This study presents the results of a predictive validity study of the Multijurisdictional Police Officer Examination (MPOE). The MPOE is a paper-and-pencil test of cognitive abilities developed to select entry level police officers. Criterion measures for the study included training performance, supervisory performance ratings and a file composite measure of negative work related incidents (e.g., use of force). There were 159 (120 majority and 39 minority group) members in the final validation sample. Results indicated that the MPOE was predictive of the three performance indices. Cumulation of results across seven studies (including the present effort) revealed a weighted average correlation between the MPOE and performance ratings of .20 (N=913). The potential generalizability of the results to other police departments is discussed.
