This toolkit was developed by and for advocates in the runaway and homeless youth (RHY) and domestic and sexual assault (DV/SA) fields to help programs better address relationship violence with runaway and homeless youth. The Toolkit organizes information, resources, tips and tools drawn from the lessons learned by collaborative projects funded by the Family and Youth Services Bureau (FYSB) that brought together domestic violence programs and runaway and homeless youth agencies to address relationship violence among street youth.
