By 1985 there were more than 1,000 teacher training schools - an indispensable tool in the effort to solve the acute shortage of qualified teachers. These schools, however, were unable to supply the number of teachers needed to attain modernization goals through 1990. Although a considerable number of students graduated as qualified teachers from institutions of Higher Learning, the relatively low social status and salary levels of teachers hampered recruitment, and not all of the graduates of teachers' colleges became teachers. To attract more teachers, China tried to make teaching a more desirable and respected profession. To this end, the government designated 10 September as Teachers' Day, granted teachers pay raises, and made teachers' colleges tuition free. To further arrest the teacher shortage, in 1986 the central government sent teachers to underdeveloped regions to train local schoolteachers.
