The NADD Accreditation Program

Developed in association with The National Association of State Directors of Developmental Disabilities Services (NASDDDS) 

The NADD Accreditation Program was developed to improve the quality and effectiveness of services provided to individuals with a dual diagnosis through the development of competency-based professional standards and through promoting ongoing professional and program development.  NADD offers accreditation for programs serving individuals with a dual diagnosis, rather than the agency or organization that offers these programs. An organization with several different programs that serve individuals with a dual diagnosis may seek accreditation for each of these programs.  A NADD Accreditation demonstrates that the program has met the standards established by NADD.

An overview of the NADD Accreditation Program is available in the Executive Summary.  For greater detail, click on the NADD Accreditation Program Manual.
