A Certified Peer Support Specialist (CPSS or PSS) is a person with lived experience of mental health or substance use challenges who is trained and certified to support others in their recovery. Peer support specialists use their personal recovery experience as a tool to help others navigate treatment, build community, and maintain wellness. Certification requirements vary significantly by state โ most require 40โ80 hours of training, a written exam, and documentation of personal lived experience. Peer support specialist positions are among the fastest-growing behavioral health roles, with demand driven by Medicaid coverage expansion for peer services.
Peer support specialists provide non-clinical support rooted in shared experience. Unlike therapists or case managers, PSS professionals draw on their own mental health, substance use, or trauma recovery journey as the basis for connection with the people they serve.
