RELATION OF JOB QUALIFICATION RATINGS TO PERFORMANCE RATINGS OF BASIC TRAINING INSTRUCTORS,
Abstract
Among the many studies of selection and classification instruments, few have shown high relationship between selection tests and job performance ratings. It was hypothesized that some of the prediction failures could arise from mixing jobs with dissimilar requirements in the criterion data. The job of tactical instructor (TI) was selected to test whether a job requiring all incumbents to perform the same tasks would yield reliable performance data which would be predictable from a battery of qualifications ratings. 55 NCO supervisors rated 527 TIs on overall job performance and on 45 job qualification characteristics. By multiple regression techniques, it was found that characteristics ratings accounted for 75% of the variance in the overall ratings. 3 months later 53 of the supervisors rerated 482 TIs. The correlation between the 2 ratings (reliability) was .72. Overall ratings of 309 TIs by 12 supervisory lieutenants correlated .63 with the reratings. Ratings of the 45 characteristics accounted for 60% of the rerate variance and 50% of the variance of lieutenants' ratings. The findings are consistent with the hypothesis that some of the unpredictability of job performance ratings may be due to mixing dissimilar jobs in collecting criterion data. (Author)
