This study was carried out to determine the knowledge(K), attitude(A) and practice(P) on major industrial safety and health problems among on-the-job training students.

We used self-administered questionnaire regarding rules or regulations, the management of hazardous materials, the work place hygiene, the use of protective device, arrangement and improvement job site, ventilation, safety and health education, and inspection and management of equipment.

In general, the mean score of KAP in educated group compared with non-educated group was significantly higher. As increasing the frequency of education, the mean scores of KAP were increased. There were not significant differences among 'work duration' groups on total mean scores of knowledge and practice. But on that of the attitude, there was significant differences among 'work duration'groups. There were significant differences among 'size of enterprise'groups on total mean scores of knowledge and attitude. But on that of the practice, there was no significant differences among'size of enterprise' groups. In stepwise multiple regression analysis, education frequency and method were significantly attributed to KAP, but the coefficient of determination were low.

it is suggested that the increase of education time was the most important thing for improving the knowledge, attitude and practice on industrial safety and health in technical high school students.
