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

  • 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.

what is a dissertation?

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.

"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.

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.

Correct my document today

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 .

Dissertation Structure & Layout 101: How to structure your dissertation, thesis or research project.

By: Derek Jansen (MBA) Reviewed By: David Phair (PhD) | July 2019

So, you’ve got a decent understanding of what a dissertation is , you’ve chosen your topic and hopefully you’ve received approval for your research proposal . Awesome! Now its time to start the actual dissertation or thesis writing journey.

To craft a high-quality document, the very first thing you need to understand is dissertation structure . In this post, we’ll walk you through the generic dissertation structure and layout, step by step. We’ll start with the big picture, and then zoom into each chapter to briefly discuss the core contents. If you’re just starting out on your research journey, you should start with this post, which covers the big-picture process of how to write a dissertation or thesis .

Dissertation structure and layout - the basics

*The Caveat *

In this post, we’ll be discussing a traditional dissertation/thesis structure and layout, which is generally used for social science research across universities, whether in the US, UK, Europe or Australia. However, some universities may have small variations on this structure (extra chapters, merged chapters, slightly different ordering, etc).

So, always check with your university if they have a prescribed structure or layout that they expect you to work with. If not, it’s safe to assume the structure we’ll discuss here is suitable. And even if they do have a prescribed structure, you’ll still get value from this post as we’ll explain the core contents of each section.  

Overview: S tructuring a dissertation or thesis

  • Acknowledgements page
  • Abstract (or executive summary)
  • Table of contents , list of figures and tables
  • Chapter 1: Introduction
  • Chapter 2: Literature review
  • Chapter 3: Methodology
  • Chapter 4: Results
  • Chapter 5: Discussion
  • Chapter 6: Conclusion
  • Reference list

As I mentioned, some universities will have slight variations on this structure. For example, they want an additional “personal reflection chapter”, or they might prefer the results and discussion chapter to be merged into one. Regardless, the overarching flow will always be the same, as this flow reflects the research process , which we discussed here – i.e.:

  • The introduction chapter presents the core research question and aims .
  • The literature review chapter assesses what the current research says about this question.
  • The methodology, results and discussion chapters go about undertaking new research about this question.
  • The conclusion chapter (attempts to) answer the core research question .

In other words, the dissertation structure and layout reflect the research process of asking a well-defined question(s), investigating, and then answering the question – see below.

A dissertation's structure reflect the research process

To restate that – the structure and layout of a dissertation reflect the flow of the overall research process . This is essential to understand, as each chapter will make a lot more sense if you “get” this concept. If you’re not familiar with the research process, read this post before going further.

Right. Now that we’ve covered the big picture, let’s dive a little deeper into the details of each section and chapter. Oh and by the way, you can also grab our free dissertation/thesis template here to help speed things up.

The title page of your dissertation is the very first impression the marker will get of your work, so it pays to invest some time thinking about your title. But what makes for a good title? A strong title needs to be 3 things:

  • Succinct (not overly lengthy or verbose)
  • Specific (not vague or ambiguous)
  • Representative of the research you’re undertaking (clearly linked to your research questions)

Typically, a good title includes mention of the following:

  • The broader area of the research (i.e. the overarching topic)
  • The specific focus of your research (i.e. your specific context)
  • Indication of research design (e.g. quantitative , qualitative , or  mixed methods ).

For example:

A quantitative investigation [research design] into the antecedents of organisational trust [broader area] in the UK retail forex trading market [specific context/area of focus].

Again, some universities may have specific requirements regarding the format and structure of the title, so it’s worth double-checking expectations with your institution (if there’s no mention in the brief or study material).

Dissertations stacked up

Acknowledgements

This page provides you with an opportunity to say thank you to those who helped you along your research journey. Generally, it’s optional (and won’t count towards your marks), but it is academic best practice to include this.

So, who do you say thanks to? Well, there’s no prescribed requirements, but it’s common to mention the following people:

  • Your dissertation supervisor or committee.
  • Any professors, lecturers or academics that helped you understand the topic or methodologies.
  • Any tutors, mentors or advisors.
  • Your family and friends, especially spouse (for adult learners studying part-time).

There’s no need for lengthy rambling. Just state who you’re thankful to and for what (e.g. thank you to my supervisor, John Doe, for his endless patience and attentiveness) – be sincere. In terms of length, you should keep this to a page or less.

