Dissertation Explained: A Grad Student’s Guide

Updated: June 19, 2024

Published: March 10, 2020

Higher education is filled with milestones. When completing your PhD , you will be required to complete a dissertation. Even if you’ve heard this word thrown around before, you still may be questioning “What is a dissertation?” It’s a common question, especially for those considering to join or are already in a graduate program. As such, here’s everything you need to know about dissertations.

What is a Dissertation?

A dissertation is a written document that details research. A dissertation also signifies the completion of your PhD program. It is required to earn a PhD degree, which stands for Doctor of Philosophy.

A PhD is created from knowledge acquired from:

1. Coursework:

A PhD program consists of academic courses that are usually small in size and challenging in content. Most PhD courses consist of a high amount and level of reading and writing per week. These courses will help prepare you for your dissertation as they will teach research methodology.

2. Research:

For your dissertation, it is likely that you will have the choice between performing your own research on a subject , or expanding on existing research. Likely, you will complete a mixture of the two. For those in the hard sciences, you will perform research in a lab. For those in humanities and social sciences, research may mean gathering data from surveys or existing research.

3. Analysis:

Once you have collected the data you need to prove your point, you will have to analyze and interpret the information. PhD programs will prepare you for how to conduct analysis, as well as for how to position your research into the existing body of work on the subject matter.

4. Support:

The process of writing and completing a dissertation is bigger than the work itself. It can lead to research positions within the university or outside companies. It may mean that you will teach and share your findings with current undergraduates, or even be published in academic journals. How far you plan to take your dissertation is your choice to make and will require the relevant effort to accomplish your goals.

Moving from Student to Scholar

In essence, a dissertation is what moves a doctoral student into becoming a scholar. Their research may be published, shared, and used as educational material moving forwards.

Thesis vs. Dissertation

Basic differences.

Grad students may conflate the differences between a thesis and a dissertation.

Simply put, a thesis is what you write to complete a master’s degree. It summarizes existing research and signifies that you understand the subject matter deeply.

On the other hand, a dissertation is the culmination of a doctoral program. It will likely require your own research and it can contribute an entirely new idea into your field.

Structural Differences

When it comes to the structure, a thesis and dissertation are also different. A thesis is like the research papers you complete during undergraduate studies. A thesis displays your ability to think critically and analyze information. It’s less based on research that you’ve completed yourself and more about interpreting and analyzing existing material. They are generally around 100 pages in length.

A dissertation is generally two to three times longer compared to a thesis. This is because the bulk of the information is garnered from research you’ve performed yourself. Also, if you are providing something new in your field, it means that existing information is lacking. That’s why you’ll have to provide a lot of data and research to back up your claims.

Your Guide: Structuring a Dissertation

Dissertation length.

The length of a dissertation varies between study level and country. At an undergraduate level, this is more likely referred to as a research paper, which is 10,000 to 12,000 words on average. At a master’s level, the word count may be 15,000 to 25,000, and it will likely be in the form of a thesis. For those completing their PhD, then the dissertation could be 50,000 words or more.

Format of the dissertation.

Here are the items you must include in a dissertation. While the format may slightly vary, here’s a look at one way to format your dissertation:

1. Title page:

This is the first page which includes: title, your name, department, degree program, institution, and submission date. Your program may specify exactly how and what they want you to include on the title page.

2. Acknowledgements:

This is optional, but it is where you can express your gratitude to those who have helped you complete your dissertation (professors, research partners, etc.).

3. Abstract:

The abstract is about 150-300 words and summarizes what your research is about. You state the main topic, the methods used, the main results, and your conclusion.

4. Table of Contents

Here, you list the chapter titles and pages to serve as a wayfinding tool for your readers.

5. List of Figures and Tables:

This is like the table of contents, but for graphs and figures.

6. List of Abbreviations:

If you’ve constantly abbreviated words in your content, define them in a list at the beginning.

7. Glossary:

In highly specialized work, it’s likely that you’ve used words that most people may not understand, so a glossary is where you define these terms.

8. Introduction:

Your introduction sets up the topic, purpose, and relevance. It’s where readers will understand what they expect to gain from your dissertation.

