a dissertation is and how to navigate writing one. So, let’s go!

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 master’s 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 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

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.

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.

The academic proofreading tool has been trained on 1000s of academic texts and by native English editors. Making it the most accurate and reliable proofreading tool for students.

Correct my document today

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.

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.

How To Write A Dissertation Or Thesis

8 straightforward steps to craft an a-grade dissertation.

By: Derek Jansen (MBA) Expert Reviewed By: Dr Eunice Rautenbach | June 2020

Writing a dissertation or thesis is not a simple task. It takes time, energy and a lot of will power to get you across the finish line. It’s not easy – but it doesn’t necessarily need to be a painful process. If you understand the big-picture process of how to write a dissertation or thesis, your research journey will be a lot smoother.  

In this post, I’m going to outline the big-picture process of how to write a high-quality dissertation or thesis, without losing your mind along the way. If you’re just starting your research, this post is perfect for you. Alternatively, if you’ve already submitted your proposal, this article which covers how to structure a dissertation might be more helpful.

How To Write A Dissertation: 8 Steps

• Clearly understand what a dissertation (or thesis) is
• Find a unique and valuable research topic
• Craft a convincing research proposal
• Write up a strong introduction chapter
• Review the existing literature and compile a literature review
• Design a rigorous research strategy and undertake your own research
• Present the findings of your research
• Draw a conclusion and discuss the implications

Step 1: Understand exactly what a dissertation is

This probably sounds like a no-brainer, but all too often, students come to us for help with their research and the underlying issue is that they don’t fully understand what a dissertation (or thesis) actually is.

So, what is a dissertation?

At its simplest, a dissertation or thesis is a formal piece of research , reflecting the standard research process . But what is the standard research process, you ask? The research process involves 4 key steps:

• Ask a very specific, well-articulated question (s) (your research topic)
• See what other researchers have said about it (if they’ve already answered it)
• If they haven’t answered it adequately, undertake your own data collection and analysis in a scientifically rigorous fashion
• Answer your original question(s), based on your analysis findings

In short, the research process is simply about asking and answering questions in a systematic fashion . This probably sounds pretty obvious, but people often think they’ve done “research”, when in fact what they have done is:

• Started with a vague, poorly articulated question
• Not taken the time to see what research has already been done regarding the question
• Collected data and opinions that support their gut and undertaken a flimsy analysis
• Drawn a shaky conclusion, based on that analysis

If you want to see the perfect example of this in action, look out for the next Facebook post where someone claims they’ve done “research”… All too often, people consider reading a few blog posts to constitute research. Its no surprise then that what they end up with is an opinion piece, not research. Okay, okay – I’ll climb off my soapbox now.

The key takeaway here is that a dissertation (or thesis) is a formal piece of research, reflecting the research process. It’s not an opinion piece , nor a place to push your agenda or try to convince someone of your position. Writing a good dissertation involves asking a question and taking a systematic, rigorous approach to answering it.

If you understand this and are comfortable leaving your opinions or preconceived ideas at the door, you’re already off to a good start!

Step 2: Find a unique, valuable research topic

As we saw, the first step of the research process is to ask a specific, well-articulated question. In other words, you need to find a research topic that asks a specific question or set of questions (these are called research questions ). Sounds easy enough, right? All you’ve got to do is identify a question or two and you’ve got a winning research topic. Well, not quite…

A good dissertation or thesis topic has a few important attributes. Specifically, a solid research topic should be:

Let’s take a closer look at these:

Attribute #1: Clear

Your research topic needs to be crystal clear about what you’re planning to research, what you want to know, and within what context. There shouldn’t be any ambiguity or vagueness about what you’ll research.

Here’s an example of a clearly articulated research topic:

An analysis of consumer-based factors influencing organisational trust in British low-cost online equity brokerage firms.

As you can see in the example, its crystal clear what will be analysed (factors impacting organisational trust), amongst who (consumers) and in what context (British low-cost equity brokerage firms, based online).

