Under the educational reform tenets, polytechnic colleges were to give priority to admitting secondary vocational and technical school graduates and providing on-the-job training for qualified workers. Education reformers continued to press for the conversion of about 50 percent of upper secondary education into vocational education, which traditionally had been weak in the rural areas. Regular senior middle schools were to be converted into vocational middle schools, and vocational training classes were to be established in some senior middle schools. Diversion of students from academic to technical education was intended to alleviate skill shortages and to reduce the competition for university enrollment.