Abstract or executive summary

The dissertation abstract (or executive summary for some degrees) serves to provide the first-time reader (and marker or moderator) with a big-picture view of your research project. It should give them an understanding of the key insights and findings from the research, without them needing to read the rest of the report – in other words, it should be able to stand alone .

For it to stand alone, your abstract should cover the following key points (at a minimum):

  • Your research questions and aims – what key question(s) did your research aim to answer?
  • Your methodology – how did you go about investigating the topic and finding answers to your research question(s)?
  • Your findings – following your own research, what did do you discover?
  • Your conclusions – based on your findings, what conclusions did you draw? What answers did you find to your research question(s)?

So, in much the same way the dissertation structure mimics the research process, your abstract or executive summary should reflect the research process, from the initial stage of asking the original question to the final stage of answering that question.

In practical terms, it’s a good idea to write this section up last , once all your core chapters are complete. Otherwise, you’ll end up writing and rewriting this section multiple times (just wasting time). For a step by step guide on how to write a strong executive summary, check out this post .

what is the meaning of the word dissertation

Table of contents

This section is straightforward. You’ll typically present your table of contents (TOC) first, followed by the two lists – figures and tables. I recommend that you use Microsoft Word’s automatic table of contents generator to generate your TOC. If you’re not familiar with this functionality, the video below explains it simply:

If you find that your table of contents is overly lengthy, consider removing one level of depth. Oftentimes, this can be done without detracting from the usefulness of the TOC.

Right, now that the “admin” sections are out of the way, its time to move on to your core chapters. These chapters are the heart of your dissertation and are where you’ll earn the marks. The first chapter is the introduction chapter – as you would expect, this is the time to introduce your research…

It’s important to understand that even though you’ve provided an overview of your research in your abstract, your introduction needs to be written as if the reader has not read that (remember, the abstract is essentially a standalone document). So, your introduction chapter needs to start from the very beginning, and should address the following questions:

  • What will you be investigating (in plain-language, big picture-level)?
  • Why is that worth investigating? How is it important to academia or business? How is it sufficiently original?
  • What are your research aims and research question(s)? Note that the research questions can sometimes be presented at the end of the literature review (next chapter).
  • What is the scope of your study? In other words, what will and won’t you cover ?
  • How will you approach your research? In other words, what methodology will you adopt?
  • How will you structure your dissertation? What are the core chapters and what will you do in each of them?

These are just the bare basic requirements for your intro chapter. Some universities will want additional bells and whistles in the intro chapter, so be sure to carefully read your brief or consult your research supervisor.

If done right, your introduction chapter will set a clear direction for the rest of your dissertation. Specifically, it will make it clear to the reader (and marker) exactly what you’ll be investigating, why that’s important, and how you’ll be going about the investigation. Conversely, if your introduction chapter leaves a first-time reader wondering what exactly you’ll be researching, you’ve still got some work to do.

Now that you’ve set a clear direction with your introduction chapter, the next step is the literature review . In this section, you will analyse the existing research (typically academic journal articles and high-quality industry publications), with a view to understanding the following questions:

  • What does the literature currently say about the topic you’re investigating?
  • Is the literature lacking or well established? Is it divided or in disagreement?
  • How does your research fit into the bigger picture?
  • How does your research contribute something original?
  • How does the methodology of previous studies help you develop your own?

Depending on the nature of your study, you may also present a conceptual framework towards the end of your literature review, which you will then test in your actual research.

Again, some universities will want you to focus on some of these areas more than others, some will have additional or fewer requirements, and so on. Therefore, as always, its important to review your brief and/or discuss with your supervisor, so that you know exactly what’s expected of your literature review chapter.

Dissertation writing

Now that you’ve investigated the current state of knowledge in your literature review chapter and are familiar with the existing key theories, models and frameworks, its time to design your own research. Enter the methodology chapter – the most “science-ey” of the chapters…

In this chapter, you need to address two critical questions:

  • Exactly HOW will you carry out your research (i.e. what is your intended research design)?
  • Exactly WHY have you chosen to do things this way (i.e. how do you justify your design)?

Remember, the dissertation part of your degree is first and foremost about developing and demonstrating research skills . Therefore, the markers want to see that you know which methods to use, can clearly articulate why you’ve chosen then, and know how to deploy them effectively.

