What Is the IB Extended Essay?
The Extended Essay is a 4,000-word independent research project and one of the three core components of the IB Diploma (alongside Theory of Knowledge and Creativity, Activity, Service). It's mandatory for all Diploma candidates and can contribute up to 3 bonus points toward the final score when combined with the TOK grade — making it one of the highest-leverage assessments in the entire programme.
Students don't just answer exam questions or respond to prompts. They generate their own research question, conduct independent investigation over several months, and produce a mini-thesis that meets international academic standards. Students can write the EE in any IB subject — Mathematics, Physics, History, English Literature, Economics — or even interdisciplinary topics. They work under the guidance of a school-assigned supervisor, but the research, writing, and revision are entirely their responsibility.
The EE is graded A through E by external IB examiners using a detailed rubric that assesses Knowledge and Understanding, Application of analytical and evaluative skills, Research, Engagement (including use of sources and academic integrity), and Communication. This means the EE isn't just about getting facts right; it's about demonstrating how you think, how you interrogate evidence, and how you construct an argument.
For most students, the EE is overwhelming because it's the longest academic paper they've ever written, and they must manage the entire process independently. The timeline compounds the pressure: the EE typically spans six to nine months, but students often underestimate how much time each stage requires.
Yet this is precisely why the EE matters for university admissions. Universities understand that IB students who produce a strong Extended Essay have demonstrated genuine research capability, intellectual independence, and the ability to sustain complex thinking over time.
