As part of its note series, this paper by the World Bank looks at case study examples of: Burkino Faso, Laos and Uganda which evaluates the experiences of these three countries and points to the possibilities and limitations of school feeding programs based on different methods of implementation.

When properly implemented, they can raise enrolment and possibly lead to better learning. But even then, feeding programs are unlikely to make up for the cognitive and physical lags that result from poor nutrition during pregnancy and the first two years of life.
