Evidence Action scales proven interventions that improve the lives of millions. We only implement cost-effective programs whose efficacy is backed by substantial rigorous evidence. We identify innovative, appropriate financing mechanisms and build best-practice operational models. We voraciously self-evaluate, learn, and improve our models for scaling effective interventions with a commitment to transparency, impact, and value for money. Our current flagship programs include: Dispensers for Safe Water; an entrepreneurial program scaling the chlorine dispenser system to 25 million people by 2018. Dispensers for Safe Water is a proven innovation that dramatically expands access to safe drinking water at an extremely low cost. Deworm the World Initiative actively supports governments to scale school-based deworming programs to eliminate the worldwide public health problem of worms, and improve children's health, education, and long-term development.
