Theory of Knowledge
TOK explores the nature of knowledge and how we know what we claim to know. Students critically reflect on areas of knowledge and ways of knowing.
The central question
“How do we know what we claim to know?”
One core theme, two optional themes, five areas of knowledge
TOK runs alongside the six subjects for both years of the diploma, with at least 100 teaching hours. One part of the assessment is marked in school and the other by IB examiners.
