School-related gender-based violence (SRGBV) is one of the worst manifestations of gender discrimination and violates a wide range of children's rights. Education is critical in empowering and transforming the lives of young people, especially girls, yet widespread gender-based violence (GBV) in and around schools seriously undermines the achievement of high-quality, inclusive, and equitable education for all children. The prevalence of multiple types of violence against children, both within and outside Kenyan schools, continues to be a major concern. The 2019 Kenya Violence Against Children Survey (VACS) found that 49 percent of girls and 48 percent of boys aged 13-17 years had experienced physical violence, and 11 percent of girls and 4 percent of boys indicated that they had experienced sexual violence. This Kenya country study is part of a larger, four-country study of SRGBV that includes Jamaica (ED610693), Kenya, Malawi (ED614033), and Nigeria (ED610741). The study was informed by the GBV situation globally as well as in the study countries specifically. The Kenya country study systematically documents the voices of girls and boys in primary schools to establish the prevalence of and possible factors leading to SRGBV, determines country response options to challenges, and identifies possible interventions toward minimizing SRGBV. The study design was descriptive and explanatory in nature, using a sample of 638 students in primary schools (grades 4-8) and 117 teachers from 4 of the 47 counties in Kenya using the Krejcie and Morgan (1970) sampling technique. Data were collected using desk review, survey, focus group discussion, and mapping exercises conducted with students. The results of this study show the magnitude and forms of prevalence of SRGBV among primary school students as well as the students' emotional expressions of these experiences--causing girls and also boys aged 10-13 years to be afraid to report or share GBV challenges because the abusers are their family members, teachers, neighbors, and friends.
