The education system comprised three stages: primary school lasted six years, leading to a certificate of primary studies; secondary school lasted seven years, leading to a certificate or baccalauréat. University education, available only in Abidjan, culminated in a university degree. A large number of technical and teacher-training institutions also provided post primary and post secondary education. There was no system of adult education, although many adults attended night courses or, in rural areas, received literacy and other instruction via radio. Most public schools were tuition free, although students pay an entrance fee and buy uniforms. Most supplies were free, and some students received government scholarships, usually in return for a period of government employment after graduation.
