The extended essay (EE) is an in-depth study of a focused topic chosen from a list of approved Diploma Program subjects — normally one of the student's six chosen subjects for the IB Diploma. It provides students with an opportunity to engage in personal research in a topic of their own choice, under the guidance of a supervisor (a teacher in the school). This leads to a major piece of formally presented, structured writing, in which ideas and findings are communicated in a reasoned and coherent manner, appropriate to the subject chosen.

The extended essay is:
  • compulsory for all Diploma Program students  
  • externally assessed and, in combination with the grade for theory of knowledge, contributes up to three points to the total score for the IB Diploma
  • a piece of independent research/investigation on a topic chosen by the student in cooperation with a supervisor in the school
  • chosen from the list of approved Diploma Program subjects, published in the extended essay guide (see list below)
  • presented as a formal piece of scholarship containing no more than 4,000 words
  • the result of approximately 40 hours of work by the student
  • concluded with a short interview, or viva voce, with the supervising teacher (recommended)
In the Diploma Program, the extended essay is the prime example of a piece of work where the student has the opportunity to show knowledge, understanding and enthusiasm about a topic of his or her choice. In those countries where it is the norm for interviews to be required prior to acceptance for employment or for a place at university, the extended essay has often proved to be a valuable stimulus for discussion.
