through a series of reforms which also affected educational development. By early 1975, the government had closed Haile Selassie I University and all senior secondary schools, then deployed the approximately 60,000 students and teachers to rural areas to promote the government's "Development Through Cooperation Campaign". The campaign's purposes were to promote land reform and improve agricultural production, health, and local administration and to teach peasants about the new political and social order. Primary school enrollment increased from about 957,300 in 1974/75 to nearly 2,450,000 in 1985/86. There were still variations among regions in the number of students enrolled and a disparity in the enrollment of boys and girls. Nevertheless, while the enrollment of boys more than doubled, that of girls more than tripled. However, with most of the rebel controlled northern Ethiopia regions as well as parts of Somali and Oromo regions out of the government's control, most of its claims were not perceived to be comprehensive. The number of senior secondary schools almost doubled as well, with fourfold increases in Arsi, Bale, Gojjam, Gondar, and Wollo. The pre-revolutionary distribution of schools had shown a concentration in the urban areas of a few administrative regions. In 1974/75 about 55 percent of senior secondary schools were in Eritrea and Shewa, including Addis Ababa. In 1985/86 the figure was down to 40 percent. Although there were significantly fewer girls enrolled at the secondary level, the proportion of females in the school system at all levels and in all regions increased from about 32 percent in 1974/75 to 39 percent in 1985/86. Among the PDRE's successes was the national literacy campaign. The literacy rate, under 10 percent during the imperial regime, increased to about 63 percent by 1984. In 1990/91 an adult literacy rate of just over 60 percent was still being reported in government as well as in some international reports. As with the 1984 data, it several wise to exercise caution with regard to the latest figure. Officials originally conducted the literacy training in five languages: Amharic, Oromo, Tigrinya, Wolaytta, and Somali. The number of languages was later expanded to fifteen, which represented about 93 percent of the population. A number of countries were generous in helping the PDRE meet its health care needs. Cuba, the Soviet Union, and a number of East European countries provided medical assistance. In early 1980, nearly 300 Cuban medical technicians, including more than 100 physicians,
