Behaviorally anchored rating scales (BARS) are rating scales whose scale points are defined by statements of effective and ineffective behaviors. They are said to be behaviorally anchored in that the scales represent a continuum of descriptive statements of behaviors ranging from least to most effective. An evaluator must indicate which behavior on each scale best describes an employee's performance.
BARS differ from other rating scales in that scale points are specifically defined behaviors. Also, BARS are constructed by the evaluators who will use them. There are four steps in the BARS construction process:
1. Listing of all the important dimensions of performance for a job or jobs
2. Collection of critical incidents of effective and ineffective behavior
3. Classification of effective and ineffective behaviors to appropriate performance dimensions
4. Assignment of numerical values to each behavior within each dimension (i.e., scaling of behavioral anchors)
