The NADD Competency-Based Clinical Certification Program

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

NADD developed the NADD Competency-Based Clinical Certification Program  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 development.  Clinical certification through the NADD Competency-Based Certification Program validates and provides assurance to people receiving services, professional colleagues, employers, and third-party payers that a clinician has met the standards established by NADD for providing services to individuals with ID/MI.  Certification attests to the clinician's competency in providing these services.  Clinicians who receive NADD clinical certification will be entitled to use "NADD-CC" as a credential.  (The "CC" stands for "certified clinician.")

An overview of the NADD Competency-Based Clinical Certification Program is available in the Executive Summary.  For greater detail, click on the NADD Competency-Based Clinical Certification Program Online Manual.
