DSP Certifications

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

NADD developed the NADD Competency-Based IDD/MI Dual Diagnosis Direct Support Professional Certification Program to certify the competency of DSPs who support people with dual diagnosis.

DSP certification validates and provides assurance to individuals served, colleagues, and employers that a direct support professional has met the standards established by NADD for providing services to individuals with IDD/MI.

DSPs who receive NADD certification will be entitled to use “NADD-DSP” as a credential.

In general, DSPs spend more time with the person with IDD/MI than any other professional. The competence of the DSP can make a big difference in the quality of life for people. DSPs are often the ones charged with supporting skill building. They help the person engage in recommended therapies on a day-to-day basis.  This work requires an advanced level of skill and knowledge to do well.
