This paper attempts to reveal the effectiveness of the package of water, sanitation and hygiene (WASH) interventions
with the school students’ network “student brigades” in terms of their impacts on water and sanitation (or WATSAN)
behavior of household members both in household and farm level and on their health and productivity outcomes. We
conduct Randomized Control Trial (RCT) with students’ brigades in six WATSAN hotspots (sub-districts) of
Bangladesh in several phases: a water quality census, baseline survey, treatment implementation at treatment areas
and end line survey. Our treatment consists of three actions: informing the households about the prior water testing
results, delivering hygiene messages through a poster and equipping the student brigades with water testing toolkits
and letting them test water at different points and communicate the results back to their households. Impression from
the implemented treatments indicates that the suggested intervention package can be an effective strategy to motivate
households and communities, particularly by using school students as the agents of change.
