Theory of knowledge
Theory of knowledge (TOK) is assessed through an oral presentation and a 1,600 word essay.
It asks students to reflect on the nature of knowledge, and on how we know what we claim to know.
TOK is part of the International Baccalaureate® (IB) Diploma Programme (DP) core, and is mandatory for all students.
Learn more about TOK in a DP workshop for teachers.
