Established in June 1995, Idaho ATSA is a state chapter of the Association for the Treatment and Prevention of Sexual Abuse (ATSA). 

The core values that guide ATSA are professional excellence, community safety, collaboration, and advocacy. ATSA promotes the philosophy that empirically based assessment, practice, management, and policies enhance community safety, reduce sexual recidivism, protect victims and vulnerable populations, transform the lives of those caught in the web of sexual violence, and illuminate paths to prevent sexual abuse. 

Idaho ATSA is a voluntary, multi-disciplinary membership organization focused specifically on the treatment and prevention of sexual abuse. IATSA members are dedicated to community safety and endorse evidence based treatment practices and management policies.
