Tom is a manager of a department with three work groups. He uses performance evaluation data to determine annual pay increases for the employees in his department. However, he has noted that one of the supervisors tend to give very high rates, another gives very low ratings, and the third rates everyone somewhere near the middle.

Which of the following evaluation procedures could Tom implement that would immune him from these rating errors?

A$.$ Forced choice

B$.$ weighted factor scale

C$.$ graphic rating scale

classification.
