Frequently asked questions
- How is the IB Extended Essay graded?
- The Extended Essay is marked out of 34 across five criteria (A–E). The total maps to a letter grade A–E, contributing up to 3 bonus points toward the IB Diploma when combined with TOK.
- What is the EE word count limit?
- The Extended Essay has a maximum of 4,000 words. Examiners stop reading at 4,000 words, so going over costs you marks in Criterion D (Presentation).
- Can Criterion grade any subject's EE?
- Yes. Criterion supports Extended Essays across all major IB subjects, including the sciences, humanities, languages, and World Studies.
- Will Criterion write my Extended Essay for me?
- No. Criterion only provides AI feedback and a predicted grade. It will never write or paraphrase your EE — the work stays yours.
