How to Write a Dissertation

What is a Dissertation?

A dissertation is not a bigger version of an assignment. It is a full research project where you choose one focused topic, write a research question, and is based on the aims and objectives of the study.

  • It is usually a 10,000 to 15,000-word project

This includes main body content, in-text citations, tables and footnotes, and excludes bibliography, appendix, consent form and interview questions.

  • Requires extensive research

This means you have to read proper academic sources first, for e.g. books, journal articles, reports and studies, then use them as reference to support what you write in the dissertation.

  • It usually has 5 chapters

These chapters include Introduction, Literature Review, Research Methodology, Findings and Discussion, Conclusion.

  • Must follow the university’s formatting instructions

You must follow the instructions provided to you in your dissertation brief to properly format your dissertation. You may lose marks for not following the formatting guidelines.

  • Word count is a limit, not a target to fill

A 10,000-word dissertation limit means you should not go over 10,000 words; it does not mean you should add unnecessary content to reach that number.

  • It is 25% to 50% of the Final Mark

At many UK universities, the dissertation can make up around 25% to 50% of the final-year marks, so it is not a project students can treat lightly.

  • 30-credit dissertation out of 120 final-year credits = 25%
  • 40-credit dissertation out of 120 final-year credits = 33%
  • 60-credit dissertation out of 120 final-year credits = 50%

Dissertation Structure

Dissertation structure means the order in which a dissertation is written. It shows where each part of the research should go. It helps your supervisor read and follow your work easily. The dissertation is divided into 5 chapters which are listed below:

Chapter 1 - Introduction

The introduction chapter explains the topic and sets the research aim and objectives along with the research question.

Chapter 2 - Literature Review

The literature review discusses previous research, including what earlier studies found, where researchers agree or disagree, and what gap still remains in the topic. The reader must know what is already known before your own research begins.

Chapter 3 - Research Methodology

The methodology chapter tells the reader how the research was done. It explains whether the dissertation used surveys, interviews, case studies or secondary data, and why that approach was the right choice for the topic.

Chapter 4 - Findings and Discussion

The findings and discussion chapter presents the research results and explains what they mean for the dissertation topic.

Chapter 5 - Conclusion

The conclusion chapter brings the dissertation together by explaining the main findings and answering the research question.

Before You Start Writing Your Dissertation

  • Check the deadline first. Not the date only, but the exact time.
  • Do not leave Turnitin for the last few minutes. Uploading, converting, slow internet, wrong file, login issue, any of these can make the work late.
  • One minute late can still count as late. The deduction is not the same in every university. Some deduct a percentage, some deduct marks, and some give zero after a certain time. The University of Manchester says work submitted 1 minute past the deadline can be treated as late, York lists 5% deduction up to one hour late, and Westminster says 10 marks can be deducted within 24 hours.
  • So do not write “25% will be deducted” unless your own university brief says that. The safer rule is simple: submit early because late means penalty.
  • Check if Turnitin allows late submission at all. Turnitin says late submission only works if the instructor has enabled it.

How to Write a Dissertation? Chapter by Chapter Guide

Writing a dissertation becomes easier when you know what each chapter is supposed to do. This guide explains how to write a dissertation from Chapter 1 introduction to Chapter 5 conclusion, word count planning, and the parts students often misunderstand.

Before you write Chapter 1, check your dissertation handbook or module guide. It will usually tell you the required structure, word count, referencing style, deadline and marking criteria. These rules decide how your dissertation should be planned before the writing starts.

How to Write Chapter 1: Introduction

  • Open with your topic, but narrow it quickly. Do not spend half the chapter telling the full background of the subject.
  • Say what problem your dissertation is dealing with. The reader should know what issue made this research worth doing.
  • Write one clear aim. It should say exactly what your dissertation is trying to find out.
  • Add 3–5 objectives. These should break the aim into smaller parts, not repeat the same thing in different words.
  • Write a research question that your data can actually answer. Do not write a question that needs data you cannot collect.
  • Explain why the topic matters, but keep it close to your course, sector, country, company or chosen group.
  • Add the scope. Say what your dissertation covers and what it does not cover.
  • End with a short chapter outline so the marker knows how the dissertation will move forward.

How to Write Chapter 2: Literature Review

  • Do not write one paragraph for every article you read. That looks like notes, not a literature review.
  • The University of Leeds also explains that a literature review helps narrow the project, shape the research question and decide the method.
  • Divide the chapter into themes that match your research question.
  • Use sources that help your argument. Do not add a source only because it has the same keyword as your topic.
  • Compare authors. Show where they say the same thing and where they do not agree.
  • Point out what is missing in the research. This is where your own dissertation starts to make sense.
  • Use theories or models only if they help explain your topic. Do not add them just to make the chapter look academic.
  • Keep bringing the discussion back to your own research question.
  • Finish by showing the gap your dissertation is trying to cover.

How to Write Chapter 3: Methodology

  • Start by saying what type of research you used: qualitative, quantitative or mixed.
  • Explain why that method fits your research question. Do not just name the method and move on.
  • Say how you collected the data, such as survey, interviews, reports, case study or secondary sources.
  • Explain where the data came from and why that source was suitable.
  • Mention the sample size and how you selected it.
  • Explain how the data was analysed. For example, SPSS, Excel, thematic analysis or another method.
  • Add ethics. Mention consent, privacy, anonymity and how the data was handled.
  • Be honest about the limits of your method. No method is perfect.

