The Gender Equity Movement in Schools (GEMS) program aims to promote gender equality among adolescents in school settings by encouraging equal relationships between girls and boys, examining the social norms that define men’s and women’s roles, and questioning the use of violence. The main components of GEMS are group education activities (GEA) and a campaign. The campaign is a week-long series of events, including games, competitions, debates and short plays, aimed at reaching out to students. This campaign guide walks facilitators through steps and ideas to organize similar campaigns on gender and violence in schools.
