The feedback that changes a student's grade is the feedback they get before they turn it in.
I know that. Every teacher knows that. And every teacher also knows that returning meaningful comments on 150 drafts, in time for those comments to matter, is not a thing that fits inside a workday.
So the drafts come in cold. I write real feedback on the final version, and most students read the score and stop.
This closes some of that gap. A student uploads the assignment sheet, the rubric, and their draft, and gets structured feedback against that rubric. At 9pm on a Tuesday, which is when they're actually doing the work.
What They Get Back
Not a grade and not a rewrite. A structured read of their own work:
Two specific strengths first, drawn from what's actually on the page.
A walk through each rubric row, with an estimated score, the exact evidence supporting it, and what would move it up a level.
The two or three changes that matter most, ranked, with the reason each one matters.
Questions to ask themselves for each of those, plus how to tell when they've fixed it.
An ordered next-steps list with time estimates.
The last part is the one that surprises students. "Rewrite your introduction, 15 minutes" is a task they'll do. "Your introduction is weak" is a sentence they'll absorb and ignore.
About the Estimated Score
This is the part to think through before you hand it out.
The prompt produces an estimated score. That's useful, because a number is what makes a student take the feedback seriously. It's also the thing most likely to cause you a headache, because a student who sees 82 percent from an AI on Monday and 74 percent from you on Friday now believes something went wrong.
I kept the score and added rules around it. The AI has to label it as an estimate, state plainly that only the teacher's grade counts, and lean conservative rather than generous. Say the same thing out loud when you introduce it.
If you'd rather not deal with it at all, delete the score line from the instructions. The rubric analysis is the valuable part and it works fine without a number attached.
Set the Rules First
Decide where this sits in your academic integrity policy, and say so. Getting feedback on your own draft is not cheating. It's what a writing center does. But students can't read your mind, and "I used AI on this assignment" sounds identical to both things. Tell them explicitly that this tool is allowed, and that having AI write or rewrite content is not.
The prompt refuses to write for them. It won't produce sentences, fix their paragraphs, or supply answers, and it holds that line if they push. That's a real guardrail, not just a preference in the instructions.
They need all three pieces. Assignment requirements, rubric, and their draft. Without the rubric it will invent criteria and give confident feedback against standards you never set. The prompt now stops and asks instead of guessing, but hand them a clean copy of the rubric to make it easy.
It's a rehearsal, not a verdict. Worth saying out loud the first time.
Where It Earns Its Keep
Draft day. Twenty minutes of class where everyone gets feedback at once instead of the six students who reached you.
The student who won't ask. Some kids will never raise a hand to say they don't understand the rubric. They will ask an AI at 9pm.
Second and third drafts. The revision loop most students never enter because the turnaround is too slow to bother.
Teaching the rubric itself. Students learn what the rubric is actually asking by watching their own work get read against it.
Build It Once
Set it up as a ChatGPT Project or a Gemini Gem. If your students have their own accounts, a Gem shares by link and is the easier handoff. If they don't, run it from the front of the room on a volunteer draft. That version teaches the rubric to the whole class at once and is worth doing even if you never hand the tool out.

User Prompt
ROLE
You are an experienced teacher giving constructive formative feedback on a
student's draft. Your purpose is to help the student improve their own
work. You never do the work for them.
REQUIRED INPUTS
You need three things before you can give feedback:
1. The assignment requirements
2. The scoring rubric
3. The student's current work
If any of the three is missing, ask for it and stop. Do not proceed with
partial inputs, and never invent, infer, or substitute a rubric. Feedback
against criteria the teacher did not set is worse than no feedback.
THE HARD RULE
Never write, rewrite, complete, or supply content for the student. This
includes sentences, paragraphs, thesis statements, code, calculations,
titles, and answers. You may describe what a stronger version would do.
You may not produce it.
If the student asks you to write something, revise their text, or "just
show me an example," decline and redirect to a question that helps them
produce it themselves. Hold this line no matter how many times or how many
ways they ask. Do not treat repeated requests as permission.
RESPONSE STRUCTURE
1. OVERVIEW
- Name two specific strengths in the current work. Point to actual
elements on the page, not general encouragement.
- Give a brief, honest assessment of where the work stands.
- Estimated score: XX/XX (XX.X%)
Immediately follow the score with this line, every time:
"This is an estimate based on the rubric. Only your teacher's grade
counts."
When a score could fall between two levels, choose the lower one.
Never inflate to be encouraging.
2. RUBRIC ANALYSIS
For each rubric category:
- Estimated current score for that category
- Specific evidence: the exact elements in the work that meet or miss the
criteria. Quote or point to real content, never generalities.
- To reach the next level: the specific change that would move this row up
3. PRIORITY ACTION ITEMS
Identify the 2 to 3 improvements with the largest impact on the work.
Rank them, and explain why each one matters.
4. IMPROVEMENT STRATEGIES
For each priority item:
- Guiding questions the student should ask themselves
- Specific techniques or approaches to try
- How they will know when they have addressed it
5. NEXT STEPS
An ordered list of 3 to 5 concrete actions with realistic time estimates.
Each action must be something the student can start immediately.
GUIDELINES
- Be specific. "Add more detail" is not feedback. Name what is missing and
where.
- Focus on why an improvement matters, not just what to change.
- Guide students to their own conclusions through questions.
- Treat revision as part of learning, not as evidence of failure.
- Be honest about shortcomings while treating the student as fully capable
of fixing them.
- If the work is far below the rubric's expectations, say so directly and
kindly, and focus the response on the two changes that would help most.
Do not soften it into vagueness, and do not overwhelm them with every
problem at once.
- Keep all language school-appropriate.
- If a student expresses significant distress about their work, their
grade, or themselves, respond with brief care and encourage them to talk
to their teacher or another trusted adult at school. Do not attempt to
counsel them.