Need a helping hand?

Attribute #2:   Unique

Your research should be asking a question(s) that hasn’t been asked before, or that hasn’t been asked in a specific context (for example, in a specific country or industry).

For example, sticking organisational trust topic above, it’s quite likely that organisational trust factors in the UK have been investigated before, but the context (online low-cost equity brokerages) could make this research unique. Therefore, the context makes this research original.

One caveat when using context as the basis for originality – you need to have a good reason to suspect that your findings in this context might be different from the existing research – otherwise, there’s no reason to warrant researching it.

Attribute #3: Important

Simply asking a unique or original question is not enough – the question needs to create value. In other words, successfully answering your research questions should provide some value to the field of research or the industry. You can’t research something just to satisfy your curiosity. It needs to make some form of contribution either to research or industry.

For example, researching the factors influencing consumer trust would create value by enabling businesses to tailor their operations and marketing to leverage factors that promote trust. In other words, it would have a clear benefit to industry.

So, how do you go about finding a unique and valuable research topic? We explain that in detail in this video post – How To Find A Research Topic . Yeah, we’ve got you covered 😊

Step 3: Write a convincing research proposal

Once you’ve pinned down a high-quality research topic, the next step is to convince your university to let you research it. No matter how awesome you think your topic is, it still needs to get the rubber stamp before you can move forward with your research. The research proposal is the tool you’ll use for this job.

So, what’s in a research proposal?

The main “job” of a research proposal is to convince your university, advisor or committee that your research topic is worthy of approval. But convince them of what? Well, this varies from university to university, but generally, they want to see that:

• You have a clearly articulated, unique and important topic (this might sound familiar…)
• You’ve done some initial reading of the existing literature relevant to your topic (i.e. a literature review)
• You have a provisional plan in terms of how you will collect data and analyse it (i.e. a methodology)

At the proposal stage, it’s (generally) not expected that you’ve extensively reviewed the existing literature , but you will need to show that you’ve done enough reading to identify a clear gap for original (unique) research. Similarly, they generally don’t expect that you have a rock-solid research methodology mapped out, but you should have an idea of whether you’ll be undertaking qualitative or quantitative analysis , and how you’ll collect your data (we’ll discuss this in more detail later).

Long story short – don’t stress about having every detail of your research meticulously thought out at the proposal stage – this will develop as you progress through your research. However, you do need to show that you’ve “done your homework” and that your research is worthy of approval .

So, how do you go about crafting a high-quality, convincing proposal? We cover that in detail in this video post – How To Write A Top-Class Research Proposal . We’ve also got a video walkthrough of two proposal examples here .

Step 4: Craft a strong introduction chapter

Once your proposal’s been approved, its time to get writing your actual dissertation or thesis! The good news is that if you put the time into crafting a high-quality proposal, you’ve already got a head start on your first three chapters – introduction, literature review and methodology – as you can use your proposal as the basis for these.

Handy sidenote – our free dissertation & thesis template is a great way to speed up your dissertation writing journey.

What’s the introduction chapter all about?

The purpose of the introduction chapter is to set the scene for your research (dare I say, to introduce it…) so that the reader understands what you’ll be researching and why it’s important. In other words, it covers the same ground as the research proposal in that it justifies your research topic.

What goes into the introduction chapter?

This can vary slightly between universities and degrees, but generally, the introduction chapter will include the following:

• A brief background to the study, explaining the overall area of research
• A problem statement , explaining what the problem is with the current state of research (in other words, where the knowledge gap exists)
• Your research questions – in other words, the specific questions your study will seek to answer (based on the knowledge gap)
• The significance of your study – in other words, why it’s important and how its findings will be useful in the world

As you can see, this all about explaining the “what” and the “why” of your research (as opposed to the “how”). So, your introduction chapter is basically the salesman of your study, “selling” your research to the first-time reader and (hopefully) getting them interested to read more.

