Over the past 15 years, girls' education in the developing world has been a story of progress. Interest and financial backing from the development community have grown steadily in response to accumulating evidence documenting the many benefits of girls' schooling, and female education is now a major part of global development commitments, including the Millennium Development Goals.The information collected for this report suggest that relatively few programs are specifically designed with the developmental and learning needs of adolescent girls in mind. Rather, the evidence suggests that adolescents girls are often subsumed under programs for younger girls or adult women. Our compendium of policies and programs also suggests that skillá development and knowledge acquisition vary enormously by grade level, both within and across countries, due to variations in school quality.
