Grading rubric prompt

A copy-and-paste prompt for ChatGPT, Claude or Gemini that gets a professional grading rubric on the first try, plus the cheapest model that does it well.

What most people type

make a rubric for grading a 5 paragraph persuasive essay

It works, but the AI has to guess your grade level, total points, e.g. 100 and standards, if any, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.

The better prompt

Create a grading rubric for a 5-paragraph persuasive essay.

Context: grade level [grade level], total points [total points, e.g. 100], and any state or school standards to align to [standards, if any].

Include:
- Criteria that professionals use for persuasive writing, such as thesis and claim, evidence and reasoning, counterargument and rebuttal, organization and structure (intro, three body paragraphs, conclusion), persuasive language and tone, and grammar, conventions and style. Add or drop criteria if [any criteria to emphasize] applies.
- 4 performance levels per criterion (for example Exemplary, Proficient, Developing, Beginning), each with a short, observable descriptor and a point value.
- A weight for each criterion, with the weights adding up to the total points.

Format: a markdown table with criteria as rows and performance levels as columns, followed by a line showing the total score and a short guide for converting scores to grades. Keep descriptors concise and written so students can understand them.

Replace the [brackets] with your details before you send it: grade level, total points, e.g. 100, standards, if any, any criteria to emphasize.
