The net enrolment ratio in primary education in the developing regions increased to 88 per cent in the school year 2004/2005, up from 80 per cent in 1990/1991. Two thirds of the increase occurred since 1999. Although sub-Saharan Africa has made significant progress over the last few years, it still trails behind other regions, with 30 per cent of its children of primary school age out of school. A strong push will be needed over the next few years to enrol all children in school and to fulfil their right to a quality education.
