The Our Rights, Our Lives, Our Future (O3) programme supports delivery of good quality comprehensive sexuality education (CSE) that empowers adolescents and young people (AYP) and builds agency, while developing the skills, knowledge, attitudes, and competencies required for preventing HIV, reducing early and unintended pregnancies (EUPs), and eliminating gender-based violence (GBV). The objectives of the programme are to: 1) Secure and sustain strong political commitment and support for adolescents’ and young people’s (AYP’s) access to comprehensive sexuality education (CSE) and sexual and reproductive health (SRH) services across sub-Saharan Africa (SSA). 2) Support the delivery of accurate, rights-based, and good quality CSE programmes that provide knowledge, values, and skills essential for safer behaviours, reduced adolescent pregnancy, and gender equality. 3) Ensure that schools and community environments are safer, healthier, and inclusive for all young people. 4) Strengthen the evidence base on CSE and safer school environments.
