Forced‐choice (FC) measures are becoming increasingly common in the assessment of personality for high‐stakes testing purposes in both educational and organizational settings. Despite this, there has been relatively little research into the reliability of scores obtained from these measures, particularly when administered as a computerized adaptive test (CAT). This study examined the test–retest reliability of an FC personality CAT, comparing its reliability to the reliability of personality measures using a Likert‐type rating scale. Using a relatively large sample ( N = 743), participants completed multiple personality measures across two time points. The test–retest reliability estimates for the personality dimensions had a mean of .63 with a mean reliability of .73 when formed into Big Five personality trait composites. The FC personality reliabilities were lower than those of the Likert‐type scales, though the findings are within the range of those found in meta‐analytic studies.
