An estimated 3.7 million children are out-of-school in Afghanistan. 60 per cent of girls and 46 per cent of boys of primary school age are currently not attending any level of education in Afghanistan. Even when children are enrolled in school, they are not always learning. Years of previous conflict, coupled with poor infrastructure, have made some schools unsafe for children. Many public schools lack adequate classrooms, qualified teachers, school supplies, and places where children can wash their hands.
