Theory of Knowledge (TOK)

Theory of Knowledge (TOK) is a core class in the IB Diploma Programme that encourages students to reflect on how we know what we know. It explores different ways of knowing (like reason, emotion, language, and sense perception) and how knowledge is built across various areas of knowledge (such as science, history, and the arts).

The course helps students develop critical thinking skills by questioning the reliability, origins, and limits of knowledge. It doesn’t teach specific content but focuses on understanding and evaluating knowledge itself.

TOK is assessed through a presentation (on a real-world knowledge question) and a 1,600-word essay based on a prescribed title.
