Behavioral Assessment Scales

BARS (behavioral anchored rating scale)

The Behaviorally Anchored Rating Scale (BARS) was developed to correct the problem of vague statements on traditional graphic scales.

This method uses specific descriptions of actual behaviors along the various points on the measurement scale.

The scale compares the employee's work behaviors to pre-established statements that define what is considered good or poor performance on a specific task.

Because it is based on examples of critical behavior, it provides more accurate measurement standards and reduces ambiguity in the evaluator's interpretation.

This system is especially valuable for giving clear feedback to the worker, as it allows him/her to understand exactly what specific actions to replicate or avoid in order to improve his/her score in the next evaluation cycle.

BOS (frequency observation) scale

The Behavioral Observation Scale (BOS) differs from the BARS method by focusing primarily on the frequency with which desired or undesired behaviors occur on the job.

The evaluator does not judge whether the behavior is "good" or "bad" per se, but rather records how many times the worker exhibits specific actions that have been identified as critical to the success of the position.

On the other hand, there is the Behaviorally Anchored Discipline Scale, which focuses specifically on negative behaviors or misconduct, such as absenteeism or safety incidents.

The use of these behavioral scales professionalizes the evaluation by basing it on factual and observable evidence, which minimizes disputes about the fairness of the process and allows the development of human talent to be guided by clear behavioral indicators aligned with the institutional mission.