9. Literature Review / Theoretical Framework:

Based on the research you performed to create your own dissertation, you’ll want to summarize and address the gaps in what you researched.

10. Methodology

This is where you define how you conducted your research. It offers credibility for you as a source of information. You should give all the details as to how you’ve conducted your research, including: where and when research took place, how it was conducted, any obstacles you faced, and how you justified your findings.

11. Results:

This is where you share the results that have helped contribute to your findings.

12. Discussion:

In the discussion section, you explain what these findings mean to your research question. Were they in line with your expectations or did something jump out as surprising? You may also want to recommend ways to move forward in researching and addressing the subject matter.

13. Conclusion:

A conclusion ties it all together and summarizes the answer to the research question and leaves your reader clearly understanding your main argument.

14. Reference List:

This is the equivalent to a works cited or bibliography page, which documents all the sources you used to create your dissertation.

15. Appendices:

If you have any information that was ancillary to creating the dissertation, but doesn’t directly fit into its chapters, then you can add it in the appendix.

Drafting and Rewriting

As with any paper, especially one of this size and importance, the writing requires a process. It may begin with outlines and drafts, and even a few rewrites. It’s important to proofread your dissertation for both grammatical mistakes, but also to ensure it can be clearly understood.

It’s always useful to read your writing out loud to catch mistakes. Also, if you have people who you trust to read it over — like a peer, family member, mentor, or professor — it’s very helpful to get a second eye on your work.

How is it Different from an Essay?

There are a few main differences between a dissertation and an essay. For starters, an essay is relatively short in comparison to a dissertation, which includes your own body of research and work. Not only is an essay shorter, but you are also likely given the topic matter of an essay. When it comes to a dissertation, you have the freedom to construct your own argument, conduct your own research, and then prove your findings.

Types of Dissertations

You can choose what type of dissertation you complete. Often, this depends on the subject and doctoral degree, but the two main types are:

This relies on conducting your own research.

Non-empirical:

This relies on studying existing research to support your argument.

More things you should know.

A dissertation is certainly no easy feat. Here’s a few more things to remember before you get started writing your own:

1. Independent by Nature:

The process of completing a dissertation is self-directed, and therefore can feel overwhelming. However, if you approach it like the new experience that it is with an open-mind and willingness to learn, you will make it through!

2. Seek Support:

There are countless people around to offer support. From professors to peers, you can always ask for help throughout the process.

3. Writing Skills:

The process of writing a dissertation will further hone your writing skills which will follow you throughout your life. These skills are highly transferable on the job, from having the ability to communicate to also developing analytical and critical thinking skills.

4. Time Management:

You can work backwards from the culmination of your program to break down this gargantuan task into smaller pieces. That way, you can manage your time to chip away at the task throughout the length of the program.

5. Topic Flexibility:

It’s okay to change subject matters and rethink the point of your dissertation. Just try as much as possible to do this early in the process so you don’t waste too much time and energy.

The Wrap Up

A dissertation marks the completion of your doctoral program and moves you from being a student to being a scholar. While the process is long and requires a lot of effort and energy, you have the power to lend an entirely new research and findings into your field of expertise.

As always, when in the thick of things, remember why you started. Completing both your dissertation and PhD is a commendable accomplishment.

How to Write a Dissertation | A Guide to Structure & Content

A dissertation or thesis is a long piece of academic writing based on original research, submitted as part of an undergraduate or postgraduate degree.

The structure of a dissertation depends on your field, but it is usually divided into at least four or five chapters (including an introduction and conclusion chapter).

The most common dissertation structure in the sciences and social sciences includes:

• An introduction to your topic
• A literature review that surveys relevant sources
• An explanation of your methodology
• An overview of the results of your research
• A discussion of the results and their implications
• A conclusion that shows what your research has contributed

Dissertations in the humanities are often structured more like a long essay , building an argument by analysing primary and secondary sources . Instead of the standard structure outlined here, you might organise your chapters around different themes or case studies.

Other important elements of the dissertation include the title page , abstract , and reference list . If in doubt about how your dissertation should be structured, always check your department’s guidelines and consult with your supervisor.

