Common questions

What IB assessment criteria are available here?

The criteria database covers the Extended Essay (EE), Theory of Knowledge (TOK) essay and exhibition, and Internal Assessment (IA) for multiple IB subjects across Groups 1 to 6.

Where do the criteria come from?

The criteria are stored locally in a structured database that mirrors the official IB descriptors. Descriptor wording is preserved as written, with no paraphrasing.

What is the AI grading prompt for?

Each criteria page includes an optional copyable prompt that embeds the official criteria and asks an AI to evaluate work criterion by criterion. It is a self-review tool — nothing is sent from this page.

How do I find my subject's IA criteria?

Select Internal Assessment, then choose your IB subject group and subject. The page filters the criteria database to the set that applies to your specific submission.
