Frequently asked questions
- How is the IB Internal Assessment graded?
- Each subject's IA is marked against its own set of criteria (typically 4–5 criteria, total 20–24 marks) defined in the official IB subject guide. The IA contributes 20–25% of your final subject grade.
- Which IB subjects does Criterion support?
- Criterion supports IAs across the major IB subjects, including Mathematics AA & AI, Physics, Chemistry, Biology, Economics, Business Management, ESS, Geography, History, English A, Language B, and Psychology.
- Can I get IA feedback before my teacher's draft deadline?
- Yes. Many IB students use Criterion on early drafts to identify weaknesses against the markscheme before submitting to their teacher.
- Will Criterion write my IA for me?
- No. Criterion only provides AI feedback and a predicted band. It will never write or paraphrase your Internal Assessment.
