What is a rubric generator?
A rubric generator is a free tool that turns a short assignment description into a structured grading table — criteria down the side, performance levels across the top, with clear descriptors in every cell. Instead of staring at a blank grid, you describe what you're grading, choose how many performance levels you want, and get a rubric you can paste straight into Google Docs, Sheets, or your school's LMS.
This free rubric generator works for essays, presentations, projects, group work, or any assignment where you need consistent, defensible grading criteria. Every cell gets a real descriptor — not just a score — so students know exactly what separates "Excellent" from "Needs Improvement."
Need rubrics for a whole term, aligned to standards, with weighting and auto-scoring built in? The AI Rubric Generator skill on KissMySkills turns Claude or ChatGPT into a dedicated rubric-building assistant that remembers your grading philosophy across every assignment.
