A school-based water, sanitation, and hygiene (WASH) intervention in the Philippines was evaluated. Students and households from four schools that received the WASH intervention (intervention schools) were compared with four schools that had not (comparison schools). Knowledge of critical handwashing times was high across all schools, but higher in intervention schools. Students reported higher rates of handwashing after toilet use (92% vs. 87%; RR = 1.06; p = 0.003) and handwashing with soap (83% vs. 60%; RR = 1.4; p < 0.001) in intervention versus comparison schools. In intervention schools, 89% of students were directly observed to handwash after toilet use versus 31% in comparison school..
