As part of the CATALYST Consortium South-to-South programme, PROFAMILIA/Colombia and the Centre for Development and Population Activities (CEDPA) collaborated to produce a manual for managers of adolescent sexual and reproductive health programmes that builds on PROFAMILIA/Colombia experience in delivering adolescent sexual and reproductive health services and CEDPA's expertise in participatory methodologies and adult learning. Implemented through a five-and-a-half-day workshop, the manual builds the capacity of youth-serving programme managers and coordinators from the public and private sectors, with limited experience managing youth programmes, to design programmes that respond to the sexual and reproductive health (SRH) needs and rights of young people (10-24 years of age), and helps youth develop life skills and adopt healthy behaviors. The manual also strengthens programme managers' skills to advocate for adolescents.
