The constitution mandates free and compulsory primary education in the Gambia. Lack of resources and of educational infrastructure has made implementation of this difficult. In 1995 the gross primary enrolment rate was 77.1% and the net primary enrolment rate was 64.7% School fees long prevented many children from attending school, but in February 1998 President Jammeh ordered the termination of fees for the first six years of schooling. Girls make up about 52% of primary-school pupils. The figure may be lower for girls in rural areas, where cultural factors and poverty prevent parents from sending girls to school. Approximately 20% of school-age children attend Quranic schools.