Table of contents

Acknowledgements, table of contents, list of figures and tables, list of abbreviations, introduction, literature review / theoretical framework, methodology, reference list.

The very first page of your document contains your dissertation’s 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. Many programs have strict requirements for formatting the dissertation title page .

The title page is often used as cover when printing and binding your dissertation .

Prevent plagiarism, run a free check.

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.

The abstract is a short summary of your dissertation, usually about 150-300 words long. You should write it at the very end, when you’ve completed the rest of the dissertation. In the abstract, make sure to:

• State the main topic and aims of your research
• Describe the methods you used
• Summarise the main results
• State your conclusions

Although the abstract is very short, it’s the first part (and sometimes the only part) of your dissertation that people will read, so it’s important that you get it right. If you’re struggling to write a strong abstract, read our guide on how to write an abstract .

In the table of contents, list all of your chapters and subheadings and their page numbers. The dissertation contents page gives the reader an overview of your structure and helps easily navigate the document.

All parts of your dissertation should be included in the table of contents, including the appendices. You can generate a table of contents automatically in Word.

If you have used a lot of tables and figures in your dissertation, you should itemise them in a numbered list . You can automatically generate this list using the Insert Caption feature in Word.

If you have used a lot of abbreviations in your dissertation, you can include them in an alphabetised list of abbreviations so that the reader can easily look up their meanings.

If you have used a lot of highly specialised terms that will not be familiar to your reader, it might be a good idea to include a glossary . List the terms alphabetically and explain each term with a brief description or definition.

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

• Establish your research topic , giving necessary background information to contextualise your work
• Narrow down the focus and define the scope of the research
• Discuss the state of existing research on the topic, showing your work’s relevance to a broader problem or debate
• Clearly state your objectives and research questions , and indicate how you will answer them
• Give an overview of your dissertation’s structure

Everything in the introduction should be clear, engaging, and relevant to your research. By the end, the reader should understand the what , why and how of your research. Not sure how? Read our guide on how to write a dissertation introduction .

Before you start on your research, you should have conducted a literature review to gain a thorough understanding of the academic work that already exists on your topic. This means:

• Collecting sources (e.g. books and journal articles) and selecting the most relevant ones
• Critically evaluating and analysing each source
• Drawing connections between them (e.g. themes, patterns, conflicts, gaps) to make an overall point

In the dissertation literature review chapter or section, you shouldn’t just summarise existing studies, but develop a coherent structure and argument that leads to a clear basis or justification for your own research. For example, it might aim to show how your research:

• Addresses a gap in the literature
• Takes a new theoretical or methodological approach to the topic
• Proposes a solution to an unresolved problem
• Advances a theoretical debate
• Builds on and strengthens existing knowledge with new data

The literature review often becomes the basis for a theoretical framework , in which you define and analyse the key theories, concepts and models that frame your research. In this section you can answer descriptive research questions about the relationship between concepts or variables.

The methodology chapter or section describes how you conducted your research, allowing your reader to assess its validity. You should generally include:

• The overall approach and type of research (e.g. qualitative, quantitative, experimental, ethnographic)
• Your methods of collecting data (e.g. interviews, surveys, archives)
• Details of where, when, and with whom the research took place
• Your methods of analysing data (e.g. statistical analysis, discourse analysis)
• Tools and materials you used (e.g. computer programs, lab equipment)
• A discussion of any obstacles you faced in conducting the research and how you overcame them
• An evaluation or justification of your methods

Your aim in the methodology is to accurately report what you did, as well as convincing the reader that this was the best approach to answering your research questions or objectives.

Next, you report the results of your research . You can structure this section around sub-questions, hypotheses, or topics. Only report results that are relevant to your objectives and research questions. In some disciplines, the results section is strictly separated from the discussion, while in others the two are combined.

For example, for qualitative methods like in-depth interviews, the presentation of the data will often be woven together with discussion and analysis, while in quantitative and experimental research, the results should be presented separately before you discuss their meaning. If you’re unsure, consult with your supervisor and look at sample dissertations to find out the best structure for your research.

