Education is a driver of social, economic and political progress. As girls learn to read, their prospects for leading a healthy, more prosperous life expand exponentially. Advances in education have not benefited everyone equally. Major barriers to school enrollment and completion include gender disparities. Girls face a unique set of barriers to education including child marriage, early pregnancy, and expectations related to domestic labor. About 34 million adolescent girls are out of school today. The gender gap has significantly narrowed in primary education but there has been limited progress at the secondary level.
