摘要

Despite recent interest in the practice of allowing job applicants to retest, surprisingly little is known about how retesting affects 2 of the most critical factors on which staffing procedures are evaluated: subgroup differences and criterion-related validity. We examined these important issues in a sample of internal candidates who completed a job-knowledge test for a within-job promotion. This was a useful context for these questions because we had job-performance data on all candidates (N = 403), regardless of whether they passed or failed the promotion test (i.e., there was no direct range restriction). We found that retest effects varied by subgroup, such that females and younger candidates improved more upon retesting than did males and older candidates. There also was some evidence that Black candidates did not improve as much as did candidates from other racial groups. In addition, among candidates who retested, their retest scores were somewhat better predictors of subsequent job performance than were their initial test scores (rs = .38 vs. .27). The overall results suggest that retesting does not negatively affect criterion-related validity and may even enhance it. Furthermore, retesting may reduce the likelihood of adverse impact against some subgroups (e. g., female candidates) but increase the likelihood of adverse impact against other subgroups (e. g., older candidates).
