This article shows how the dialogic approach adopted by some schools in Spain generates a shift in approaches to gender violence, an issue still not explored in the literature. The shift is from an approach determined mainly by female experts to a dialogic one in which all women, including teachers, mothers, students, sisters, stepsisters, friends, and volunteers, are involved in designing and implementing programmes to prevent gender violence. An analysis of data obtained from six primary schools in Spain shows how the voices of all women are relevant to identify situations of gender violence that girl pupils are experiencing, as well as in the design of school-based processes to prevent violence that affects these girls.
