Key takeaways
- The standard empirical dissertation has five chapters: introduction, literature review, methodology, results and discussion, often with a separate conclusion.
- Each chapter has a single job. The structure works when each one hands a clear conclusion to the next.
- Typical proportions: introduction 10%, literature review 20–30%, methodology 15–20%, results 15–20%, discussion and conclusion 20–25%.
- Qualitative, humanities and article-based theses use different structures, so check what your discipline expects.
- Your university's template and handbook override any general outline, especially for front matter and formatting.
How should a dissertation be structured?
A typical empirical dissertation is structured in five chapters: an introduction that states the problem and research questions, a literature review that establishes the gap, a methodology that explains how you investigated it, a results chapter that reports what you found, and a discussion (often with a separate conclusion) that interprets the findings and states your contribution. These chapters sit between front matter (title page, abstract, contents) and back matter (references, appendices).
This IMRaD-style shape (Introduction, Methods, Results and Discussion) is standard in the sciences, social sciences, health and business. Humanities and some qualitative projects organise chapters around themes or arguments instead, which is covered further down.
The full dissertation outline at a glance
The table shows each component in order, with its job and a typical share of the main text. Percentages are a guide for a 15,000-word master's dissertation; front and back matter are usually excluded from the word count.
| Part | Its job | Typical share | In 15,000 words |
|---|---|---|---|
| Title page, abstract, acknowledgements, contents, lists of tables and figures | Orient the reader | Not counted | Abstract 200–350 words |
| 1. Introduction | Problem, aims, questions, roadmap | about 10% | 1,500 |
| 2. Literature review | What is known; the gap; theoretical framework | 20–30% | 3,500–4,000 |
| 3. Methodology | Design, sample, instruments, analysis, ethics | 15–20% | 2,500–3,000 |
| 4. Results or findings | What you found, organised by question | 15–20% | 2,500–3,000 |
| 5. Discussion | What it means, comparison with literature, limitations | 15–20% | 2,500–3,000 |
| 6. Conclusion | Direct answer, contribution, recommendations | 5–10% | 1,000 |
| References and appendices | Sources; instruments, extra tables, consent forms | Not counted | As needed |
So how many chapters does a dissertation have? Five or six in this standard model. Some programmes merge results and discussion into one chapter or fold the conclusion into the discussion, giving four or five.
What goes in each chapter
Chapter 1: introduction
Open with the real-world or scholarly problem, narrow quickly to the specific gap, state your aim and research questions, explain why answering them matters, define key terms and close with a short outline of the remaining chapters. Our guide on how to write research questions shows how to phrase them.
Chapter 2: literature review
Organise by theme, debate or concept rather than by author. Each section should end by saying what the literature does not yet tell us. Close with the theoretical or conceptual framework that shapes your study and, for quantitative work, your hypotheses.
Chapter 3: methodology
Describe and justify your research design, population and sampling, instruments or sources, procedure, analysis techniques, and how you addressed validity or trustworthiness and ethics. Someone reading this chapter should be able to repeat your study.
Chapter 4: results or findings
Report what you found in the order of your research questions. In quantitative work, give descriptive statistics first, then the tests that answer each question. In qualitative work, present themes with representative quotations. Interpretation is saved for the next chapter.
Chapter 5: discussion
Answer each research question in words, relate the answers to the studies in your literature review, offer explanations for unexpected results, acknowledge limitations and set out implications for theory and practice.
Chapter 6: conclusion
Briefly restate the problem, give the direct answer, name your contribution in one or two sentences and suggest focused directions for future research. No new data or citations belong here.

Front matter and back matter
These parts are short but are often checked strictly against the university's formatting rules.
- Title page: title, your name, degree, department, institution, date and sometimes supervisor. Use your university's exact layout.
- Abstract: a single paragraph (sometimes structured) summarising the whole study, usually 150–350 words. See our guide on writing a dissertation abstract.
