The government established a six-year primary cycle followed by four years of intermediate schooling and two years of secondary school ending with the baccalaureate degree. Laws in 1969 and 1973 revised the curricula and instituted a five-year primary cycle, theoretically compulsory between the ages of seven and fourteen, followed by three years of intermediate school and four years of secondary education. The first two years of secondary instruction consisted of an integrated program that all students followed; the second two-year cycle permitted students to specialize in the humanities or one of several technical fields.
