Effects of Disaggregation on Managerial Assessment Center Validity

Assessment center validity data from a large, international petrochemical company were disaggregated by managerial level and business stream. As with previous research, the correlations were higher for the current job grade criterion than for performance ratings. Overall, disaggregating the data did not have the effect of increasing the assessment center—performance rating validities. However, when the validation data were disaggregated by business stream, there were differences in the pattern of the relationships between assessment factors and performance.
