The Utility of the Assessment Center as a Selection Device.
Cascio, Wayne F.; Silbey, Val
Psychometric evaluations of the assessment center method of personnel selection have consistently shown positive results. However, this approach ignores certain external parameters (e.g., selection ratio, cost of the procedure) which largely determine the overall utility of a selection device. Moreover, the psychometric evaluation approach ignores the systemic nature of the selection process. Utility theory attempts to overcome these deficiencies by placing primary emphasis on the outcomes of prediction, rather than on measurement and prediction per se. The utility of the assessment center was evaluated by means of the Brogden-Cronbach-Gleser continuous variable utility model. After specifying several cost assumptions, six parameters were varied systematically: the validity and cost of the assessment center; the validity of the ordinary selection procedure; the selection ratio; the standard deviation of the criterion; and the number of assessment centers. The largest impacts on assessment center payoff were exerted by the size of the criterion standard deviation, the selection ratio, and the difference in validity between the assessment center and the ordinary selection procedure. Even assessment centers with validities as low as .10 still showed positive gains in utility over random selection. (Author/MH)