In the results section it can often be helpful to include tables, graphs and charts. Think carefully about how best to present your data, and don’t include tables or figures that just repeat what you have written  –  they should provide extra information or usefully visualise the results in a way that adds value to your text.

Full versions of your data (such as interview transcripts) can be included as an appendix .

The discussion  is where you explore the meaning and implications of your results in relation to your research questions. Here you should interpret the results in detail, discussing whether they met your expectations and how well they fit with the framework that you built in earlier chapters. 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 and discuss any limitations that might have influenced the results.

The discussion should reference other scholarly work to show how your results fit with existing knowledge. You can also make recommendations for future research or practical action.

The dissertation conclusion should concisely answer the main research question, leaving the reader with a clear understanding of your central argument. Wrap up your dissertation with a final reflection on what you did and how you did it. The conclusion often also includes recommendations for research or practice.

In this section, it’s important to show how your findings contribute to knowledge in the field and why your research matters. What have you added to what was already known?

You must include full details of all sources that you have cited in a reference list (sometimes also called a works cited list or bibliography). It’s important to follow a consistent reference style . Each style has strict and specific requirements for how to format your sources in the reference list.

The most common styles used in UK universities are Harvard referencing and Vancouver referencing . Your department will often specify which referencing style you should use – for example, psychology students tend to use APA style , humanities students often use MHRA , and law students always use OSCOLA . M ake sure to check the requirements, and ask your supervisor if you’re unsure.

To save time creating the reference list and make sure your citations are correctly and consistently formatted, you can use our free APA Citation Generator .

Your dissertation itself should contain only essential information that directly contributes to answering your research question. Documents you have used that do not fit into the main body of your dissertation (such as interview transcripts, survey questions or tables with full figures) can be added as appendices .

How to Write a Dissertation: Step-by-Step Guide

• Doctoral students write and defend dissertations to earn their degrees.
• Most dissertations range from 100-300 pages, depending on the field.
• Taking a step-by-step approach can help students write their dissertations.

Whether you’re considering a doctoral program or you recently passed your comprehensive exams, you’ve probably wondered how to write a dissertation. Researching, writing, and defending a dissertation represents a major step in earning a doctorate.

But what is a dissertation exactly? A dissertation is an original work of scholarship that contributes to the field. Doctoral candidates often spend 1-3 years working on their dissertations. And many dissertations top 200 or more pages.

Starting the process on the right foot can help you complete a successful dissertation. Breaking down the process into steps may also make it easier to finish your dissertation.

How to Write a Dissertation in 12 Steps

A dissertation demonstrates mastery in a subject. But how do you write a dissertation? Here are 12 steps to successfully complete a dissertation.

Choose a Topic

It sounds like an easy step, but choosing a topic will play an enormous role in the success of your dissertation. In some fields, your dissertation advisor will recommend a topic. In other fields, you’ll develop a topic on your own.

Read recent work in your field to identify areas for additional scholarship. Look for holes in the literature or questions that remain unanswered.

After coming up with a few areas for research or questions, carefully consider what’s feasible with your resources. Talk to your faculty advisor about your ideas and incorporate their feedback.

Conduct Preliminary Research

Before starting a dissertation, you’ll need to conduct research. Depending on your field, that might mean visiting archives, reviewing scholarly literature , or running lab tests.

Use your preliminary research to hone your question and topic. Take lots of notes, particularly on areas where you can expand your research.

Read Secondary Literature

A dissertation demonstrates your mastery of the field. That means you’ll need to read a large amount of scholarship on your topic. Dissertations typically include a literature review section or chapter.

Create a list of books, articles, and other scholarly works early in the process, and continue to add to your list. Refer to the works cited to identify key literature. And take detailed notes to make the writing process easier.

Write a Research Proposal

In most doctoral programs, you’ll need to write and defend a research proposal before starting your dissertation.

The length and format of your proposal depend on your field. In many fields, the proposal will run 10-20 pages and include a detailed discussion of the research topic, methodology, and secondary literature.

Your faculty advisor will provide valuable feedback on turning your proposal into a dissertation.

