To ensure rubric reliability, instructors should ask themselves the following questions as they are developing assessment rubrics and, if possible, test and re-test the rubric prior to implementation.
Are all scoring categories well defined?
Are all scoring categories connected to learning outcomes?
Are all scoring categories associated with clear criteria?
Are there clear differences between the criteria (i.e., expert, intermediate, novice)?
Would two different instructors using the rubric arrive at the same score when assessing student work?
