Over the past two decades, comprehensive sexuality education has increasingly been recognised as a measure that positively impacts on the sexual behaviour of young people in Africa. Despite this, and a political call to scale-up the use of comprehensive sexuality education in schools in South Africa, learners with disabilities continue to be left behind. Besides contending with negative hegemonic constructs of disabled sexualities, educators of learners with disabilities lack skills and resources to teach sexuality in accessible formats. Based on this premise, a comprehensive sexuality education approach--Breaking the Silence--was developed and piloted to assist educators of learners with disabilities to provide access to comprehensive sexuality education in KwaZulu-Natal, South Africa. This article presents results from the formative evaluation of this pilot work and discusses educators' perceptions of their learners with intellectual disabilities' sexual knowledge, agency and behaviour after implementing the approach. Although educators appeared to situate learners with intellectual disabilities as sexual agents, their implementation of the approach was dependent on the cognitive ability of learners, and discourses of culture, gender and protection from violence.
