A new report by the South African Institute for International Affairs (SAIIA) has highlighted the challenges and constraints facing education in Africa. According to the Johannesburg-based think tank, more than 40 million children of primary school age in sub-Saharan Africa are not receiving an education, (this amounts to almost half the children on the continent who should be in primary school). Enrolment in secondary school in 22 countries is below 20 percent, and less than 10 percent of the workforce has completed secondary school.
