Millions of young girls never attend school. Millions more never complete their education. As they grow, they are unable to participate fully in the political, social and economic development of their communities. They and their children are at greater risk of HIV/AIDS, sexual exploitation, violence and abuse. This publication, reprinted from The State of the World's Children 2004, describes key strategies that can be used to ensure that more girls attend and complete school, while providing examples of successes in several countries.