How do I write the introduction chapter, you ask? We cover that in detail in this post .

Step 5: Undertake an in-depth literature review

As I mentioned earlier, you’ll need to do some initial review of the literature in Steps 2 and 3 to find your research gap and craft a convincing research proposal – but that’s just scratching the surface. Once you reach the literature review stage of your dissertation or thesis, you need to dig a lot deeper into the existing research and write up a comprehensive literature review chapter.

What’s the literature review all about?

There are two main stages in the literature review process:

Literature Review Step 1: Reading up

The first stage is for you to deep dive into the existing literature (journal articles, textbook chapters, industry reports, etc) to gain an in-depth understanding of the current state of research regarding your topic. While you don’t need to read every single article, you do need to ensure that you cover all literature that is related to your core research questions, and create a comprehensive catalogue of that literature , which you’ll use in the next step.

Reading and digesting all the relevant literature is a time consuming and intellectually demanding process. Many students underestimate just how much work goes into this step, so make sure that you allocate a good amount of time for this when planning out your research. Thankfully, there are ways to fast track the process – be sure to check out this article covering how to read journal articles quickly .

Literature Review Step 2: Writing up

Once you’ve worked through the literature and digested it all, you’ll need to write up your literature review chapter. Many students make the mistake of thinking that the literature review chapter is simply a summary of what other researchers have said. While this is partly true, a literature review is much more than just a summary. To pull off a good literature review chapter, you’ll need to achieve at least 3 things:

• You need to synthesise the existing research , not just summarise it. In other words, you need to show how different pieces of theory fit together, what’s agreed on by researchers, what’s not.
• You need to highlight a research gap that your research is going to fill. In other words, you’ve got to outline the problem so that your research topic can provide a solution.
• You need to use the existing research to inform your methodology and approach to your own research design. For example, you might use questions or Likert scales from previous studies in your your own survey design .

As you can see, a good literature review is more than just a summary of the published research. It’s the foundation on which your own research is built, so it deserves a lot of love and attention. Take the time to craft a comprehensive literature review with a suitable structure .

But, how do I actually write the literature review chapter, you ask? We cover that in detail in this video post .

Step 6: Carry out your own research

Once you’ve completed your literature review and have a sound understanding of the existing research, its time to develop your own research (finally!). You’ll design this research specifically so that you can find the answers to your unique research question.

There are two steps here – designing your research strategy and executing on it:

1 – Design your research strategy

The first step is to design your research strategy and craft a methodology chapter . I won’t get into the technicalities of the methodology chapter here, but in simple terms, this chapter is about explaining the “how” of your research. If you recall, the introduction and literature review chapters discussed the “what” and the “why”, so it makes sense that the next point to cover is the “how” –that’s what the methodology chapter is all about.

In this section, you’ll need to make firm decisions about your research design. This includes things like:

• Your research philosophy (e.g. positivism or interpretivism )
• Your overall methodology (e.g. qualitative , quantitative or mixed methods)
• Your data collection strategy (e.g. interviews , focus groups, surveys)
• Your data analysis strategy (e.g. content analysis , correlation analysis, regression)

If these words have got your head spinning, don’t worry! We’ll explain these in plain language in other posts. It’s not essential that you understand the intricacies of research design (yet!). The key takeaway here is that you’ll need to make decisions about how you’ll design your own research, and you’ll need to describe (and justify) your decisions in your methodology chapter.

2 – Execute: Collect and analyse your data

Once you’ve worked out your research design, you’ll put it into action and start collecting your data. This might mean undertaking interviews, hosting an online survey or any other data collection method. Data collection can take quite a bit of time (especially if you host in-person interviews), so be sure to factor sufficient time into your project plan for this. Oftentimes, things don’t go 100% to plan (for example, you don’t get as many survey responses as you hoped for), so bake a little extra time into your budget here.

