The Theory of Knowledge (TOK) course is a core requirement of the IB Diploma Programme designed to help students critically explore knowledge itself—how we know what we claim to know—and examine perspectives from various disciplines and cultures. TOK is at the heart of the IB’s mission to develop inquiring, knowledgeable, and reflective learners.
What Are the IB TOK Assessment Components?
TOK is assessed through two key components that must both be completed for the IB Diploma:
1️⃣ TOK Essay
- Length: Maximum 1,600 words (excluding references, diagrams, tables, and footnotes).
- Task: Choose one of six prescribed titles (issued by the IB each session) and write an essay exploring a central knowledge question.
- Content:
- Examine at least two Areas of Knowledge (AOKs), such as history, natural sciences, or the arts.
- Discuss Ways of Knowing (WOKs), like reason, emotion, or perception.
- Analyze knowledge claims and counterclaims using real-life examples.
- Assessment: Externally marked by IB examiners.
- Preparation: Typically involves about 10 hours of guided instruction plus independent planning and drafting.
2️⃣ TOK Exhibition
- Task: Create an exhibition of three objects linked to one of 35 prescribed TOK prompts (e.g., “What counts as good evidence for a claim?”).
- Purpose: Apply TOK concepts to the real world, demonstrating personal engagement with knowledge issues.
- Assessment: Internally marked by your teacher, externally moderated by the IB.
Why Is TOK Important?
- Core requirement: Both the essay and exhibition are mandatory. Failing TOK (grade E) means you cannot earn the full IB Diploma.
- Bonus points: TOK, combined with the Extended Essay (EE), contributes up to 3 additional core points toward your diploma.
- Skill development: TOK helps you:
- Critically evaluate knowledge claims.
- Understand cultural and personal biases.
- Strengthen analytical, argumentative, and reflective skills.
- Apply knowledge concepts to real-world contexts.
TOK Submission and Assessment Details
- Both components must meet IB deadlines set by your school.
- Teachers can guide you in structuring and refining your work but cannot edit or mark the final essay.
- TOK is studied over two years alongside your other IB subjects.
