South Africa has a high prevalence of gender-based violence (GBV), with secondary school teachers playing a crucial role in fostering safe learning environments for students. This study employed semi-structured interviews with a purposive sample of 30 secondary school teachers from diverse geographical regions across South Africa. Interviews were audio-recorded and analysed using thematic analysis. Teachers reported increased awareness about GBV, but only 45% felt confident in implementing strategies to prevent GBV within their classrooms. Despite initial enthusiasm for the workshops, teachers identified significant gaps in knowledge and resources needed to implement effective GBV prevention measures effectively. Schools should provide ongoing support through professional development opportunities and resource allocation to ensure sustained impact of GBV prevention efforts.
