Intra-family sexual abuse in childhood and adolescence is a serious problem with impactful negative consequences for mental health, and effective actions to combat it by the entire System for Guaranteeing the Rights of Children and Adolescents are important. In this sense, considering the school as a privileged place for children and adolescents to coexist and as one of the components of the SGDCA, it is important to reflect on its role in combating this type of violence. This research aims to understand the perceptions of adolescent students regarding the school and the possibilities of its action in combating sexual violence, more specifically intra-family abuse, both in terms of preventive work and in the measures adopted in the face of identification or suspected cases. Aiming for student participation, the research locus will be a municipal public school and the research subjects will be teenage girls, aged 12 to 15 years old. The research methodology will use the qualitative approach, which allows an approximation of the singularities of the perceptions of the subjects involved, and the narrative method. The data collection techniques used will be dialogue circles, semi-structured interviews, and collection of narratives written by the adolescents themselves (diaries).
