WHY DO ASSESSMENT CENTERS WORK? THE PUZZLE OF ASSESSMENT CENTER VALIDITY

Abstract

The finding that assessment centers are successful in making valid predictions of managerial success is well established in the literature. Unfortunately, it is not clearly understood why assessment centers work. For example, construct validity of assessment center dimensions is rarely obtained. In this paper we affirm the evidence for predictive validity of assessment centers and conclude that assessment centers can work for a variety of purposes and in numerous contexts. But we also assert that we do not know why they work. The bulk of the paper goes on to raise possible explanations for the predictive validity observed in assessment centers and raises implications for practice and guidance of future research.
