In practical terms the 1959 reforms introduced a unified twelve-year so-called secondary school--despite the fact that it included the elementary grades as well--called the medium polytechnical school, which totally replaced the existing five-year basic school and the four-year medium school or gymnasium. The medium polytechnical school was divided into an eight-year elementary course and a four-year upper course. After completing the basic school the student was faced with four alternatives. He could enter: the upper course, which provided general education plus specialization in an area of production; a medium professional school or technicum, which provided a specialized education; a professional technical college, which prepared him for production in the economy; or the so-called miscellaneous training, which included courses organized by plants, factories, and cooperatives. At the same time the new law provided for the improvement of teacher training. All teachers who taught in the fifth level or above were required to have a university education or its equivalent. Teachers who taught in kindergartens or the first to fourth levels were required to take a three-year course after the obligatory twelve-year course of schooling. The reforms were later criticized, however, on much more far-reaching grounds. Some felt that technical specialization was stressed to such an extreme that the liberal arts were altogether ignored. Some complained that, although students were overburdened with superfluous details of overspecialized subjects, teachers were still basically unprepared to teach these subjects. Others felt that there was a lack of correlation between the work that the student had to perform and his or her area of expertise. Still others realized that there was a basic clash between the managers who supervised the worker-students and the students themselves. Despite much criticism about the reforms, in terms of bare statistics they were successful in greatly increasing the emphasis on technical-vocational training. Although the number of primary and secondary students remained approximately at the same level and the number of primary and secondary schools declined drastically, there was a tremendous increase in technical-vocational schools, students, and teachers.
