  • 3–4

    An appropriate question for investigation has been stated.

Evidence from sources is included, but is not integrated into the analysis/argument.

  • 7–9

    The investigation is generally clear and well organized, but there is some repetition or lack of clarity in places. The response moves beyond description to include some analysis or critical commentary, but this is not sustained. There is an attempt to integrate evidence from sources with the analysis/argument.

Optional: AI grading prompt

For self-review only

A copyable prompt that embeds the criteria above and asks an AI to grade the work criterion by criterion. Use it as a draft sanity check — not a substitute for teacher or examiner feedback.

Common questions

Where do the criteria come from?

The criteria are stored locally in a structured database that mirrors the official IB descriptors. The page only displays them — descriptor wording is preserved as written, with no paraphrasing.

Why pick subject, level, and component?

The criteria differ by assessment type, subject, level, and component. The selectors at the top filter the database to the criteria set that applies to your specific submission.

What is the AI grading prompt at the bottom for?

It is an optional helper. The prompt embeds the same criteria you see above and asks an AI to evaluate the work criterion by criterion. Useful for a quick self-review before teacher feedback.

Is my work sent anywhere?

No. The page only loads criteria. If you choose to use the AI prompt, you copy it manually and paste it into the AI tool of your choice — nothing leaves this page.
