Theory of Knowledge (TOK) is an interdisciplinary course designed to help students question and understand how they know what they know. Students study how individuals from various disciplines view the world in order to develop their own ways of thinking. By stimulating analysis of knowledge across disciplines, TOK seeks to help students make sense of school and the world. 

At Central TOK is taken by all full IB Diploma and Scholar with Distinction students in 11th and 12th grade. In addition to exploring questions about knowledge, the course provides space for students to do most of their work on the IB Extended Essay, working through a series of guided activities designed to help them learn the process of writing a college level research paper. It also serves as a support class for IB DP cohort students,helping them develop the organizational and self-managements skills needed to succeed in a challenging academic program.
