How to write a dissertation, chapter by chapter

1Before chapter one: the proposal

Most dissertations start with a proposal: a short document that sets out your research question, why it matters, what has already been written about it, and how you plan to answer it. Departments use it to approve the topic and match you with a supervisor. You use it as a plan.

Treat the proposal as more than a hurdle. The question you write in it will shape every chapter, so spend time making it narrow enough to answer with the time, data and word count you have. A question that would need a team of researchers and three years is a common reason a dissertation stalls in month two. Our research proposal guide walks through each section with a template.

2Introduction

The introduction tells the reader what the dissertation is about, why it matters, what it sets out to find, and how it is organised. The University of Westminster's dissertation guide lists the usual contents: the topic and why it is of interest, background and the main debates, what the existing literature has not yet said, your aim and research question or hypothesis, your approach and methods, and a short outline of the chapters that follow. It suggests the introduction is roughly 10 per cent of the word count.

Draft a short version early so you know where you are going, then rewrite it at the end. By then you know what you actually found, and the introduction should promise exactly that.

3Literature review

The literature review shows what is already known about your topic and where your research fits. It is not a list of summaries. Group the sources by theme or debate, show where they agree and disagree, and end on the gap your question addresses. Westminster's guide describes the usual movement: from general background and concepts towards your specific focus, ending with what the literature does not yet cover.

By the end of the chapter a reader should be able to say what the field has argued, where it falls short, and how your question responds. Some courses fold the review into the introduction, so check your handbook. For a step-by-step method, read how to write a literature review.

4Methodology

The methodology chapter explains how you answered the question and why that design was the right one. It should cover what you did, with whom or what, where and when, the reasons for each choice, and the limitations of your approach. If you collected data from people, this is also where your ethics approval and consent process belong.

The test of a good methodology chapter is whether another researcher could repeat your study from it, and whether a sceptical reader would accept that your method can actually answer your question. Be honest about the limits. Markers trust a chapter that names its weaknesses more than one that claims to have none.

5Results and discussion

The results chapter reports what you found. The University of Southampton's dissertation guide describes it as a direct, factual account of the data, written without interpretation, with tables and figures where they help. Report the key findings, including the ones you did not expect. Leaving out awkward data undermines the rest of your work.

The discussion interprets those findings. It returns to the literature from your review, explains what the results show, answers your research question or tests your hypothesis, and considers the limitations that only became visible once the data was in. Southampton frames its central question as "What do we now know that we didn't before?" It is usually the most original chapter you write.

Some dissertations combine the two into one chapter, presenting a set of results and discussing it before moving to the next. Others, especially in the humanities, have no separate results chapter at all and argue through thematic chapters instead. Follow your department's convention.

Two mistakes to avoid: introducing a finding for the first time in the discussion, and overstating what your results prove. A small study can still matter. Say what it shows, and no more.

6Conclusion

The conclusion draws the dissertation together. Summarise and connect your main findings, say how they answer your research question, and explain why they matter for the field, including what future research could do next. Westminster suggests a conclusion is roughly 5 to 10 per cent of the word count and should not introduce new ideas, theories or data.

Read your introduction and conclusion one after the other before you submit. They should frame the dissertation: the conclusion should answer the question the introduction asked, in the same terms.

7Abstract, contents, references and appendices

Around the chapters sit the parts markers check first and students leave to last. Westminster's guide lists the usual order: title page, abstract and table of contents at the front; bibliography and appendices at the back.

The abstract is a short summary of the whole project: the question, the method, the main findings and what they mean. Write it last, when you know what you found, and keep it to the length your handbook sets. The table of contents is far easier if you use your word processor's heading styles from the first draft, so page numbers update themselves every time you edit.

The references list every source you cited, in the style your department uses. Build it as you read rather than in the final week. Appendices hold material that supports the dissertation but would interrupt the main text, such as interview transcripts, survey questions or extra tables. Number each one, give it a title, and refer to each appendix at least once in the text, or the marker has no reason to look at it.

8A timeline that works

Dissertations go wrong in the middle, not at the end. The most reliable plan works backwards from the submission date and leaves real time for revision. This is a planning suggestion for a dissertation written over about six months alongside other study; adjust it to your own deadlines.

Write as you go. A methodology drafted while the method is fresh in your mind takes a fraction of the time it takes three months later.

9Working with your supervisor

Your supervisor is there to guide the project, not to write it. Most will read a plan, comment on draft chapters and tell you when the argument drifts. Find out early how much they will read, how quickly they reply, and how they prefer to receive drafts.

Make meetings count. Send work a few days ahead, bring two or three specific questions, and write down what was agreed. If you are stuck, say so early. A supervisor can rescue a narrowed question in month two far more easily than a missing chapter in month six.

Be clear about other help too. Many universities allow proofreading of a dissertation within limits, and some require you to declare it. Read proofreading, editing or ghostwriting before anyone else touches your draft.
