A common model for summative training evaluation was developed by Donald Kirkpatrick. He proposed four levels of evaluation for training programs: reaction, learning, behavior, and results. Measurements at each level are based on the objectives developed during the design phase:Reaction The reaction evaluation method measures the initial reaction of the participants. This is most commonly determined by a survey completed by participants at the end of the training. Although this level of evaluation doesn’t measure the organization impact, it does provide feedback for the trainer in terms of the presentation of the information.Learning The learning evaluation method uses a test to measure whether the participants learned the information that was presented. Although this level of evaluation provides more information about the effectiveness of the training, it still doesn’t provide feedback about the application of the information on the job.
