Score Descriptors for each Criterion:
Printable: Full Rubric for all subjects
- Examiners will mark your EE using the "best-fit" model - you will be credited for what is in your essay, instead of being penalized for what is missing.
- The best-fit approach means that it is not necessary for every indicator of a grade descriptor to be met for that mark band to be awarded.
A – Excellent 27 to 34
B – Good 21 to 26
C – Satisfactory 14 to 20
D – Mediocre 7 to 13
E – Elementary 0 to 6
Please note that the 'official' boundaries are not published by the IB until after each exam session.
