Abstract
This study develops and validates a theory-based measure of supervisory skills. Supervisors are the linking pin between the firm and its employees, and therefore play an important role for organizational performance and success. Clarifying performance standards, monitoring subordinate performance, and providing accurate performance evaluation enable effective supervision that is beneficial to the subordinate, and eventually organizational performance. I argue that rating discrimination, that is, the variation in the ratings a supervisor provides, reflects the extent to what a supervisor is able to fulfil her supervisory responsibilities effectively, or in short, her supervisory skills. By validating this measure in different contexts, I enable research and practice to use an easily comprehensible and measurable proxy for supervisory skills for research and personnel-decision purposes.
