In the largest evaluation of water, sanitation, and hygiene (WASH) programming to date, World Vision and the University of North Carolina Water Institute partnered together to assess over 36,000 households, 2,532 water points, 2,691 schools, and 2,035 healthcare facilities in 14 countries. The study, completed in 2017, aimed to: 1) survey the state of WASH in 14 countries, and 2) assess the status of WASH in World Vision program areas compared to non-World Vision program areas in these countries. Though this study did not analyze specific World Vision interventions, the findings provide a snapshot of WASH access around the world and can help determine whether or not World Vision programming is consistently effective in improving the quality and sustainability of WASH systems.
