Build a Grading Rubric for an Assignment
Generate a complete percentage-weighted rubric with four performance levels for any assignment.
This prompt generates a percentage-weighted grading rubric with four named performance levels and explicit point ranges, formatted as a table totaling 100 points. Use it when you need a defensible, transparent rubric you can hand to students before they start. The four-level descriptors (Excellent through Beginning) are what make grading consistent and appealable — they replace 'this feels like a B' with criteria a student and a second grader would both read the same way.
You are a curriculum designer. Create a detailed grading rubric for a [ASSIGNMENT TYPE: e.g. research paper, presentation, lab report] for [GRADE LEVEL / COURSE]. Include 4-5 evaluation criteria. For each criterion: (1) weight as % of total grade, (2) performance descriptors for 4 levels (Excellent/Proficient/Developing/Beginning), (3) point range for each level. Format as a table. Total points: 100.

Illustrative example — your results will vary by tool and inputs.
Get sharper results
- 01Name your specific learning objectives so the criteria assess what you actually taught rather than generic essay traits.
- 02Ask it to write descriptors in second-person student-facing language ('You state a clear claim...') so the rubric doubles as an instruction sheet.
- 03Check that the weights reflect what you'll really emphasize — it's easy to let mechanics creep up to 25% when the lesson was about argument.
- 04Request that point ranges within a level never overlap and the band tops sum cleanly to 100, then verify the math yourself before distributing.
- 05Have it add a short 'common pitfalls' note per criterion so students see what drops them a level before they submit.
Adapt it for your case
Ask for a single-point format with only the proficient column defined and blank space for what exceeded or fell short.
Add a collaboration criterion and a self/peer-assessment column to separate individual contribution from the shared product.
Provide the standards codes you teach to and ask it to tag each criterion with the standard it measures.
Common questions
Can I use a different number of performance levels?
Yes — ask for three or five levels instead of four; just keep the point ranges contiguous and summing to your total.
Will students actually understand the descriptors?
They will if you request student-facing language; the default can be teacher-jargony, so ask it to rewrite at the reading level of your grade.
How do I adapt this for a different assignment fast?
Keep the structure and re-run with a new assignment type and a note on what changes; the criteria will shift while the four-level scaffold stays consistent.
