mental ability (GMA) and Ihe 18 other selection procedures. Overall‚ the 3 combinations with the highest multivariate validity and utility for job performance were GMA plus a work sample test (mean validity of .63)‚ GMA plus an integrity test (mean validity of .65)‚ and GMA plus a structured interview (mean validity of .63). A further advantage of the latter 2 combinations is that they can be used for both entry level selection and selection of experienced employees. The practical utility implications

They could turn the lights on and off as they wished. After a month
