Sexual violence is considered a serious problem due to its keep-increasing cases. Schools play very important role in preventing sexual violence by providing educational services based on gender equality through school management standard. This study evaluates the implementation of management standard of gender-responsive school and the challenges to preventing sexual violence. Four senior high schools in Sragen Regency Indonesia were selected. The quantitative data were collected from a survey to 198 respondents comprising principals, teachers and students. The qualitative data were obtained from focus group discussions. The quantitative data were analyzed using percentage, whilst the qualitative data were analyzed using interactive-model analysis of Miles and Huberman. The findings show that the majority of the respondents (96.5%) stated that school management standard had been gender-responsive. Nevertheless, the schools did not have sufficient facilities and infrastructures which could prevent sexual violence. The challenges to preventing sexual violence are the schools' willingness to build critical awareness of all students, teachers, employees and parents by formulating their vision, mission and strategy based on gender equality values, developing the principles of conduct and integrating sexual violence issue into the schools' academic and non-academic activities.
