Ethnic and gender subgroup differences in assessment center ratings: A meta-analysis.

Abstract
Assessment centers are widely believed to have relatively small standardized subgroup differences (d). However, no meta-analytic review to date has examined ds for assessment centers. The authors conducted a meta-analysis of available data and found an overall Black-White d of 0.52, an overall Hispanic-White d of 0.28, and an overall male-female d of -0.19. Consistent with our expectations, results suggest that Black-White ds in assessment center data may be larger than was previously thought. Hispanic-White comparisons were smaller than were Black-White comparisons. Females, on average, scored higher than did males in assessment centers. As such, assessment centers may be associated with more adverse impact against Blacks than is portrayed in the literature, but the predictor may have less adverse impact and be more "diversity friendly" for Hispanics and females.
