A rubric is an assessment tool that describes levels of achievement or proficiency in a specific area using a matrix format. It provides a common framework and language for evaluation. Well-trained evaluators can assess complex work consistently using rubrics, which describe criteria at different proficiency levels rather than comparing students. Rubrics promote shared grading standards among faculty and substantive discussion when developed collaboratively. An effective rubric includes a task description, criteria to be evaluated arranged in rows, proficiency levels in columns, and descriptions of each criterion at each proficiency level.
