Theory of Knowledge is one of the three required core elements in the IB Diploma Programme and a required course for all full IB Diploma Students.
TOK is a course about critical thinking and inquiring into the process of knowing, rather than about learning a specific body of knowledge. The TOK course examines how we know what we claim to know. What is knowledge, and how do we get it? What is truth, and how do we recognize it? Is my truth also your truth? The course tries to answer these questions by encouraging students to analyse what they (think they) know and to explore how to test these assumptions with real life situations, both their own and those they learn about.