Research, Research, Research

Doctoral dissertations make an original contribution to the field, and your research will be the basis of that contribution.

The form your research takes will depend on your academic discipline. In computer science, you might analyze a complex dataset to understand machine learning. In English, you might read the unpublished papers of a poet or author. In psychology, you might design a study to test stress responses. And in education, you might create surveys to measure student experiences.

Work closely with your faculty advisor as you conduct research. Your advisor can often point you toward useful resources or recommend areas for further exploration.

Look for Dissertation Examples

Writing a dissertation can feel overwhelming. Most graduate students have written seminar papers or a master’s thesis. But a dissertation is essentially like writing a book.

Looking at examples of dissertations can help you set realistic expectations and understand what your discipline wants in a successful dissertation. Ask your advisor if the department has recent dissertation examples. Or use a resource like ProQuest Dissertations to find examples.

Doctoral candidates read a lot of monographs and articles, but they often do not read dissertations. Reading polished scholarly work, particularly critical scholarship in your field, can give you an unrealistic standard for writing a dissertation.

Write Your Body Chapters

By the time you sit down to write your dissertation, you’ve already accomplished a great deal. You’ve chosen a topic, defended your proposal, and conducted research. Now it’s time to organize your work into chapters.

As with research, the format of your dissertation depends on your field. Your department will likely provide dissertation guidelines to structure your work. In many disciplines, dissertations include chapters on the literature review, methodology, and results. In other disciplines, each chapter functions like an article that builds to your overall argument.

Start with the chapter you feel most confident in writing. Expand on the literature review in your proposal to provide an overview of the field. Describe your research process and analyze the results.

Meet With Your Advisor

Throughout the dissertation process, you should meet regularly with your advisor. As you write chapters, send them to your advisor for feedback. Your advisor can help identify issues and suggest ways to strengthen your dissertation.

Staying in close communication with your advisor will also boost your confidence for your dissertation defense. Consider sharing material with other members of your committee as well.

Write Your Introduction and Conclusion

It seems counterintuitive, but it’s a good idea to write your introduction and conclusion last . Your introduction should describe the scope of your project and your intervention in the field.

Many doctoral candidates find it useful to return to their dissertation proposal to write the introduction. If your project evolved significantly, you will need to reframe the introduction. Make sure you provide background information to set the scene for your dissertation. And preview your methodology, research aims, and results.

The conclusion is often the shortest section. In your conclusion, sum up what you’ve demonstrated, and explain how your dissertation contributes to the field.

Edit Your Draft

You’ve completed a draft of your dissertation. Now, it’s time to edit that draft.

For some doctoral candidates, the editing process can feel more challenging than researching or writing the dissertation. Most dissertations run a minimum of 100-200 pages , with some hitting 300 pages or more.

When editing your dissertation, break it down chapter by chapter. Go beyond grammar and spelling to make sure you communicate clearly and efficiently. Identify repetitive areas and shore up weaknesses in your argument.

Incorporate Feedback

Writing a dissertation can feel very isolating. You’re focused on one topic for months or years, and you’re often working alone. But feedback will strengthen your dissertation.

You will receive feedback as you write your dissertation, both from your advisor and other committee members. In many departments, doctoral candidates also participate in peer review groups to provide feedback.

Outside readers will note confusing sections and recommend changes. Make sure you incorporate the feedback throughout the writing and editing process.

Defend Your Dissertation

Congratulations — you made it to the dissertation defense! Typically, your advisor will not let you schedule the defense unless they believe you will pass. So consider the defense a culmination of your dissertation process rather than a high-stakes examination.

The format of your defense depends on the department. In some fields, you’ll present your research. In other fields, the defense will consist of an in-depth discussion with your committee.

Walk into your defense with confidence. You’re now an expert in your topic. Answer questions concisely and address any weaknesses in your study. Once you pass the defense, you’ll earn your doctorate.

Writing a dissertation isn’t easy — only around 55,000 students earned a Ph.D. in 2020, according to the National Center for Science and Engineering Statistics. However, it is possible to successfully complete a dissertation by breaking down the process into smaller steps.

