Developed by Advocates for Youth, UNESCO, and UNFPA, this resource supports pre-service training of teachers for the delivery of school-based sexuality education in East and Southern Africa. Its objective is to equips teachers with the basic knowledge and skills necessary to deliver effective sexuality education in the classroom. Pre-tested in Uganda and through a regional workshop held in South Africa, the module includes nine core sessions lasting approximately thirty-eight hours, requiring a total of forty-two hours in its totality. Key topic areas include adolescent sexual and reproductive health in East and Southern Africa, an overview of sexuality education, adolescent development, experiential learning and facilitation skills, classroom management, application of skills through simulation of lesson plan delivery, and policy and ethical considerations. While the material is focused on training teachers for school-based sexuality education, the material can be adapted to out-of-school environments.
