SEHER was an intervention by Sangath which aspired to create an enabling environment and promote healthy behaviour amongst school children. SEHER covered 74 government-run secondary and higher secondary schools in Bihar’s Nalanda district. SEHER promoted social skills amongst adolescents with the participation of the school community. SEHER also nourished relationships between teachers and parents and involved students in school-level decision-making processes to encourage their belongingness and connectedness to the school. This resulted in a decrease in cases of bullying, violence and depression, along with moderated improvements in students’ attitudes towards gender equity and knowledge related to reproductive and sexual health.
