A behaviorally anchored rating scale (BARS) form is a performance appraisal that provides a description of each assessment along a continuum. As with graphic rating scales, the continuum often includes a numerical scale that runs from low to high; but with the BARS form, each item is an analysis of a specific behavior.

BARS forms overcome the problem of subjectivity by providing an actual description of the performance (the required behaviors) for each rating along the continuum, rather than that one simple word (excellent, good, etc.) that graphic rating scales provide. A description of each level of performance makes the assessment a more objective, accurate measure.

Again, the graphic rating scale can be used for many different jobs, but BARS forms have to be customized to every different type of job. And developing potentially hundreds of different BARS forms takes a lot of time, money, and expertise.

As with graphic rating scales, we simply select a level of performance along a continuum.