Frequently Asked Questions About Dissertations

What is a dissertation.

A dissertation is a substantial research project that contributes to your field of study. Graduate students write a dissertation to earn their doctorate.

The format and content of a dissertation vary widely depending on the academic discipline. Doctoral candidates work closely with their faculty advisor to complete and defend the dissertation, a process that typically takes 1-3 years.

How long is a dissertation?

The length of a dissertation varies by field. Harvard’s graduate school says most dissertations fall between 100-300 pages .

Doctoral candidate Marcus Beck analyzed the length of University of Minnesota dissertations by discipline and found that history produces the longest dissertations, with an average of nearly 300 pages, while mathematics produces the shortest dissertations at just under 100 pages.

What’s the difference between a dissertation vs. a thesis?

Dissertations and theses demonstrate academic mastery at different levels. In U.S. graduate education, master’s students typically write theses, while doctoral students write dissertations. The terms are reversed in the British system.

In the U.S., a dissertation is longer, more in-depth, and based on more research than a thesis. Doctoral candidates write a dissertation as the culminating research project of their degree. Undergraduates and master’s students may write shorter theses as part of their programs.

The 8 Most Asked Questions About Dissertations

A Ph.D. represents the highest level of education in most fields. People who earn this degree earn the honorific of “doctor” and are considered experts in their field. A doctoral degree is often a prerequisite for teaching at the highest levels in academia or ascending career ladders in education, the government and the nonprofit space.

In 2020 , doctoral degree holders had median weekly earnings of $1,885 and an unemployment rate of 2.5%—lower than any other group. And yet, the dissertation is often a major barrier to completing a doctorate and realizing its many financial and personal benefits. 

So what is a dissertation, and what role does it play in your educational trajectory? At SNU, we value exceptional dissertations and integrate the writing process into your coursework. Here are the most common questions we hear about writing dissertations and earning your doctorate.

1. What is a dissertation?

A dissertation is a published piece of academic research. Through your dissertation research , you become an expert in a specific academic niche. After writing your dissertation, you then defend it to a committee of experts in the field. A dissertation is integral to the process of earning a doctoral degree, contributing innovative ideas to your chosen field. Until you have written, published and defended a dissertation, you can’t graduate from a doctoral-level program.

2. Why are dissertations so important?

Dissertations are the crucial piece of research in most doctoral-level programs. The process of writing, researching and amending the dissertation serves several important goals: 

• It contributes novel research to the field, supporting innovation, growth and ongoing scholarship. 
• It requires students to write a substantive piece of academic research across many semesters, sharpening research skills and expertise. 
• It demands that s tudents defend their research, ensuring strong communication and critical thinking skills. 
• It requires deep, comprehensive research—including a literature review—improving reading comprehension and writing skills. 
• It is a challenging project that serves as a test of the skills you might use as an academic professional in your chosen field. 
• It helps establish new members of an academic discipline as contributors to the field. 
• It fosters academic connections as you interview sources and defend your work.

3. Why do so many students struggle with the dissertation?

The dissertation process is difficult. However, this difficulty establishes the credibility of doctoral degrees, proving that the student can commit to long-term, intensive research and become a true subject-matter expert. 

However, for many adult learners, the dissertation proves especially challenging thanks to work-life balance difficulties, financial constraints and lack of family or institutional support. At SNU, we know that a dissertation is critical to your growth as an academic. But we also know that institutional support can make a big difference in your ability to finish this impressive work. That’s why we integrate dissertation writing into our curriculum, rather than leaving you to do it all on your own time. 

One study suggests that more than half of students never complete their dissertation. Other research indicates that academic reforms that help students with their work reduce dropout rates, ensuring more students complete their dissertation and earn the coveted title of doctor.

4. How long is a dissertation?

Most dissertations are 100 pages or longer — roughly the length of a book. The specific length of your dissertation depends on the type of research, how much research exists in the field and similar factors. The goal of dissertation writing is not to attain a specific length, but to be comprehensive and thoughtful. It anticipates and answers potential objections, gives appropriate credit to the source materials and reviews prior work in the field. 

