Full Studies: Project WISE Phase 1 Research

Across Project WISE Phase 1, Splash and independent researchers studied 537 schools in Addis Ababa, Ethiopia and Kolkata, India, tracking water quality, handwashing behavior, sanitation infrastructure, and menstrual health to understand not just what changed, but what lasted. The five studies below share the complete findings.

Behavior Change

At Splash, we continuously assess the impact of our programs to ensure they benefit children, families, and communities.

To achieve this, we've developed a robust global monitoring, evaluation, and learning (MLE) framework that combines our theory of change with data analysis, known as "learning loops." These loops can span years and involve rigorous trials for fundamental ideas, while others are short-term and rely on dynamic information systems for quick decision-making. We tailor our approach to provide decision-makers with precise information when they need it, at the right level of confidence. Learn more about how we measure our impact here.
