Addiction Resource Score
Scoring is assigned by a proprietary system which helps surface key metrics that determine quality. The 10-point scale factors in categories such as operations, customer satisfaction, and trust metrics.
We understand that choosing an addiction treatment center can be overwhelming, especially with so many options, promises, and marketing messages. That's why we've developed a clear, standardized rating system designed to cut through the noise and highlight what truly matters: safety, quality of care, and transparency. Our goal is to give individuals and families the information they need to make confident, informed decisions during a critical time.
In this guide, we explain exactly how we rate treatment centers—from accreditation and staff credentials to therapy options, facility environment, and family involvement. You'll see how we assign scores, award badges, and update listings to ensure accuracy and fairness. Most importantly, our system focuses on elevating centers that prioritize ethical, evidence-based care, not just those with the best marketing. This way, you can trust that the ratings you see reflect meaningful standards that help you find the right fit for lasting recovery.
