# IB Extended Essay Guide: Choosing a Topic, Structure and Timeline

**The short answer:** The IB Extended Essay is a 4,000-word research paper graded A to E. Choose a narrow, researchable question in a subject you know, finish topic selection by the end of Grade 11, and do your research over the summer. An E fails the Diploma, so plan carefully.

For most students in the IB Diploma Programme, the Extended Essay is one of the least understood requirements of the two years. Each student writes a 4,000-word independent research paper in a subject of their choice, and it influences the final diploma score through the EE/TOK matrix. Students at schools such as Upper Canada College, Havergal College, Branksome Hall and Crescent School usually hear about it in Grade 11, yet many families reach the research stage with no clear plan. This guide explains what the essay demands, how to pick a topic that suits your strengths, and what makes the difference between a solid essay and an outstanding one.

## How the Extended Essay Is Graded

Every IB Diploma student must complete the Extended Essay, a 4,000-word independent research essay. It goes to the IB for external assessment and receives a grade from A (highest) to E (lowest). A student who gets an E does not earn the Diploma, whatever their other scores, so it pays to take the essay seriously from the outset.

This guide describes the current Extended Essay, first assessed in May 2027. It is marked out of 30 on five criteria: framework for the essay (6 marks), knowledge and understanding (6), analysis and line of argument (6), discussion and evaluation (8) and reflection (4). Reflection is judged through a 500-word reflective statement on the Reflection and Progress Form (RPF), which the student writes after the final reflection session with their supervisor.

Paired with the Theory of Knowledge grade, the EE contributes up to three bonus points to the total IB score. An A in each earns three points, while an E in either one means the Diploma is failed. From our experience with IB students across Canada and the US, those who earn the top EE grades treat it as a real research project, not a writing assignment.

## Choosing a Strong Topic

The best topics are specific, researchable and truly interesting to the student. A frequent error is picking a topic that is too broad or that relies only on secondary sources.

Experienced IB educators suggest the following:

- **Pick a subject you already take at HL.** Knowing the subject well is a big advantage. Your background knowledge speeds up the research and sharpens the analysis.
- **Narrow the research question before you start.** “The impact of social media on teenagers” is far too broad. “Is mindfulness or cognitive behavioural therapy the more effective way for teenagers to cope with exam stress?” is focused and can be answered from published research.
- **Think about primary sources.** For a science topic, can you run experiments at school? For history, can you get the archival material you need? Primary research nearly always makes an EE stronger.
- **Talk to your supervisor early.** The supervisor has to approve your research question, so choose someone with real interest and expertise in the area.

IB coordinators report that the main reason students earn a C or lower is a research question too vague to produce meaningful analysis. An extra week spent refining the question at the start will save a lot of time later.

## Structuring the Essay

A well-organized EE uses a clear academic format: introduction, body sections, conclusion and bibliography. Details differ a little from subject to subject, but the principles are the same in every IB subject group.

A recommended layout for most essays:

1. **Introduction (300 to 500 words):** State the research question clearly, explain why the topic matters and describe how you will investigate it. Do not open with a dictionary definition.
2. **Body (2,500 to 3,000 words):** Split it into two to four logical sections, each with its own subheading. Every section should move your argument or analysis forward instead of just summarizing information. Use evidence throughout and engage critically with your sources.
3. **Conclusion (300 to 500 words):** Bring in no new evidence. Summarize the findings, say plainly what your research has shown, and acknowledge limitations or areas for further study.
4. **Bibliography:** Use the citation format your subject requires (MLA, APA or Chicago). Every source cited in the text must be listed.

The 4,000-word figure is a ceiling, not a goal. Plenty of strong essays are 3,500 to 3,800 words. Once you pass 4,000, the examiner stops reading, so every sentence needs to earn its place.

## How Long It Takes

Schools usually plan the EE as about 40 hours of student work, though the real time students spend varies a lot. Those who begin early and work steadily find it far less stressful than those who squeeze it into the last few weeks.

A realistic timeline for students starting in Grade 11:

| Phase | When | What to Complete |
|---|---|---|
| Topic selection | End of Grade 11 (May/June) | Pick a subject, draft an initial research question, choose a supervisor |
| Research and reading | Summer before Grade 12 | Collect primary and secondary sources, keep organized notes |
| First draft | September to October (Grade 12) | Finish a full rough draft, meet your supervisor for the second reflection |
| Revision and editing | October to November (Grade 12) | Sharpen the argument, tighten the writing, check that citations are complete |
| Final submission | November to January (Grade 12, as set by your school) | Hold the final reflection session (the viva voce), write the reflective statement, hand in the essay and RPF |

Students who finish their research over the summer before Grade 12 report much lower stress in the fall, when IB coursework peaks and university application deadlines arrive at the same time.

## Mistakes That Cost Marks

Knowing which errors cost marks matters as much as following good practice. From our work with IB students at private schools across Canada and the United States, these come up most:

- **A research question that is too broad.** Broad questions produce shallow analysis. Keep narrowing until the question can truly be answered in 4,000 words.
- **Describing instead of analyzing.** Many students retell what their sources say instead of examining what the evidence means. Examiners reward analysis and a clear line of argument, not thorough summaries.
- **Treating the reflection as an afterthought.** The reflective statement on the RPF is marked under Criterion E. Brief notes after each supervisor session make it much easier to write well.
- **Leaving the bibliography until the end.** Keep a running bibliography from day one. Rebuilding sources at the end takes time and often leaves citations incomplete.
- **Choosing a topic to impress rather than to engage.** Students who write about what they find interesting produce more sophisticated analysis. Follow your curiosity, not whatever sounds most impressive.

## Closing Thoughts

The Extended Essay is one of the most intellectually rewarding challenges in the IB Diploma, and a real preview of the independent research students meet at university. Those who start with a specific question, a realistic timeline and steady effort usually produce work they are proud of.

## Frequently asked questions

### How long is the IB Extended Essay?

The maximum is 4,000 words, and examiners do not read past that point. Most strong essays land between 3,500 and 3,900 words. The count includes the introduction, body, conclusion and any quotations. The title page, contents page, references, bibliography and the reflection form are not counted, and footnotes that explain or discuss count toward the limit, so keep them for references.

### Can the Extended Essay be on any subject?

It is normally written in one of your six Diploma subjects, or in two of them if you choose the interdisciplinary pathway. You can also pick a subject you have some background in, but writing in a subject you study is strongly recommended. An HL subject you already take gives you an edge in depth of knowledge and quality of analysis.

### How does the Extended Essay grade count toward the Diploma?

The A to E grade is combined with your Theory of Knowledge grade in a matrix that can add up to three bonus points to your total IB score. An E on the essay means automatic Diploma failure whatever your other results, which makes it one of the highest-stakes components of the programme.

### When should students start the Extended Essay?

Most experienced IB coordinators suggest settling the research question and starting to collect sources by the end of Grade 11. Using the summer before Grade 12 for primary research and reading puts you in a much better position when the school year gets busy.

### How do I choose a supervisor?

Your supervisor must be a qualified member of staff at your school. You must have three formal reflection sessions with them, and the last is a short concluding interview called the viva voce. Choose someone with genuine interest in your topic who can give substantive feedback on your argument and methodology, because that relationship affects the quality of the final essay.
