Using both the Behaviorally Anchored Rating Scales (BARS) and the Purdue University Scales, 727 undergraduates rated 32 instructors. The BARS had less halo effect, more leniency error, and lower interrater reliability. Both formats were valid. The two tests did not differ in rate discrimination or susceptibility to rating bias.
