What is the Extended Essay (EE)?

The Extended Essay is a 4,000-word independent research essay. It is a core requirement of the IB Diploma and must be completed over more than 11 months.

Key details

Aspect	Requirement
Length	4,000 words (max)
Format	Academic essay with research question
Subject	One of the student’s DP subjects (or approved interdisciplinary)
Timeline	Completed over 11+ months
Supervision	Supervised by a teacher (3–5 hours of support)

Choosing a research question

The research question drives the essay. It should be:

• Focused and researchable
• Appropriate to the subject
• Manageable within 4,000 words

Students often refine their question with their supervisor.

Assessment

The EE is marked against criteria (focus, knowledge, critical thinking, presentation, engagement). Total marks contribute to the core points (up to 3 points combined with TOK).

Common mistakes

• Too broad a question—hard to answer in 4,000 words
• Starting too late—research and drafting need time
• Poor referencing—academic integrity and citation matter
• Ignoring feedback—use supervisor guidance

Tips for success

1. Choose a topic you find interesting
2. Narrow the question early
3. Plan research and reading
4. Draft and redraft
5. Meet supervisors regularly
6. Check formatting and citations
