CSA, the partner organisation of Rutgers in Kenya, is license holder and the main implementer of the WSWM programme in Kenya, since 2006. CSA has built up a wealth of experiences in all aspects of the programme: the adaptation of the WSWM curriculum to the Kenyan context, establishment of an advisory board, coordination with the ministry of education for selection of schools and follow up, teacher training and guidance to the schools. Despite positive appreciation by teachers and students, the reach in number of students remained too low and hence cost per student was too high. Acknowledging that there was still high demand for comprehensive sexuality education for youth in Kenya despite positive developments during the past 10 to 15 years, the WSWM programme was considered to be eligible for scaling up. The Scaling Up trajectory aims at developing strategies to increase the number of students reached with little cost per student, that in return will increase the scaling up capacity of the programme. 4 schools were selected for pilot since 2013 to 2015, three years project.
