Providing free breakfast in schools before the school day produced measurable gains in academic attainment equivalent to two additional months of learning, particularly for younger children. Attendance also improved. The cluster-randomized design allowed for school-level assignment that avoided contamination between conditions. The Welsh program has since become a model for breakfast-in-schools policies across the UK.
