This study evaluates the impact of school-based behavioral "nudges" installed in toilets and handwashing facilities on handwashing behavior among students in the Philippines. Nudges include: visible signage crafted to trigger behavioral motivators for handwashing; colorful pathway overlaid with footprints leading from the toilet to the handwashing station; sticker of a pair of eyes placed above the handwashing station; soap dish with an arrow beside it on the sink or counter to remind children to wash their hands with soap. The study's main hypothesis is that behavioral nudges will increase the percentage of students who wash their hands with water and soap after toilet use by 7 percentage points or more among schools where nudges were installed compared to control schools without nudges. The study is taking place in public primary schools in Zamboanga Del Norte, Philippines between October 2019 and May 2020.
