A rubric is a scoring tool that lists criteria for evaluating a piece of work or performance. It describes levels of quality from excellent to poor for each criterion. Rubrics help define quality, improve student performance, and reduce teacher evaluation time. When designing a rubric, the creator identifies observable attributes for the task and describes characteristics for each attribute and quality level. Sample rubrics evaluate oral interviews on criteria such as speech clarity, question preparation, knowledge, historical accuracy, character, and posture.
