A rubric is a scoring guide used to evaluate work. It breaks an assignment into criteria, such as accuracy, organization, evidence, creativity, grammar, or presentation, and explains what different performance levels look like.
Why rubrics help
Rubrics make expectations clearer for students and grading more consistent for teachers. A student can use a rubric before submitting work to understand what needs improvement.
Rubrics and feedback
A rubric can support formative assessment when used during the learning process, or summative assessment when used to grade final work.
The best rubrics are specific enough to guide improvement, not just assign a score.
