Expenditure on education doubled, the number of years of basic education was increased from six to eight, and a two-shift school-day was introduced that doubled the capacity of the country's system. Frei's initiatives in education led to increased rates of enrollment in both primary and secondary education, with primary school coverage reaching 90% in the majority of rural and urban areas by 1970, while secondary school coverage reached 49% in 1970, compared with 18% at the start of the 1960s.Pribble (2008), pg. 136
