0.1 NCAC Exam Structure, Eligibility, and Scoring

The National Certified Addiction Counselor (NCAC) credentials are awarded by the National Certification Commission for Addiction Professionals (NCC AP), the independent credentialing body of NAADAC, the Association for Addiction Professionals. NCC AP describes the NCAC I and NCAC II as voluntary national and international certifications for professionals working in substance use disorder (SUD) and addiction-related disciplines who want to document skills gained through years of supervised work experience.

Addiction counseling draws on psychopharmacology, clinical assessment, diagnosis under the DSM-5, evidence-based psychotherapies, federal confidentiality law (42 CFR Part 2 and HIPAA), and the NAADAC/NCC AP Code of Ethics. The examination samples all of it. Before studying the content, get the mechanics right — a surprising amount of what circulates online about this exam is wrong.

[!IMPORTANT] What NCC AP actually publishes — and what it does not. NCC AP publishes the item count (150), the testing time (three hours), the domain weights, and a fixed cut score of 67 percent (100/150). It does not publish a scored-versus-pretest item split, a scaled-score conversion, an Angoff cut-score narrative, a domain-level diagnostic score report, or a mandatory waiting period between attempts. Several commercial prep sites assert all of those, and some still describe a 200-question, four-hour exam. Treat the NAADAC/NCC AP credential pages as the controlling source.

1. Credentialing Architecture & the NCC AP Career Ladder

The three general addiction-counselor credentials form a ladder defined by academic degree and addiction-specific education. Note the detail that trips up most candidates: the supervised experience requirement is the same at all three levels — three years full-time or 6,000 hours — and every level requires a current state credential or license that is not an associate, provisional, intern, or trainee credential.

Contact-hour composition (all three levels). The contact hours must include at least six hours of ethics education/training and at least six hours of HIV/other pathogens education/training, and both must have been completed within the last six years. NCC AP does not publish additional mandatory sub-quotas (for example, a fixed number of pharmacology or co-occurring-disorder hours); anything beyond the ethics and HIV/pathogens minimums is set by the applicant's own state board.

[!NOTE] State licensure versus national credentialing. State boards (CADC, LCDC, LCAS, CASAC, LADC, and others) control the legal scope of practice. Many of them use the NCC AP examinations as their licensure test. If you are testing for a state credential, your state board approves you and issues the registration code; if you are testing for an NCC AP national credential, NCC AP approves your application first and then emails you the code and link. Registering without the required approval means you will not be permitted to test and your fee will not be refunded.

2. Exam Format, Delivery, and Test-Day Logistics

Fees you will actually pay

Rescheduling and cancellation. You may reschedule through the testing website at any time before the appointment; inside 72 hours the $90 reseating fee applies. You may cancel up to 72 hours before the appointment and generally receive a refund of the testing fee, though state board refund policies vary. Miss the appointment and you are charged in full with no refund.

3. Domain Weights: NCAC I, NCAC II, and MAC

All three examinations draw from the same five domains. Only the weights move, and they move very little — which is why a single study plan serves all three, with emphasis shifted by level.

How to read the differences. Moving from NCAC I to NCAC II shifts two percentage points from Ongoing Treatment Planning & Implementation into Addiction Counseling Practices & Skills — the level-two candidate is expected to do more of the direct clinical work. The MAC shifts weight out of Orientation and into Professional Practices, consistent with a master's-level role carrying more supervisory, ethical, and systems responsibility.

The nine skill groups NCC AP names

Underneath the five weighted domains, NCC AP lists the skill groups an applicant "should be well versed in." Use this list as a coverage checklist for your study plan:

1. Treatment admission (screening, intake, and orientation)
2. Clinical assessment
3. Ongoing treatment planning
4. Counseling services (individual, group, family, crisis intervention, and client education)
5. Documentation
6. Case management
7. Discharge and continuing care
8. Legal, ethical, and professional growth issues
9. Physiology and psychopharmacology

Skill groups 5 and 9 are the ones candidates most often neglect. Documentation and psychopharmacology are not "extra credit" here — they are named test content.

4. Renewal and Continuing Education

The NCAC credentials renew on a two-year cycle. Renewal requires:

• Evidence of a current state-issued credential/license (again, not an associate, provisional, intern, or trainee credential);
• 40 hours of continuing education completed in the two years since the credential started;
• Work history for the two years prior to renewal;
• A signed statement that you have read and adhere to the NAADAC/NCC AP Code of Ethics; and
• The $200 non-refundable renewal fee.

5. Retake Policy and Testing Accommodations

Retakes

• Three attempts per calendar year. You may take an NCC AP examination up to three times in a calendar year. If you fail three times, NCC AP requires you to wait until the next year before testing again.
• NCC AP publishes no fixed waiting period between attempts inside that year. Claims of a mandatory 90-day cooling-off period come from third-party prep sites, not from NCC AP.
• Re-registration path follows the original path. If you failed an exam required by your state board, contact the state board to register again; if you failed an exam for an NCC AP national credential, contact NCC AP. The cost of re-testing is the same as the original.

Accommodations under the ADA

• Candidates with documented disabilities may request accommodations by completing NCC AP's special accommodations request form and returning it by mail, email, or fax, with a physician's note or other documentation explaining the need.
• The form must be received 35 calendar days before the requested testing date.
• You cannot register online for an accommodated examination — an NCC AP representative registers you.

Technical problems during the exam

If you test onsite, ask the proctor. If you test by distance proctoring, use Kryterion's support chat, which is staffed 24/7. Knowing this in advance prevents a solvable technical issue from turning into a lost attempt.
