NCAC I and NCAC II Exams

This overview includes information to help you prepare for the National Certified Addiction Counselor, Level I (NCAC I) exam and the National Certified Addiction Counselor, Level II (NCAC II) exam. You’ll find details about eligibility, exam format, content areas, registration, costs, scoring, retakes, and study resources.

Exam Background and Purpose

The NCAC I and NCAC II credentials are national addiction counseling certifications offered through the National Certification Commission for Addiction Professionals (NCC AP), which is part of NAADAC, the Association for Addiction Professionals.

These credentials are intended for professionals working in Substance Use Disorders/Addiction-related disciplines. Candidates should review NCC AP, NAADAC, and state credentialing or licensing requirements before applying, because requirements can vary depending on the credentialing pathway and state board.

Eligibility

Eligibility requirements are set by NCC AP. Candidates generally need education and training in Substance Use Disorders/Addiction, supervised experience, and a current state-issued credential or license. The exact requirements differ for NCAC I and NCAC II.

Candidates should review the current NCAC I or NCAC II application instructions before applying. If you are testing for a state credential or license instead of a national NCC AP credential, contact your state certification or licensing board for approval and registration instructions.
