An AI grader that follows your rubric, not its own.
Can AI grade with my own rubric?
Short answer: Yes. You upload the rubric or answer key you already use, check that it has been read correctly, and the AI drafts each score against those criteria with a short justification. Uncertain scores are flagged, and you approve or change every grade before it reaches students.
How it works
From your test to reviewed results.
- 1Start from the rubric you already haveUpload the rubric, answer key or mark scheme alongside the test. You confirm it before any student work is graded, with uncertain rows shown first.
- Points-based answer keys and criteria rubrics.
- Edit a row if it was read wrongly.
- The same rubric applies across the whole class set.
- 2Every score tied to a criterionA score you can’t explain to a student or parent isn’t much use. Each drafted score points back to the part of your rubric it rests on.
- Short justification for each score.
- Feedback written for the student.
- Partial credit where your rubric gives it.
- 3Consistent across the class, and still yoursApplying one rubric to every script keeps grading consistent from the first test to the last. You review the flagged answers, adjust anything you disagree with, and release.
- Flagged answers first.
- Change any score or comment.
- Export grades and student PDFs.
Example answer
One answer, marked against your scheme.
Each answer is checked point by point against the mark scheme you uploaded, not a generic rubric.
Switch between the AI draft and the answer after your review. Example data.
Q4 · Science · Rates of reaction · 3 marksExample data
Explain why increasing the temperature increases the rate of a reaction.
Student answerthe particles move faster so they collide more often
Mark scheme · Points
✓Particles have more kinetic energy or move faster.
✓More frequent collisions. Allow “collide more often”.
–More collisions have at least the activation energy. Not in this answer.
×Do not accept: “particles collide harder” on its own.
Marker 1: 2Marker 2: 2Markers agree
Both markers credited the same two points, so the mark stands.2/3
