The extended essay is an in-depth study of a focused topic chosen from the list of approved Diploma Programme Subjects – normally one of the student’s six chosen subjects for the IB Diploma. It is intended to promote high-level research and writing skills, intellectual discovery, and creativity, all of which are highly beneficial to university students regardless of career/degree plans.
