Through its Global Scaling Up Handwashing project, WSP supported government partners to apply innovative behavior change approaches to improve handwashing with soap behavior at-scale among women and young children in Peru, Senegal, Tanzania, and Vietnam. The project had four components: changing handwashing behavior at-scale; creating an enabling environment to ensure the sustainability of the interventions; monitoring and learning; and evaluating impact. The modules within this toolkit capture the experiences and lessons learned from the project, which was implemented by local and national governments with technical support from WSP.

The modules have a common organizational structure. Each module has a Key Terms section, where you can find definitions for concepts used throughout the toolkit. The section Keep in Mind contains key tips learned during the course of this project. In addition, you will find tools and resources, such as a page for each of the four countries, which shares documents, videos, and other materials used during implementation.
