(2) Objectivity
Objectivity is the measure of whether different evaluators (instructors) can reach the same result. For example, evaluation through multiple-choice questions is objective because the same result is obtained regardless of who marks the answers. On the other hand, rating of carefulness in a practical skill test has low objectivity because the result is likely to differ depending on the marker.
Objectivity greatly depends on the evaluation method. Therefore, examine the evaluation method with focus on how to enhance objectivity. When rating carefulness of working, you can enhance objectivity by defining the rating standard using a checklist of evaluation items.
