Attempted to determine whether there are attitudinal improvements and performance increases associated with the use of behavioral expectation scales (BESs). A longitudinal research design using 3 data measurement points and covering 20 mo was used; 306 discipline engineers and their supervisors participated. Analysis of covariance, ANOVA with repeated measures, and planned comparison tests were used to examine the data. BES-rated engineers reported more favorable attitudes about performance evaluation properties, less job related tension, and increased scheduling performance than their counterparts, who were rated with the organization's regular trait evaluation system. Findings occurred in the absence of any formal training program for raters using the BES, and they were being sustained 18 mo after the BES system was implemented.
