The focus of this technical assistance guide is to help sexual assault service providers build, expand, formalize, and maintain strong interagency responses to sexual violence. It includes a brief overview followed by Practice Tips, Ways to Build SART Excellence, and Key Resources. Sexual Assault Response Teams (SARTs) are coalitions of agencies that serve sexual assault victims. Core membership for SARTs typically includes victim advocates, law enforcement officers, forensic medical examiners, forensic scientists, and prosecutors. Multidisciplinary SARTs work together to formalize interagency guidelines that prioritize victims needs, hold offenders accountable, and promote public safety. SART models range from informal, cooperative partnerships to more formalized, coordinated, and multidisciplinary responses on local, regional, state, tribal, or territory levels.
