Extended essay (EE)

The extended essay is an independent, self-directed piece of research, finishing with a 4,000-word paper.

One component of the International Baccalaureate® (IB) Diploma Programme (DP) core, the extended essay is mandatory for all students.

The extended essay provides:

  • practical preparation for undergraduate research
  • an opportunity for students to investigate a topic of personal interest to them, which relates to one of the student's six DP subjects, or takes the interdisciplinary approach of a World Studies extended essay.

Through the research process for the extended essay, students develop skills in:

  • formulating an appropriate research question
  • engaging in a personal exploration of the topic
  • communicating ideas
  • developing an argument. 

Participation in this process develops the capacity to analyze, synthesize and evaluate knowledge.

An extended essay can also be undertaken in world studies, where students carry out an in-depth interdisciplinary study of an issue of contemporary global significance, across two IB diploma disciplines.

Students are supported throughout the process of researching and writing the extended essay, with advice and guidance from a supervisor who is usually a teacher at the school.

Students are required to have three mandatory reflection sessions with their supervisors. The final session, a concluding interview, is also known as viva voce.

The extended essay and reflection sessions can be a valuable stimulus for discussion in countries where interviews are required prior to acceptance for employment or for a place at university.

All extended essays are externally assessed by examiners appointed by the IB. They are marked on a scale from 0 to 34.

The score a student receives relates to a band. The bands are:

  • A – work of an excellent standard.
  • B – work of a good standard.
  • C –work of a satisfactory standard.
  • D – work of a mediocre standard.
  • E – work of an elementary standard.
