A replication of an original study of managerial assessment centers performed by Sackett and Dreher (1982) is presented. Their major finding, indicating that assessment centers lack key tenets of internal construct validity, was corroborated in this study of a hotel managers' assessment center. This hotel managers' assessment center is also found to be externally valid using criterion-related validity. The argument is posed that assessment centers, as standardized tests of complex behavioral traits, appear to be operating outside the bounds of normal test construction principles. Five key explanations for this paradox are offered to guide much needed future research in this area. Additionally, a description of commonly utilized assessment center activities is offered the reader.

This study examined the validity of the Minnesota Multiphasic Personality Inventory (MMPI) as a predictor for police officer selection. The MMPI profiles of 212 police officer applicants selected to enter the training academy were compared to the standardized MMPI norms. Significant differences between the police officers and the normative population were found on all but two scales. When the average profile of officers still on the police force was compared with the average profile of terminated officers, two scales were significantly different. Significant correlations were obtained between four MMPI scales and the academy score criterion and two scales each for the commendation and supervisory rating criteria. A prediction equation was developed for academy score using multiple regression analysis.

Five learning measures used in a skills training program were related to three types of job performance measures for a sample of 163 oil field employees. Statistical analyses resulted in only modest correlations between learning and job performance criteria. Factor analyses of learning measures followed by multiple regression on factors yielded a significant R with only one criterion measure. It was concluded from these data that the training program was of minimal value. The discussion centered on strategies for better training, training research, job engineering, and correcting the two limitations of this study.

The study examined the validity of using the California Psychological Inventory (CPI) as a tool for police selection. The mean CPI profile of 211 police applicants was first compared to that of the CPI norms. Five performance criterion measures--retention on the job, academy grades, supervisory ratings, commendations, and reprimands of police officers--were studied to investigate their relationships with the CPI scales. The results indicated that there were significant mean differences on all the CPI scales between police applicants and CPI norms. The scale of Flexibility significantly differentiated the criterion groups of retention on the job. The CPI was useful in predicting academy performance; however, it did not correlate well with job performance as measured by supervisory ratings, commendations, and reprimands.
