School health and nutrition programs can contribute to achieving the goals of the Education for All initiative (EFA) by helping children enroll on time, complete their education, and realize their cognitive potential. Achieving these goals depends on reaching the children most in need. One strong feature of school health and nutrition programs is that they benefit the poor, sick, and hungry children far more that better-off children. However, poor children can only benefit if the programs reach them. This book describes how schools have been used as a platform for delivering safe and simple health and nutrition programs to even hard-to-reach children in low-income countries.
