Test-Retest Reliability of Ratings of Job Performance Dimensions in Managers

This article examines the test-retest reliability of supervisory ratings for several dimensions of job performance and for overall job performance. We found that the test-retest reliability of overall job performance is .79 (SD=.08), a value very close to the one found by Viswesvaran, Ones and Schmidt (1996), and that the average test-retest reliability for specific dimensions of job performance is .57 (SD=.07). We also found that some dimensions of job performance appear to be easier to rate than others. We suggest some implications of these findings for research and practice of personnel selection
