The Extended Essay is a unique opportunity for students to engage in independent research. As part of the diploma each student chooses a topic that interests them and undertakes an in-depth 4000-word study.
The scholarly apparatus that the essay demands – including citations, bibliography, abstract – is a very effective preparation for university dissertations, projects and theses. It is a distinctive feature of the IB Diploma, and universities regularly comment positively on the scope, depth and structure of argument that the Extended Essay inspires.
