Pre—Post-Training Performance Method In the pre—post-training performance Method, each participant is evaluated prior to training and rated on actual job performance. After instruction—of which the evaluator has been kept unaware—is completed, the employee is reevaluated. As with the post-training performance method, the increase is assumed to be attributable to the instruction. However, in contrast to the post-training performance method, the pre—post-training performance method deals directly with job behavior.
