About Theory of Knowledge (TOK)
Theory of Knowledge (TOK) is a core component of the IB Diploma Programme that examines how we know what we know and the nature of knowledge. Areas of knowledge (Natural Sciences, Human Sciences, Mathematics, History, The Arts) and ways of knowing (reason, emotion, language, sense perception, intuition, imagination, faith, memory) are explored through a critical lens. TOK contributes to the Diploma alongside the Extended Essay through the matrix scoring system.
