"A handwashing station will be a dedicated location for handwashing in each selected school and will include:~1. A raised concrete platform (built to child height)~2.

A plastic container with a lid and spigot~3. Soap~The late handwashing stations construction will begin after Phase 2 data collection has been finished at the end of week 3."

"A nudge will be built in each randomly selected school and will consist of:~1. Connecting latrines to the handwashing station via paved pathways that are painted bright colors~2. Painting footprints on infrastructure guiding students to the handwashing stations and handprints on stations~The nudges will be constructed at the end of week 3 and 4, after Phase II data collection is complete within each randomly assigned nudge school."

"Hand hygiene education-based program: the hygiene promotion element will include a one month program of handwashing education involving weekly facilitator led sessions. Each session will be about 30-45 minutes long, and will cover the following topics:~* Importance of handwashing~* Method of handwashing~* Critical times of handwashing~* Finding solutions for handwashing in school and at home The sessions will involve use of flipcharts, and other IEC materials (e.g. videos) and participative learning methods.~The Hand hygiene education-based program will begin at the beginning of weeks 4 and 5, after Phase II data collection is complete in each randomly assigned education school."
