How should students be rated on a performance test?

Students should be rated on a performance test against a standard because this approach provides an objective and consistent basis for assessment. Evaluating performance against predetermined standards ensures that all students are measured according to the same criteria, which reflects their individual competency and skills relevant to the subject matter. This method promotes fairness and allows instructors to identify the strengths and weaknesses of each student, enabling them to provide targeted feedback and appropriate guidance for improvement.

Using standards for assessment also helps maintain the integrity of the evaluation process, making it easier to justify students' results and maintain quality in instruction. Unlike peer performance or curved grading, which may introduce variability based on class dynamics or overall cohort performance, assessing against a clear standard ensures that students are held accountable for their personal achievements and development. Additionally, random ratings lack any meaningful basis for evaluation, undermining the purpose of a performance test.
