Evaluation before the training is performed to check whether applicants are equipped with knowledge and skills to participate in the training. It includes screening tests for enrollment in the course and class placement tests. Training evaluation after training is performed to certify that the trainees have mastered the training content and can use it on the job. In Japan’s public VT, trade skill verification mentioned in “1.3.3. (5) Trade skill verification” is implemented. Because both involve considerable cost, each of them can be implemented only once or so. Therefore, their development requires ample studies.
