It is essential that rubrics are designed to measure what they should be evaluating (validity), but also that no matter who uses the rubric, the same score would be obtained (reliability). Validity and reliability ensure that students are evaluated consistently and fairly. Each instructor has a different discipline, but within the discipline it is important that the rubrics include the course outcome and components to be evaluated so that the evaluation can be fair and consistent no matter who might be assessing the performance, product, or process. In sum, rubrics must be consistent, valid, and reliable.