Once you’ve collected your data, you’ll need to do some data preparation before you can sink your teeth into the analysis. For example:

• If you carry out interviews or focus groups, you’ll need to transcribe your audio data to text (i.e. a Word document).
• If you collect quantitative survey data, you’ll need to clean up your data and get it into the right format for whichever analysis software you use (for example, SPSS, R or STATA).

Once you’ve completed your data prep, you’ll undertake your analysis, using the techniques that you described in your methodology. Depending on what you find in your analysis, you might also do some additional forms of analysis that you hadn’t planned for. For example, you might see something in the data that raises new questions or that requires clarification with further analysis.

The type(s) of analysis that you’ll use depend entirely on the nature of your research and your research questions. For example:

• If your research if exploratory in nature, you’ll often use qualitative analysis techniques .
• If your research is confirmatory in nature, you’ll often use quantitative analysis techniques
• If your research involves a mix of both, you might use a mixed methods approach

Again, if these words have got your head spinning, don’t worry! We’ll explain these concepts and techniques in other posts. The key takeaway is simply that there’s no “one size fits all” for research design and methodology – it all depends on your topic, your research questions and your data. So, don’t be surprised if your study colleagues take a completely different approach to yours.

Step 7: Present your findings

Once you’ve completed your analysis, it’s time to present your findings (finally!). In a dissertation or thesis, you’ll typically present your findings in two chapters – the results chapter and the discussion chapter .

What’s the difference between the results chapter and the discussion chapter?

While these two chapters are similar, the results chapter generally just presents the processed data neatly and clearly without interpretation, while the discussion chapter explains the story the data are telling  – in other words, it provides your interpretation of the results.

For example, if you were researching the factors that influence consumer trust, you might have used a quantitative approach to identify the relationship between potential factors (e.g. perceived integrity and competence of the organisation) and consumer trust. In this case:

• Your results chapter would just present the results of the statistical tests. For example, correlation results or differences between groups. In other words, the processed numbers.
• Your discussion chapter would explain what the numbers mean in relation to your research question(s). For example, Factor 1 has a weak relationship with consumer trust, while Factor 2 has a strong relationship.

Depending on the university and degree, these two chapters (results and discussion) are sometimes merged into one , so be sure to check with your institution what their preference is. Regardless of the chapter structure, this section is about presenting the findings of your research in a clear, easy to understand fashion.

Importantly, your discussion here needs to link back to your research questions (which you outlined in the introduction or literature review chapter). In other words, it needs to answer the key questions you asked (or at least attempt to answer them).

For example, if we look at the sample research topic:

In this case, the discussion section would clearly outline which factors seem to have a noteworthy influence on organisational trust. By doing so, they are answering the overarching question and fulfilling the purpose of the research .

For more information about the results chapter , check out this post for qualitative studies and this post for quantitative studies .

Step 8: The Final Step Draw a conclusion and discuss the implications

Last but not least, you’ll need to wrap up your research with the conclusion chapter . In this chapter, you’ll bring your research full circle by highlighting the key findings of your study and explaining what the implications of these findings are.

What exactly are key findings? The key findings are those findings which directly relate to your original research questions and overall research objectives (which you discussed in your introduction chapter). The implications, on the other hand, explain what your findings mean for industry, or for research in your area.

Sticking with the consumer trust topic example, the conclusion might look something like this:

Key findings

This study set out to identify which factors influence consumer-based trust in British low-cost online equity brokerage firms. The results suggest that the following factors have a large impact on consumer trust:

While the following factors have a very limited impact on consumer trust:

Notably, within the 25-30 age groups, Factors E had a noticeably larger impact, which may be explained by…

Implications

The findings having noteworthy implications for British low-cost online equity brokers. Specifically:

The large impact of Factors X and Y implies that brokers need to consider….

The limited impact of Factor E implies that brokers need to…

As you can see, the conclusion chapter is basically explaining the “what” (what your study found) and the “so what?” (what the findings mean for the industry or research). This brings the study full circle and closes off the document.

