# How to Write a Strong IB Extended Essay: A Grade 11 and 12 Plan

**The short answer:** To write a strong IB Extended Essay, choose a narrow, arguable question in a subject you study, settle your topic in the second half of Grade 11, and plan about 40 hours of work spread over nine to twelve months. The most marks go to discussion and evaluation, worth 8 of 30 points.

For many IB Diploma students, the Extended Essay (EE) is the scariest part of the programme. At 4,000 words, it is the longest piece of independent academic writing most students in Grades 11 and 12 have tried. Students at schools like Upper Canada College, Havergal, Branksome Hall and other IB World Schools commonly know the EE is coming but have no idea where to begin.

This guide covers each stage of the process, from picking a subject and narrowing the research question to organizing your argument and meeting the IB's assessment criteria. If you are about to start Grade 11, or you are already well into your research, you will find concrete steps below.

## What the IB Extended Essay Involves

The EE is a 4,000-word independent research paper that every IB Diploma student has to complete. It is graded from A to E. Together with your Theory of Knowledge grade, it can add up to 3 points to your Diploma total of 45. An E in the EE automatically fails the Diploma, so the essay is an opportunity that also carries real stakes.

It is written in a subject from the IB's approved list and needs a focused research question, a sustained argument or analysis, and a formal bibliography. You meet with a supervisor from your school along the way, including three formal reflection sessions. Your final submission also includes a Reflection and Progress Form (RPF), which holds a 500-word reflective statement about what you learned from the process.

Despite its size, the EE is manageable for students who plan well. Those who begin early, choose a focused topic and write in drafts regularly earn strong grades.

## Choosing a Topic

The best EE topics are specific, arguable and meaningful to you. A broad question such as “What caused World War I?” is far too wide for 4,000 words. A better one might be: “To what extent did the war guilt clause of the Treaty of Versailles contribute to the rise of National Socialism in the Weimar Republic?” It is narrow enough to answer with real evidence, yet wide enough to carry an argument.

A practical way to choose:

1. **Pick a subject you enjoy.** You will put about 40 hours into this question over many months, so choose something that really interests you, ideally a subject you already take at HL.
2. **Find a live debate or a gap.** The best essays argue a position or analyze a problem instead of simply describing. Look for a question where reasonable people could disagree based on the evidence.
3. **Check your sources early.** Before committing, make sure you can get the primary or secondary materials your argument will depend on.
4. **Test it with your supervisor.** A good supervisor can tell you within one meeting whether the scope suits 4,000 words.

Experienced IB educators say the single most frequent EE mistake is a topic that is too broad. A tightly scoped question almost always produces a better paper than an ambitious but vague one.

## How Long the Extended Essay Takes

Schools usually plan the EE as about 40 hours of student work, and many students spend a little more, spread across nine to twelve months. What matters is spreading the hours over the second half of Grade 11 and the start of Grade 12 instead of cramming them into a few weeks.

A realistic timeline:

| Stage | When | Time Required |
|---|---|---|
| Choose a subject and first topic idea | January to February, Grade 11 | 2 to 3 hours |
| Narrow the research question, first reflection session | March to April, Grade 11 | 3 to 4 hours |
| Background reading and primary research | May to August | 9 to 11 hours |
| First full draft | September to October, Grade 12 | 9 to 11 hours |
| Supervisor feedback, revision, second reflection session | October to November, Grade 12 | 5 to 6 hours |
| Final draft, viva voce, reflective statement, submission | November to January, Grade 12 (set by your school) | 6 to 8 hours |

Students who leave the EE until Grade 12 report more stress and lower grades. Starting in the second half of Grade 11 gives you the time and headspace to write a really good paper.

## What Examiners Look For

Examiners mark the EE on five criteria worth 30 points in total:

- **A: Framework for the Essay (6 points):** Do the research question, methods and structural conventions (title page, contents, referencing, word count) give the essay an effective framework?
- **B: Knowledge and Understanding (6 points):** Does the student show real understanding of the topic and the concepts of the subject?
- **C: Analysis and Line of Argument (6 points):** Does the student analyze the information and build a clear line of argument?
- **D: Discussion and Evaluation (8 points):** Does the student discuss the findings in a balanced way and evaluate the essay?
- **E: Reflection (4 points):** Does the reflective statement show how the experience affected the student as a learner?

Discussion and evaluation carries the most weight, 8 of the 30 points, and analysis and line of argument adds 6 more. From our work with students at leading IB Diploma schools, the essays that earn an A or B all do one thing well: they argue. They do not stop at describing or summarizing. They analyze, evaluate and defend a clearly stated position through the full 4,000 words.

## Structuring the Essay

A strong EE has a clear structure that examiners find easy to follow:

- **Introduction (300 to 400 words):** State the research question, give brief context and outline your method and scope. Avoid claims you have not yet supported.
- **Body (2,800 to 3,200 words):** Build the argument in clearly labelled sections. Use evidence, cite sources and analyze rather than summarize. Each section should push the central argument forward.
- **Conclusion (300 to 400 words):** Return to your research question, summarize the findings and be honest about the limits of your research. Leave out new ideas and new evidence.
- **Bibliography:** List every source in one consistent citation style (MLA, APA or Chicago, depending on the subject).
- **Reflection and Progress Form (RPF):** Attend all three reflection sessions, the last being the viva voce, then write your 500-word reflective statement. It feeds directly into Criterion E.

Track your word count as you go. Examiners do not read anything past the 4,000-word limit, and students who run long often lose their conclusion entirely.

## Frequently asked questions

### Which subjects can the Extended Essay be written in?

Any subject on the IB's list for your exam session, normally one of your own six. Most students use a subject they take at HL, although SL subjects are allowed. The interdisciplinary pathway, which replaced World Studies, lets you bring the lenses of two Diploma subjects to one question.

### Can I write the Extended Essay in a subject I do not study at school?

Technically yes, but it is uncommon and risky. Without a natural supervisor or formal instruction in the subject, you start at a disadvantage. Talk to your IB coordinator before going down that road.

### How does the Extended Essay affect my Diploma score?

Your EE grade and your Theory of Knowledge grade are combined through an IB matrix to give 0 to 3 of the 45 points on the Diploma scale. An A in both earns 3 points. An E in either one automatically fails the full Diploma, whatever your subject scores are.

### How many supervisor meetings do I need?

The IB requires three formal reflection sessions with your supervisor, and the last is the viva voce, a short concluding interview of 10 to 15 minutes. Many students also meet their supervisor informally more often, and substantive feedback along the way usually produces a stronger paper.

### What is the most common Extended Essay mistake?

Choosing a topic too broad to argue in 4,000 words. The runner-up is summarizing sources instead of analyzing them. Both cost marks on Criteria C and D (analysis and line of argument, and discussion and evaluation), which together carry 14 of the 30 marks. A focused question and an argumentative structure are the two changes that most reliably lift an EE grade.
