When to use this

You’re 11 essays into a stack of 32 and your comments are getting lazy. The rubric scores still come out the same, but the personalized feedback turns into “good evidence!” or “work on transitions” — language that doesn’t help the kid revise.

This prompt holds you to your own rubric, forces specific quotes from the student’s writing, and caps total words so feedback stays surgical instead of sprawling.

When NOT to use this

Don’t use this without your real rubric pasted in. Generic AI rubric scoring is the dishonest version of grading — it gives a score with no defensibility when a parent asks why.

For first-draft formative feedback where you’d give a check-plus by hand, this is overkill. Save it for graded work or for revisions where the kid needs to see exactly what to fix.

Authoring notes

  • The “do not invent your own criteria” line is the most important sentence in the prompt. Without it, AI will quietly upgrade your 4-criterion rubric to its own 7-criterion one.
  • The 250-word cap matters: longer comments are not better feedback, they’re easier-to-ignore feedback.
  • Always read the AI output before sending. It will occasionally hallucinate a quote that sounds like the student but isn’t. Catching that is your job.

Example output

RUBRIC SCORES
- Thesis: 3/5 — "I think Romeo was tragic" (sentence 4) is implied but never stated as the central claim. The thesis is doing real work in paragraph 2, not paragraph 1.
- Evidence: 4/5 — Three quotes, all cited correctly. The Mercutio quote in paragraph 3 is doing the most work.
