- Up to 4,000 wordsKeep the whole argument inside the limit. A narrow research question makes that much easier.
- A separate reflection statementFrom 2027 you submit one RPF reflective statement of up to 500 words. Criterion E is marked from it.
- Marked by an IB examinerYour supervisor doesn't mark the EE. An IB examiner does, using the same criteria for every subject.
