The main aim of this project was to undertake participatory action research in two primary schools in northern Tanzania in order to create enabling environments for the schoolchildren and other community members to adapt practices relevant for reducing the transmission of schistosomiasis. This paper describes the process of initiating the project. The school activities started in 2002 by screening all schoolchildren (n=1146) in the two schools for schistosomiasis and intestinal helminths and treating those infected. This was interspersed with school essay writing, video recorded dramas and household sanitation observations. The first activities made the researchers realise that they had to focus more on the teachers and change their perspective from one of "helping the research team with their project" to become full partners in the research process. Preliminary results are the actions taken by the teachers to develop a curriculum for enhanced schistosomiasis education in primary schools, making household sanitation surveys part of school activities, better links between the school and the community, and actions taken by community members to create safe swimming places. The experiences and lessons learned so far are discussed.