How to Write Chapter 4: Findings and Discussion

  • Show the results that answer your research question. Do not include results just to fill space.
  • If you use tables or charts, explain what they mean in words.
  • Arrange the findings by theme, objective, variable or research question.
  • After each main finding, explain why it matters.
  • Link the findings back to the literature review. Say whether your results support or challenge previous studies.
  • Do not force weak results to look strong.
  • The University of Manchester Academic Phrasebank gives examples of cautious academic language. This is useful in Chapter 4 because findings should not sound stronger than the data allows.
  • Use careful wording such as suggests, indicates or may show when the data is limited.
  • Keep the discussion close to your actual findings, not what you hoped to find.

How to Write Chapter 5: Conclusion and Recommendations

  • Start by returning to your main aim.
  • Say whether the aim was answered.
  • Answer each objective briefly, using what you found in Chapter 4.
  • Do not introduce a new argument in the conclusion.
  • Give recommendations only if they come from your findings.
  • Mention the limits of your study, such as sample size, time, access to data or one-sector focus.
  • Add future research only where it makes sense.
  • End with a clear final answer to the dissertation topic.

Check the Marks and Word Count

Do not give every chapter the same space. A short introduction and a weak findings chapter can damage the whole dissertation.

For a 10,000-word dissertation, a balanced split can look like this:

ChapterWhat It CoversRough Word CountRough Share
Chapter 1: Introduction Topic, problem, aim, objectives, research question 1,000–1,500 10–15%
Chapter 2: Literature Review Existing research, themes, arguments, research gap 2,500–3,000 25–30%
Chapter 3: Methodology Research design, data collection, sampling, ethics, analysis method 1,500–2,000 15–20%
Chapter 4: Findings and Discussion Results, themes, tables, analysis, link back to research question 2,500–3,000 25–30%
Chapter 5: Conclusion and Recommendations Final answer, recommendations, limits of the study 500–1,000 5–10%

Your university marking guide comes first. If your brief says Chapter 2 is 4,000 words or Chapter 1 carries 20%, follow that. But do not make the literature review huge just because it feels easier to write. The findings and discussion chapter usually needs enough space because that is where your own work is shown.

If your dissertation includes a presentation, poster or PowerPoint slides, check whether it has separate marks. Do not assume it is only extra work with no marks.

Know Who Is Reading Your Dissertation

  • Your dissertation is not read slowly like a book.
  • Your supervisor or marker may have many dissertations to check in the same week.
  • Do not make them search for your point.
  • From the start, they should understand:
    • what you are researching
    • why you are researching it
    • how you are doing it
    • what question you are trying to answer
  • If this is not clear, the dissertation starts looking weak even before the main chapters begin.
  • A good dissertation does not hide the main idea. It tells the reader the direction early, then keeps following that direction chapter by chapter.

What Comes Before Chapter 1?

Before the table of contents and chapters, most dissertations have front pages.

These usually include:

  • title page
  • declaration page
  • acknowledgements
  • abstract
  • table of contents
  • list of tables
  • list of figures
  • list of abbreviations, if needed

The abstract comes near the top, but write it at the end. It is a short summary of the full dissertation, so you cannot write it properly before finishing the work.

Your abstract should say:

  • what the topic is
  • what the aim was
  • what method was used
  • what the main findings were
  • what conclusion you reached

Do not turn the abstract into a long introduction. Keep it direct.

Start Writing at Least 3 Weeks Before Submission

  • Start writing at least 3 weeks before the deadline.
  • Three weeks is still tight, but it gives you time to write, receive feedback, fix references and submit without panic.
  • Do not send your supervisor the full dissertation one day before the deadline.
  • Supervisors can take around a week to reply, especially when many students are submitting work.
  • Send chapters in parts if your supervisor allows it.
  • When feedback comes back, make the changes properly before sending the work again.
  • Do not ignore feedback and then expect the final version to improve by itself.

Final Checks Before Submitting Your Dissertation

  • Read the full dissertation yourself before submitting.
  • Do not only check spelling. Check whether the chapters actually connect.
  • Chapter 1 should introduce the same research question that Chapter 4 answers.
  • Chapter 2 should not be a random list of sources. See dissertation literature review mistakes
  • Chapter 3 should explain the method you actually used.
  • Chapter 4 should not dump tables without explaining them.
  • Chapter 5 should not add new arguments that were never discussed earlier.
Some students understand the steps but still struggle to manage the comprehensive research, writing, editing and formatting. If that happens, our full dissertation writing help can support the work from topic to final checks.

If Your Dissertation Has a Presentation

Some dissertations also include a presentation or PowerPoint slides.

Do not copy full paragraphs from your dissertation into the slides.

Your slides should cover:

  • topic
  • aim and research question
  • method
  • main findings
  • conclusion
  • recommendations
  • limitations

The presentation should show that you understand your own dissertation. Keep the slides short and explain the details while speaking.

Use Clear Academic Language

Do not try to make every sentence sound difficult.

Clear writing is better than heavy wording.

Use careful words when discussing findings.

For example:

  • write “The findings suggest” instead of “This proves”
  • write “This may show” when the result is not final
  • write “The data indicates” when you are explaining a pattern

Keep the same words throughout the dissertation. If you write “employee performance” in Chapter 1, do not suddenly call it “workplace productivity” in Chapter 4 unless you explain the change.

Every chapter should stay close to the research question. If a paragraph does not help answer the research question, it probably does not belong in the dissertation.
