Training evaluation is the process of describing and comprehensively evaluating the training system, and making "good" or "bad" training items.Evaluation is only a superficial level of performance, but to improve the training through the information obtained. Goldstein starts with a psychological theory,A series of measurement models for training evaluation are proposed. Kirkpatrick (1959) proposed the "four-level model" of training evaluation.That is, the four-level evaluation method of "reaction to learning-behavior result" 1401. The first is response assessment, which evaluates the trainer against the training organizationThe degree of satisfaction in work, training environment, training content, training form, teaching staff, etc.; The second is learning assessment,Organize trainees to test the content of training courses to assess the level of learning of the trainees; The third level is behaviorEvaluate and track the trainer's knowledge utilization during a period of time after the training, so as to observe the training learningTransformation and application of results; The last layer is the evaluation of the results. After the training, the training data should be counted and the training should be conductedThe data collected before are compared to calculate the economic benefits of training. Then, on the basis of the four-tier model,Many scholars have established different evaluation models based on the consideration of pre-test, post-test and utility, such as the CIRO four-level evaluation model,The five-level return on investment evaluation model (RO), CIPP model and so on have made more explanation and application to the training evaluation theory