- Acknowledgements: optional and personal; keep it brief.
- Table of contents and lists of tables and figures: generate them automatically from heading and caption styles in your word processor.
- List of abbreviations: useful if you use many acronyms.
- References: every source cited in the text, formatted in your required style (APA 7, Harvard, Chicago and so on), and nothing that is not cited.
- Appendices: questionnaires, interview guides, ethics approval, consent forms, extra tables and code. Label them (Appendix A, B, C) and refer to each in the main text.
A sample dissertation outline
Here is an outline for an invented quantitative master's study, Paid work hours and burnout among final-year undergraduates. Notice how the subheadings already sketch the argument.
- Introduction
- 1.1 Rising term-time employment among undergraduates
- 1.2 Burnout as a student wellbeing concern
- 1.3 Research aim and questions
- 1.4 Significance for universities and student services
- 1.5 Structure of the dissertation
- Literature review
- 2.1 Defining and measuring academic burnout
- 2.2 Term-time work and academic outcomes
- 2.3 Job demands–resources theory as a framework
- 2.4 The gap: final-year students and hours thresholds
- 2.5 Hypotheses
- Methodology
- 3.1 Cross-sectional survey design
- 3.2 Participants and sampling
- 3.3 Measures
- 3.4 Procedure and ethics
- 3.5 Analysis plan
- Results
- 4.1 Sample characteristics
- 4.2 Work hours and burnout (RQ1)
- 4.3 The role of perceived flexibility (RQ2)
- Discussion
- 5.1 Interpreting the main findings
- 5.2 Comparison with previous research
- 5.3 Limitations
- 5.4 Implications for practice
- Conclusion
A good test of any outline: read only the headings and ask whether a stranger could tell what you studied, how and what you concluded.
How to plan your own outline
- Write your main research question and sub-questions at the top of a blank page.
- Add the six chapter headings and a target word count for each, using the proportions in the table above.
- Under each chapter, list three to six subheadings. In the literature review, these should be themes or debates; in the results, one subheading per research question.
- Under each subheading, write one sentence stating the point that section will make. If you cannot, you need to read or analyse more before writing it.
- Share the outline with your supervisor or advisor before drafting. Agreeing the structure first prevents large rewrites later.
Treat the outline as a living document. It will change as your analysis develops, and updating it is quicker than reorganising a full draft.
How structure changes by discipline and format
The five-chapter model is not universal. Common variations include:
| Format | Typical structure |
|---|---|
| Qualitative social science | Often the same chapters, but findings are presented theme by theme and may be integrated with discussion |
| Humanities (history, literature, philosophy) | Introduction (with literature and approach), three to five argument-led chapters, conclusion. Methods are discussed within the introduction |
| Thesis by publication | Introduction and literature context, three or so article chapters (each with its own methods and results), integrative discussion, conclusion |
| Mixed methods | Either separate results chapters for each strand, or chapters organised by research question with both strands integrated |
| Lab-based sciences | Sometimes one chapter per experiment or study, each with mini-methods and results, framed by a general introduction and discussion |
When in doubt, look at three or four recently accepted theses from your own department in the institutional repository. They are the most reliable template you will find.
Common structural problems and how to fix them
- Results that interpret, discussions that repeat. Move interpretation out of the results chapter and replace repeated numbers in the discussion with what they mean.
- A literature review that never arrives at a gap. Add a closing paragraph to each section that names what is missing, then a final section that states the gap your study fills.
- Research questions that change between chapters. Use identical wording in the introduction, methodology, results and discussion.
- Methods that do not match the results. Every analysis reported in chapter 4 should be announced in chapter 3, and vice versa.
- A conclusion that introduces new material. If it is new, it belongs in the discussion.
- Chapters with no signposting. Open each chapter with two or three sentences saying what it does and close it with a short summary that leads into the next. These links are what make a thesis read as one argument rather than six separate essays.
