IB marking, criterion by criterion — a first pass you confirm
Mark was built on criterion-referenced rubrics from day one. Upload your students' IB essays or IAs with the criteria, and Mark scores each criterion with quoted evidence, ready for you to review and confirm.

- Built for IB-style criterion marking, not a grammar checker with a grade.
- A score per criterion with the exact lines as evidence.
- You stay the marker of record — Mark does the first read.
I do the first read, not the final call. You confirm or change every mark I give — I just make sure the whole class is read against your rubric the same way, with the evidence for every score right there.
