The Korean Ministry of Science and Technology announced a long-term demand suppley programs of man power, in which we should train about 1,800,000 technicians between 1973 and 1981. The technical high schools are charged with the education. of 840,000 technicians. This paper is a proposal for an improved course of education in the mechanical departments of technical high schools. All kinds of typical high schools with mechanical departments were visited and the directors and techers were consulted regarding their education courses. Questionaires were mailed to technical high schools and key enterprises to determin the present situations of the students and graduates from their many-sided viewpoints. The findings, in brief, are as follows: 1. All students should work in industry for 6 months. 2. Qualified technicians in industry should train the students systematically. 3. The education of the technical high schools can not be relied on as the only training for the qualification examination. 4. It is necessary that technical high schools should give more importance to the culture of sentiments.
