This document provides guidance on designing effective rubrics for assessing student performance. It defines what a rubric is and compares rubrics to checklists. Rubrics can be holistic, assessing the overall quality of work, or analytic, assessing various criteria separately. The document recommends determining clear criteria and descriptors, involving students, limiting criteria to key aspects, using concrete language and examples, and pilot testing rubrics. Rubrics should be task-specific and altered based on experience to improve clarity and usefulness for students.