Importantly, this chapter requires detail – don’t hold back on the specifics. State exactly what you’ll be doing, with who, when, for how long, etc. Moreover, for every design choice you make, make sure you justify it.

In practice, you will likely end up coming back to this chapter once you’ve undertaken all your data collection and analysis, and revise it based on changes you made during the analysis phase. This is perfectly fine. Its natural for you to add an additional analysis technique, scrap an old one, etc based on where your data lead you. Of course, I’m talking about small changes here – not a fundamental switch from qualitative to quantitative, which will likely send your supervisor in a spin!

You’ve now collected your data and undertaken your analysis, whether qualitative, quantitative or mixed methods. In this chapter, you’ll present the raw results of your analysis . For example, in the case of a quant study, you’ll present the demographic data, descriptive statistics, inferential statistics , etc.

Typically, Chapter 4 is simply a presentation and description of the data, not a discussion of the meaning of the data. In other words, it’s descriptive, rather than analytical – the meaning is discussed in Chapter 5. However, some universities will want you to combine chapters 4 and 5, so that you both present and interpret the meaning of the data at the same time. Check with your institution what their preference is.

Now that you’ve presented the data analysis results, its time to interpret and analyse them. In other words, its time to discuss what they mean, especially in relation to your research question(s).

What you discuss here will depend largely on your chosen methodology. For example, if you’ve gone the quantitative route, you might discuss the relationships between variables . If you’ve gone the qualitative route, you might discuss key themes and the meanings thereof. It all depends on what your research design choices were.

Most importantly, you need to discuss your results in relation to your research questions and aims, as well as the existing literature. What do the results tell you about your research questions? Are they aligned with the existing research or at odds? If so, why might this be? Dig deep into your findings and explain what the findings suggest, in plain English.

The final chapter – you’ve made it! Now that you’ve discussed your interpretation of the results, its time to bring it back to the beginning with the conclusion chapter . In other words, its time to (attempt to) answer your original research question s (from way back in chapter 1). Clearly state what your conclusions are in terms of your research questions. This might feel a bit repetitive, as you would have touched on this in the previous chapter, but its important to bring the discussion full circle and explicitly state your answer(s) to the research question(s).

Dissertation and thesis prep

Next, you’ll typically discuss the implications of your findings . In other words, you’ve answered your research questions – but what does this mean for the real world (or even for academia)? What should now be done differently, given the new insight you’ve generated?

Lastly, you should discuss the limitations of your research, as well as what this means for future research in the area. No study is perfect, especially not a Masters-level. Discuss the shortcomings of your research. Perhaps your methodology was limited, perhaps your sample size was small or not representative, etc, etc. Don’t be afraid to critique your work – the markers want to see that you can identify the limitations of your work. This is a strength, not a weakness. Be brutal!

This marks the end of your core chapters – woohoo! From here on out, it’s pretty smooth sailing.

The reference list is straightforward. It should contain a list of all resources cited in your dissertation, in the required format, e.g. APA , Harvard, etc.

It’s essential that you use reference management software for your dissertation. Do NOT try handle your referencing manually – its far too error prone. On a reference list of multiple pages, you’re going to make mistake. To this end, I suggest considering either Mendeley or Zotero. Both are free and provide a very straightforward interface to ensure that your referencing is 100% on point. I’ve included a simple how-to video for the Mendeley software (my personal favourite) below:

Some universities may ask you to include a bibliography, as opposed to a reference list. These two things are not the same . A bibliography is similar to a reference list, except that it also includes resources which informed your thinking but were not directly cited in your dissertation. So, double-check your brief and make sure you use the right one.

The very last piece of the puzzle is the appendix or set of appendices. This is where you’ll include any supporting data and evidence. Importantly, supporting is the keyword here.

Your appendices should provide additional “nice to know”, depth-adding information, which is not critical to the core analysis. Appendices should not be used as a way to cut down word count (see this post which covers how to reduce word count ). In other words, don’t place content that is critical to the core analysis here, just to save word count. You will not earn marks on any content in the appendices, so don’t try to play the system!

