The purpose of this study is to provide basic data necessary for operating corporate education by analyzing the impact of corporate education on students' achievement in specialized areas of professional education by major factors, corporate education factors, and school education factors. The specific results are as follows. First, after participating in corporate training, learning orientation, self-control, value awareness, and confidence in specialized subject classes increased, but anxiety and interest had a relatively low impact. Second, as a result of analysis by major factors, industrial majors such as machinery, electricity/electronics, and information and communication showed lower scores than other majors in the overall affective domain. Third, as a result of analysis by corporate education factors, the higher the satisfaction with corporate education and the satisfaction of corporate field teachers, the higher the students' achievement in the positive areas of specialized subjects. As a result of analyzing the differences according to corporate training methods, the formal learning method was 'passing on knowledge and skills directly while performing tasks or tasks with an apprentice', 'transferring knowledge through lectures, assigning tasks to apprentices and checking periodically'. , it was found that the method of ‘letting apprentices learn textbooks or learning tools on their own and checking the learning results’ had a higher impact on achievement in the affective domain than the method of ‘working similarly to other employees’. Fourth, the results for each school education factor showed that the more visits, consultations, and participation in corporate education guidance by school teachers, the higher the achievement in the affective area.
