China's educational television system began in 1960 but was suspended during the Cultural Revolution in 1966. In 1979 the Central Radio and Television University was established in Beijing with branches in twenty-eight provincial-level universities. Many Central Radio and Television University students were recent senior-middle school graduates who scored just below the cut-off point for admission to conventional colleges and universities. Full-time (who take four courses) and part-time students (two courses) had at least two years' work experience, and they return to their jobs after graduation. Spare-time students (one course) studied after work. Students whose work units granted them permission to study in a television university were paid their normal wages; expenses for most of their books and other educational materials were paid for by the state. A typical Central Radio and Television University student spent up to six hours a day over a three-year period watching lectures on videotapes produced by some of the best teachers in China. These lectures were augmented by face-to-face tutoring by local instructors and approximately four hours of homework each evening. The major problem with the system is that there were too few television sets. In 1987 the Central Television and Radio University had its programs produced, transmitted, and financed by the State Administration of Radio, Film, and Television. The State Education Commission developed its curriculum and distributed its printed support materials. The curriculum included both basic, general-purpose courses in science and technology and more specialized courses. The Central Television and Radio University offered more than 1,000 classes in Beijing and its suburbs and 14 majors in 2- to 3-year courses through 56 working centers. Students who passed final examinations were given certificates entitling them to the same level of remuneration as graduates of regular, full-time colleges and universities. The state gave certain allowances to students awaiting jobs during their training period.
