All children have the right to safe and quality education, regardless of their sexual orientation, gender identity/expression or sex characteristics. In the last decade, national education sectors in most Council of Europe member States started or continued responding to violence based on sexual orientation, gender identity/expression or sex characteristics (SOGIESC-based violence). This report provides an overview of this violence in European schools, explores how member States seek to prevent or address it, and makes recommendations to national education sectors to better do so.
