To improve social and economic conditions for women, the Women's Secretariat was established in 1971, which took on issues such as public laundry facilities, public food programs, day-care centers, and women's health care (especially prenatal care). The duration of maternity leave was extended from 6 to 12 weeks, while the Allende Government steered the educational system towards poorer Chileans by expanding enrollments through government subsidies. A "democratisation" of university education was carried out, making the system tuition-free. This led to an 89% rise in university enrollments between 1970 and 1973. The Allende Government also increased enrollment in secondary education from 38% in 1970 to 51% in 1974. Enrollment in education reached record levels, including 3.6 million young people, and 8 million school textbooks were distributed among 2.6 million pupils in primary education. An unprecedented 130,000 students were enrolled by the universities, which became accessible to peasants and workers. The illiteracy rate was reduced from 12% in 1970 to 10.8% in 1972, while the growth in primary school enrollment increased from an annual average of 3.4% in the period 1966–70 to 6.5% in 1971–1972. Secondary education grew at a rate of 18.2% in 1971–1972, and the average school enrollment of children between the ages of 6 and 14 rose from 91% (1966–70) to 99%.
