Find out if your object justifications make convincing links to the IA prompt and to TOK concepts. A free preview is included; the full report is $4.99.
IB TOK Exhibition rubric: how it is marked (holistic, out of 10)
Since the 2022 syllabus the TOK exhibition is marked holistically against a single global-impression instrument, out of 10, with no sub-criteria. The examiner works from one guiding question — "Does the exhibition successfully show how TOK manifests in the world around us?" — and places your commentary in one of five bands: Excellent (9–10), Good (7–8), Satisfactory (5–6), Basic (3–4), Rudimentary (1–2).
Your exhibition must present exactly three objects with a commentary of about 950 words in total. The number of objects caps your possible mark: with only two objects the maximum is 6, and with a single object the maximum is 3.
A high-scoring exhibition therefore does three things well, and IBLens checks each:
- Specific, real objects tied to the prompt: Each object is concrete and particular (not a generic or symbolic stand-in), and its link to the exact wording of the chosen IA prompt is made explicit.
- Genuine TOK content: Each object is used to explore how knowledge works — not merely named — with enough depth to illuminate the prompt.
- A coherent, justified whole: The commentary argues rather than asserts, and the three objects work together to answer the prompt.
Common TOK Exhibition mistakes IBLens catches
- Generic or symbolic objects: Choosing abstract symbols ("a book representing knowledge") rather than specific, real-world objects with a concrete epistemic connection to the prompt.
- Naming TOK concepts without engaging with them: Asserting that an object "connects to knowledge" without explaining how the object actually shows knowledge being produced, shared or valued in the world.
- Objects that do not work together: Three disconnected objects that each make separate points, rather than building a coherent, cumulative argument about knowledge in the context of the prompt.
- Weak justification length: Each object commentary should be roughly 100 words of substantive argument. Brief, superficial justifications score in the lowest mark band.
- Ignoring the IA prompt wording: Your justification must address the specific language of the chosen IA prompt — not just the general topic of knowledge.
Frequently asked questions
- How is the TOK Exhibition different from the TOK Essay?
- The TOK Exhibition involves choosing three real-world objects and writing a short commentary (roughly 950 words total) explaining how each object connects to one of the 35 IA prompts. The TOK Essay is a 1,600-word essay on a prescribed title.
- What is the word limit for the TOK Exhibition?
- The IB recommends approximately 950 words total across all three object commentaries, with no strict per-object limit.
- Is the TOK Exhibition grader free?
- Every essay gets a free preview (band range, weakest criterion with full feedback, top risks). The full report — exact score and every criterion with comments — unlocks for $4.99, or $19.99 for a pack of five.
