Rating Attributes The most widely used method for rating attributes is the graphic rating scale. This method lists traits and provides a rating scale for each trait. The employer uses the scale to indicate the extent to which the employee being rated displays the traits. some organizations use mixed-standard scales, which use several statements describing each trait to produce a final score for that trait. The manager scores the employee in terms of how the employee compares to each statement.Rating Behaviors One way to overcome the drawbacks of rating attributes is to measureemployees’ behavior. To rate behaviors, the organization begins by defining whichbehaviors are associated with success on the jobCritical-Incident Method :Method of performance measurement based on managers’ records of specific examples of the employee acting in ways that are either effective or ineffective.Behaviorally Anchored Rating Scale (BARS):Method of performance measurement that rates behavior in terms of a scale showing specific statements of behavior that describe different levels of performance Behavioral Observation Scale (BOS)A variation of a BARS which uses all behaviors necessary for effective performance to rate performance at a task. Organizational Behavior Modification (OBM)A plan for managing the behavior of employees through a formal system of feedback and reinforcement.