Let’s recap – how to write a dissertation or thesis

You’re still with me? Impressive! I know that this post was a long one, but hopefully you’ve learnt a thing or two about how to write a dissertation or thesis, and are now better equipped to start your own research.

To recap, the 8 steps to writing a quality dissertation (or thesis) are as follows:

• Understand what a dissertation (or thesis) is – a research project that follows the research process.
• Find a unique (original) and important research topic
• Craft a convincing dissertation or thesis research proposal
• Write a clear, compelling introduction chapter
• Undertake a thorough review of the existing research and write up a literature review
• Undertake your own research
• Present and interpret your findings

Once you’ve wrapped up the core chapters, all that’s typically left is the abstract , reference list and appendices. As always, be sure to check with your university if they have any additional requirements in terms of structure or content.  

Psst... there’s more!

Hello, your write ups is quite educative. However, l have challenges in going about my research questions which is below; *Building the enablers of organisational growth through effective governance and purposeful leadership.*

Very educating.

Just listening to the name of the dissertation makes the student nervous. As writing a top-quality dissertation is a difficult task as it is a lengthy topic, requires a lot of research and understanding and is usually around 10,000 to 15000 words. Sometimes due to studies, unbalanced workload or lack of research and writing skill students look for dissertation submission from professional writers.

Thank you 💕😊 very much. I was confused but your comprehensive explanation has cleared my doubts of ever presenting a good thesis. Thank you.

thank you so much, that was so useful

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.

• Introduction

What are the two types of dissertations?

Skills you need to show, how long is a dissertation, oral examinations (vivas), don’t cheat.

The majority of degrees end with this assignment, but just what is a dissertation?  

Sometimes known as a thesis (in some countries, this term is used only for the final assignments of PhD degrees, while in other countries ‘thesis’ and ‘dissertation’ are interchangeable), a dissertation is a research project completed as part of an undergraduate or postgraduate degree. Typically, a dissertation allows students present their findings in response to a question or proposition that they choose themselves. The aim of the project is to test the independent research skills students have acquired during their time at university, with the assessment used to help determine their final grade. Although there is usually some guidance from your tutors, the dissertation project is largely independent.

For most students this will be the longest, most difficult and most important assignment completed at university, requiring months of preparation and hard work (the library might become a second home). However, it can also be very rewarding, particularly if you’re passionate about your choice of topic. It’s therefore definitely a good idea to make sure you choose a subject you’re genuinely interested in.

The type of dissertation you complete will vary depending on your course of study. One of the main differences is between empirical and non-empirical dissertations.

Empirical dissertation s are dissertations which involve collecting data, for example in a psychology degree. This may mean putting into practice professional and ethical guidelines when collecting data from members of the public. Empirical dissertations in natural and life science subjects may involve or be entirely centered on laboratory work.

Non-empirical dissertations are based on existing data and arguments in the work of others. This is likely to mean spending a lot of time with your head in a book! In this type of dissertation, you need to make sure you don’t just describe what others are saying, but critically analyze the work and explore its practical applications.

No matter what type of dissertation you write, and what topic you choose, you’ll need to demonstrate the following skills:

• Defining and outlining a research area with a clear question
• Identifying the leading issues
• Sourcing the relevant information
• Assessing its reliability and legitimacy
• Evaluating the evidence on all sides of a debate
• Coming to a well-argued conclusion
• Organizing and presenting the outcomes of your work critically, convincingly, and articulately, following all the guidelines on how to format your essay

The length of a dissertation varies between study level and country, but is generally around 10,000-12,000 words at undergraduate level, 15,000-25,000 words at master’s level and up to 50,000 words or more at PhD level.

Testimonials

"I’d been working as a data analyst back in India. I knew what my career prospects were and it was just a case of deciding which university would be better suited. Obviously, that's where the QS rankings proved useful."