Your dissertation review committee is more interested in a comprehensive dissertation that displays your critical thinking and research skills than they are in a dissertation of a specific length. Excessive wordiness without value wastes a reader’s time.  

The right length for a dissertation depends on several factors: 

• How much research already exists in the field?
• What field are you publishing in?
• What type of research are you doing?
• Is your research controversial?
• How much space do you need to explain your research and address objections?

Put simply: A dissertation should be long enough to comprehensively cover the subject, but no longer.

5. How do you write a dissertation?

In general, the dissertation process follows this schedule: 

• Research the field and identify potential topics. 
• Meet with an advisor to choose and improve a topic. 
• Perform a literature review. 
• Conduct new research. 
• Write the dissertation. 
• Edit the dissertation. 
• Defend the dissertation.

Each step involves weeks to months of work and many phases of revision, reevaluation and research. At SNU, we incorporate many phases of the writing and research process into your coursework. This ensures you are on track to graduate and addresses dissertation writing challenges before they snowball into a serious problem.

6. When should you start writing a dissertation?

The dissertation writing process should begin almost as soon as you enroll in school. That doesn’t necessarily mean you need to have content written on your first day of class. Instead, you will need to engage in substantive pre-writing that includes: 

• Familiarizing yourself with relevant research in the field. 
• Developing an opinion on recent research. 
• Designing your research to address a clear and narrowly defined topic. 

As you hone in on your topic, you can begin the writing and research portion of the project. In most cases, this starts within a semester or two of enrollment. A dissertation is not something you can leave until the last semester or shortly before graduation. SNU ensures this doesn’t happen by integrating the writing process into your coursework. You will start working on your dissertation early, preventing you from becoming overwhelmed.

7. How do you cite a dissertation?

A dissertation is a published scholarly work. Each style manual has specific instructions for citing a dissertation, so be sure to consult the style manual you’re using. 

You can cite other dissertations in your dissertation. In many cases, dissertations can provide useful starting points for your research. The literature reviews they contain may also help with your literature review.

8. How do you choose a school for your dissertation?

Choosing the right school for your dissertation can mean the difference between finishing this scholarly work and languishing at the dreaded “ all-but-dissertation” (ABD) stage . SNU specializes in supporting adult learners by encouraging intensive research and protecting your work-life balance. 

At SNU, your dissertation is a part of your coursework . You will get support from start to finish, including a dissertation advisor who is an expert in your chosen field. We are here for you, and we want to see you succeed.

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.

Thank you so much GradCoach,

This is like a light at the end of the tunnel. You are a lifesaver. Thank you once again.

hello, I’m so grateful for such great information. It appears basic, but it is so relevant in understanding the research process.

Your website is very helpful for writing thesis. A big well done to the team. Do you have a website for paper writing and academic publishing or how to publish my thesis, how to land a fully funded PhD, etc. Just the general upward trajectory in the academia. Thank you

I have learned a lot from the lectures, it was beneficial and helped me a lot in my research journey. Thank you very much

Thank you for your gifts of enlightenment to a person like me who’s always a student. May your ‘well’not dry out.

It’s quite a fun and superb, now I have come to believe that the way one teach can have an impact in understanding and can change one’s assumption and position about a subject or a problem, before I came here and learn I consider research methodology a hard thing because, I wasn’t taught by a mentor like this one. Thanks so much who ever have make this effort to make this something easy and engaging

I can’t imagine that world has achieved major aspects of every field of study

Thank you very much for all the valuable, wonderful and comprehensive amount of information… I highly appreciate your support, 100% I recommend you

This topic is intended for my MPhil. Work (The perception of parents on Technical and Vocational Education, the impact on educational policy). May you consider the suitability of the topic for me and refine if the need be. Thank you,

Hello here…

i have gone through the notes and it is interesting. All i need now is a pdf file that contain a whole dissertation writing inclusive of chapter 1 to 5 on motivation as a topic… thanks

Remarkable!!! You made it sound so simple

I got stuck in my writing because I need to change my topic. I am getting scared as I have a semester left 🙁

Thanks for such an educational opportunity and support

Thanks for your educational opportunity and support
