TOK/EE Matrix

Extended Essay and Theory of Knowledge Assessment

What is Extended Essay (EE)?

The extended essay of approximately 4,000 words offers the opportunity for IB students to investigate a topic of special interest, usually one of the student’s six Diploma Programme subjects, and acquaints them with the independent research and writing skills expected at university. It is intended to promote high-level research and writing skills, intellectual discovery and creativity—resulting in approximately 40 hours of work. It provides students with an opportunity to engage in personal research on a topic of choice, under the guidance of a supervisor. © International Baccalaureate Organization 2010

What is Theory of Knowledge (TOK)?

The interdisciplinary theory of knowledge course is designed to develop a coherent approach to learning that transcends and unifies the academic areas and encourages appreciation of other cultural perspectives.

The theory of knowledge course is in part intended to encourage students to reflect on the huge cultural shifts worldwide around the digital revolution and the information economy. The extent and impact of the changes vary greatly in different parts of the world, but everywhere their implications for knowledge are profound. Theory of knowledge encourages critical thinking about knowledge itself and aims to help young people make sense of what they encounter. Its core content focuses on questions such as the following.

  • What counts as knowledge?
  • How does it grow?
  • What are its limits?
  • Who owns knowledge?
  • What is the value of knowledge?
  • What are the implications of having, or not having, knowledge

The Diploma Points Matrix

If a student gains an “E” in either component 28 points overall will be required to pass the IB Diploma (not 24 points as is usual). A grade “A” in one of the components earns an extra point even if the other is a grade “E”. An “E” grade in both the Extended Essay and Theory of Knowledge means an automatic failure of the IB Diploma.
