Document Summary
Difference between concurrent and predictive validity studies: concurrent validation uses incumbents as participants rather than applicants. In concurrent validation, both predictors and criteria are measured at the same time. Usefulness of selection process: the answer to is it worth it? often comes directly from an assessment of utility, elements of selection process that allows use to assess utility, decision accuracy, validity, base rate, selection ratio, cost. Validity: to the extent that a selection battery is valid, hits and correct rejections will be maximized while misses and false alarms will be minimized, with larger validity coefficients, predictors do a better job of forecasting subsequent performance. Selection ratio: number of job openings dividied by number of applicants. If 20 openings and 20 applicants, then sr=1. 00; if 5 openings for 20 applicants, then. Sr=0. 25: the smaller that sr, the greater the potential utility of the selection battery. Cost: associated with the development and implementation of a selection battery.