Time to recap…

And there you have it – the traditional dissertation structure and layout, from A-Z. To recap, the core structure for a dissertation or thesis is (typically) as follows:

  • Acknowledgments page

Most importantly, the core chapters should reflect the research process (asking, investigating and answering your research question). Moreover, the research question(s) should form the golden thread throughout your dissertation structure. Everything should revolve around the research questions, and as you’ve seen, they should form both the start point (i.e. introduction chapter) and the endpoint (i.e. conclusion chapter).

I hope this post has provided you with clarity about the traditional dissertation/thesis structure and layout. If you have any questions or comments, please leave a comment below, or feel free to get in touch with us. Also, be sure to check out the rest of the  Grad Coach Blog .

Dissertation vs. Thesis—What’s the Difference?

Matt Ellis

If you’re confused about the meaning of dissertation versus thesis , you’re not alone. These two types of academic writing have a lot in common, but their meanings are reversed in American and British English. Depending on where you are in the world, the differences between a dissertation and a thesis might change!

What is a dissertation vs. a thesis?

In American English, a dissertation is a research paper that’s required to earn a doctorate degree, while a thesis is a research paper required to earn a master’s degree. Dissertations and theses (the plural of thesis ) are often mixed up because they’re both lengthy research papers written for higher education, especially as part of a master’s or doctorate program. A thesis or dissertation is often a requirement for obtaining an academic degree, and both are usually seen as a gatekeeper for becoming eligible to graduate.

Informally the words dissertation and thesis are often used interchangeably, which only adds to the confusion. However, in the formal academic world, their meanings are different, although some universities occasionally have their own unique definitions. Let’s take a look at what dissertation and thesis actually mean.

What is a dissertation?

In American English, a dissertation is a highly involved research paper written as a requirement to earn a doctorate degree. When we say “highly involved,” we mean it; dissertations run 300 pages or more, essentially becoming a book-length research paper.

The central attribute of a dissertation is original research: To earn a doctorate, a person must submit new discoveries and data to their chosen field. This is symbolic of becoming part of a body of academic knowledge, and a systemic way to encourage the advancement of science.

In scientific fields of study, dissertations are empirical , drawing on data collected by the writer. In less-scientific fields, like literature or philosophy, dissertations are nonempirical : Instead of new data, “original research” is replaced by innovative new ideas, interpretations, analyses, or perspectives.

Dissertation may also involve what’s known as a dissertation defense , an oral presentation in front of a panel of experts, in addition to the paper. In a dissertation defense, the experts ask questions about the findings to test their validity, and the student must “defend” their research by explaining their methods and reasoning. The panel then decides whether or not the student graduates and earns their degree.

What is a thesis?

In American English, a thesis paper is a lengthy research paper written as a requirement to earn a master’s degree (or sometimes a bachelor’s degree, depending on the university). Also referred to as a “senior thesis” for undergraduate courses, these papers are written at the end of a program as a culmination of their studies, similar to dissertations.

Unlike a dissertation, a thesis doesn’t necessarily involve original research or ideas, although many master’s theses do. Generally, a thesis is less about adding to a body of knowledge, and more about testing a student’s skills in research, comprehension, or analysis. Regardless, a thesis paper is still a considerable amount of work and requires more effort than a standard academic paper.

Dissertation vs. thesis in American and British English

We’ve talked before about how British English and American English are different , and the definitions of dissertation versus thesis are just another example.

In short, the meanings are reversed: In British English, the term dissertation is used for bachelor’s and master’s programs, whereas thesis is used for doctorates. Keep in mind that academic institutions are very different in the US and the UK, not to mention in each individual English-speaking country, so what’s involved in a bachelor’s, master’s, and doctorate program is also different.

It’s important to remember that the words dissertation and thesis are frequently used interchangeably, so the technical definitions are just for formal situations—like when submitting one or the other. If you’re confused, you can also ask your adviser. Each school or institution may have their own definitions of the terms.

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.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation , it’s a list of all terms you used that may not immediately be obvious to your reader.

Your glossary only needs to include terms that your reader may not be familiar with, and it’s intended to enhance their understanding of your work. Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one.

If you do choose to include a glossary, it should go at the beginning of your document, just after the table of contents and (if applicable) list of tables and figures or list of abbreviations . It’s helpful to place your glossary at the beginning, so your readers can familiarize themselves with key terms relevant to your thesis or dissertation topic prior to reading your work. Remember that glossaries are always in alphabetical order.
