SAMHSA'S CAPT relies on the experience and expertise of multiple stakeholders to identify and shape the design and delivery of CAPT training and technical assistance protocols, products, and services. Among these stakeholders are the CAPT Regional Technical Expert Panels (RTEPs), located in each of SAMHSA's CAPT's five service areas. The RTEP includes Single State Authority and National Prevention Network leaders from each of the 50 States, as well as prevention leaders from the Jurisdictions and Tribal entities that the SAMHSA's CAPT serves. These groups help guide service delivery by providing insight into emerging needs and systemic capacity, critical feedback on what is and is not working, and suggestions for customizing services to meet audience needs.