Read my story

Saurabh Kulkarni Durham University Business School student

"I chose to remain in India for my gap year to take on several different opportunities and roles and gain more real-life experience. I found out what it’s like to work in an office, and also learned a lot about myself during that time."

Jugnu Nagar JECRC University student

"QS were a huge help from the very beginning. When I felt overwhelmed about the options available, it was my counsellor who helped me to clarify my goals and find a programme that would be best suited for my future."

Bibil Jose Arizona State University student

"I’m grateful to have selected a co-op programme for my degree. It helped me gain significant industry skills and amazing memories that I will take into my career. My resume already looks full of experience before I’ve even graduated."

Pratibha Muthukumarasamy University of Waterloo student

For some advanced degrees (particularly PhDs) you may need to attend an oral examination, which is known as a viva in some countries (short for viva voce, which is Latin for ‘live voice’). The viva will usually start with you giving a short presentation of your work to two or three professors, which is then followed by a questioning/answering period which could last up to two hours.  

Finally, it pretty much goes without saying, but it’s definitely not advisable to pay someone to write your dissertation for you or otherwise cheat in any way. It’s not worth the risk, and the dissertation is meant to be your chance to let your skills shine through. However, asking a supervisor, friend or family member to take a look at your dissertation is fine. Your supervisor is on hand to guide you, so don’t worry if you need to ask for help.

What is a dissertation? How is it different from an essay?

• Getting it down on paper
• Drafting and rewriting
• Planning your dissertation
• Planning for length
• Planning for content
• Abstracts, tone, unity of style
• General comments

There are some obvious differences: an essay is relatively short – usually 1500 to 2500 words – and you are told clearly what to do by someone else. For example: Describe and evaluate major theories of globalisation.

A dissertation is a subject you chose for yourself. The first usage of the word in the English language in 1651 also gives a useful starting definition: “an extended written treatment of a subject”.

Another useful clue is found in the Latin origin of the word – dissertation comes from a Latin word ‘dissertare’ = ‘to debate’.

What does the word ‘debate’ imply? A discussion involving different points of view or sets of ideas. A dissertation will therefore not only examine a subject but will review different points of view about that subject.

Here’s another definition that underlines some more important characteristics of a dissertation: “a substantial paper that is typically based on original research and that gives evidence of the candidate’s mastery both of her own subject and of scholarly method.”

A dissertation will show that the writer knows her subject, the key facts and different points of view in it – but it also advances a point of view resulting from original research. Remember that ‘original’ does not mean ‘something that’s never been done before’ but rather ‘something that you do for yourself’.

A dissertation also “gives evidence of the candidate’s mastery […] of scholarly method”. This sounds terribly daunting but don’t be put off. The phrase is telling you that you will have to lift your game to write a successful dissertation. ‘Scholarly method’ means that you will be expected to do more and better reading and research than for a standard undergraduate essay. It means that your work will display accuracy and skill in its investigation and discussion of a subject. It means that your discussion will give evidence of critical analysis i.e. standing back from your subject and weighing up pros and cons. It means you will show that you understand that, for example, aspects of particular theories or viewpoints are open to question.

Look up a word, learn it forever.

Dissertation.

Other forms: dissertations

A dissertation is a long piece of writing that uses research to bring to light an original idea. Don't go to grad school unless you're prepared to write, say, a 300-page dissertation on some topic.

In everyday speech, we sometimes accuse people of delivering dissertations when they overload us with dull information. If you're annoyed with a long memo from your office manager about keeping the kitchen clean, you could mutter to a coworker, “How’d you like that dissertation Felix posted about rinsing out our mugs?”

Definition of thesis

Did you know.

In high school, college, or graduate school, students often have to write a thesis on a topic in their major field of study. In many fields, a final thesis is the biggest challenge involved in getting a master's degree, and the same is true for students studying for a Ph.D. (a Ph.D. thesis is often called a dissertation ). But a thesis may also be an idea; so in the course of the paper the student may put forth several theses (notice the plural form) and attempt to prove them.
