The popularity of school feeding programs make it imperative that we answer basic questions about the effectiveness of these programs. Do they boost enrollment and if so, are take-home rations as good as offering in-school meals? A proper lunch can ward off hunger, but is it enough to make up for years of nutritional deprivation? Children who aren’t hungry can focus better in school—does this mean they will do better in their classes? The answers are critical if we want to create effective development programs.
