Theory of knowledge (TOK), a unique study of epistemology in the IB Diploma Programme, opens up a wide window of reflection on the nature of the knowledge you have constructed as a knower and the process of knowing. You get to critically reflect on the reliability of information treated as knowledge through the twelve TOK concepts. The three interconnected TOK parts core, the optional themes, and the areas of knowledge (AOKs)- are explored through the open, generic, and contestable knowledge questions, which are organized in a knowledge framework having four elements as key players in exploring, comparing, and connecting the AOKs and optional themes.

The new TOK curriculum, TOK 2022 has the externally assessed task, the TOK essay worth 67%, and the internally assessed new task, the TOK exhibition worth 33% of the grades. While the TOK essay connects the prescribed title to the relevant AOKs, the TOK exhibition explores how TOK manifests in the real world through specific real-life objects of personal importance with an IA prompt within one of the TOK themes.
