This report documents progress on implementation of a Swedish International Development Cooperation Agency (Sida)-funded UNESCO project that aims to strengthen sexuality education programmes for young people in school settings in Zambia. The project was conceptualized in line with the country’s thematic focus on broader economic and social development and is expected to reach all 9,000 government schools, 1,749,664 learners representing 100% of grades 5 to 12 learners, 40,000 in-service teachers, and 20,000 preservice teachers. The project’s overall purpose is to improve the sexual and reproductive health (SRH) outcomes of adolescents and young people (aged 10-24) in Zambia through increased access to high quality, age-appropriate and gender transformative SRH education and services.
