Behaviorally Anchored Rating Scales developed according to Bernardin, LaShells, Smith, and Alvarez's (1976) optimal procedure was compared with a carefully constructed summated rating scale. Using both scales, 727 undergraduates rated 32 instructors. Psychometric comparisons indicated that BARS had less halo error, more leniency error, and lower interrater reliablity than the alternative format. The two formats did not differ in ratee discrimination and susceptibility to rating bias due to rater characteristics. Finally, the formats contained convergent and discriminant validity.
