The purpose of credentialing is to standardize the quality of addiction prevention, intervention, treatment and continuing care services. Through standardized testing, the Commission is able to set a benchmark for professionals and monitor the abilities of those who treat addictions. Because the NCC AP is connected to the profession and to those who are using the credential on a day-to-day basis, the tests are evaluated annually to ensure they address the latest information on treating addictive disorders.

Specifically, national and international credentialing is important for addiction professionals:

  • to focus on the individual counselor and to provide a formal indicator of the current knowledge and competence at the national and international level;
  • to provide a national and international standard that exceeds most U.S. state requirements and encourages professionals to continue to learn for the sake of their clients;
  • to establish, measure, and monitor the requirements for knowledge in the profession; and
  • to provide assistance to employers, health care providers, educators, government entities, labor unions, other practitioners, and the public in the identification of quality counselors who have met the national and international competency standards.
