“Global education plays an important role in contributing to U.S. foreign policy objectives. In a recent speech, Secretary of State Hillary Clinton highlighted education, along with health, agriculture, security, and local governance as the core areas for U.S. international development investment. She emphasized the importance of education, particularly of girls and youth, in improving global stability, speeding economic growth, and helping global health, all of which advance U.S. interests in the world.But how effective has the U.S. government been in supporting global education? Unfortunately, its many good education activities and programs are not leveraged for maximum impact on the ground, especially in situations of armed conflict and state fragility. Challenges of U.S. foreign assistance—for example, fragmentation across multiple agencies, lack of policy coherence, diminished multilateral engagement—generally affects its work in education. Luckily some of the core strengths of U.S. assistance have an impact as well, specifically the large amount of resources (in total terms, if not relative terms) devoted to education and the vast breadth and depth of American academic, philanthropic and NGO partners engaged in pioneering work on education in the developing world.”*
