Because internal trainers generally do not have rich training experience, it is of great significance to carry out certain assessment and evaluation to improve the level of internal trainers and help them quickly find their own shortcomings and deficiencies. In the evaluation process, we need to pay attention to the following questions:

First of all, training evaluation should not be limited to the late stage of the training course or after the training course. Enterprises need to have a relatively perfect training course monitoring system, so as to effectively avoid out-of-control training courses. Therefore, for training courses, especially those with a long cycle, enterprises need to conduct certain evaluation and inspection at the beginning and midway of the course, so as to find out the possible problems in training progress, methods and methods in time and make corresponding corrections and remedies.

Secondly, in the process of evaluation, we should make clear the standards and scales of evaluation. Generally speaking, in the process of evaluation, enterprises need to formulate a relatively perfect evaluation form according to the training objectives and preliminary training plans, so that the evaluation can be targeted and avoid being too vague and subjective.

Thirdly, training evaluation should start from two aspects, not limited to one aspect: on the one hand, it should evaluate the training materials, training contents, training methods and methods of internal trainers; On the other hand, it is to evaluate the students' gains after training, that is, whether the students' professional knowledge or vocational skills are improved, whether their work attitude is improved, and whether their work performance is improved, so as to truly evaluate the training effect. At present, the feasible methods are: examination comparative evaluation method, work performance evaluation method, work attitude inspection evaluation method, work standard comparative evaluation method, similar employees comparative evaluation method, reference to superior or subordinate opinions evaluation method and so on. The connotation and extension of these evaluation methods are constantly improved in practice, and their advantages and disadvantages are still different. However, with the establishment of enterprise internal training system, its scientific and effective evaluation system will be formed.
