EXECUTIVE SUMMARY: Violence in schools and other educational settings is a worldwide problem. Students who are perceived not to conform to prevailing sexual and gender norms, including those who are lesbian, gay, bisexual or transgender (LGBT), are more vulnerable. Violence based on sexual orientation and gender identity/expression, also referred to as homophobic and transphobic violence, is a form of school-related gender-based violence. It includes physical, sexual and psychological violence and bullying and, like other forms of school-related violence, can occur in classes, playgrounds, toilets and changing rooms, on the way to and from school and online. This report presents the findings of a global review, commissioned by UNESCO, of homophobic and transphobic violence in schools and education sector responses.
