NCAC study guide
NCAC · Work through your exam, one topic at a time.
The NCAC I - National Certified Addiction Counselor, Level I - is a national credential for addiction counselors offered through NAADAC, the Association for Addiction Professionals. It is the entry tier of NAADAC's counselor certification ladder, aimed at counselors who are building supervised clinical experience in substance use disorder treatment and who want a nationally recognized, rather than state-only, mark of competence. The exam blueprint is organized into four domains: Understanding Addiction; Treatment Knowledge; Application to Practice; and Professional Readiness. Expect the questions to move from foundational material - how substance use disorders develop, how substances act, how assessment and screening work - into applied judgment, where you must choose the best counselor response in a clinical, ethical, or documentation scenario. The NCAC study guide has 4 sections and about 1,177 words.
01Understanding Addiction: Models, Diagnosis, and Etiology
Candidates must compare the moral, medical (disease), biopsychosocial, and learning/behavioral models of addiction. The disease model - chronic, progressive, relapsing, treatable, not a moral failing - underlies most treatment systems; the biopsychosocial model adds genetics, trauma, environment, and coping skills.

ASAM criteria place clients along a continuum - early intervention, outpatient, intensive outpatient, partial hospitalization, residential (clinically managed to medically monitored), and medically managed withdrawal management - using six dimensions: intoxication/withdrawal risk, biomedical conditions, cognitive/emotional status, readiness to change, relapse potential, and recovery environment. Detoxification is stabilization, not treatment.
280 words, about 1 min03Application to Practice: Screening, Planning, and Confidentiality
Screening is brief and identifies risk (AUDIT, CAGE, DAST-10, PHQ-9, SBIRT); it does not diagnose. Assessment is comprehensive and biopsychosocial (ASI domains), yielding a diagnosis and treatment plan.
295 words, about 1 min04Professional Readiness: Ethics, Boundaries, and Self-Care
Certified counselors are bound by a code of ethics (NAADAC) grounded in six principles: nonmaleficence, beneficence, autonomy, justice, fidelity, and veracity. Practice only within your scope; assess, refer, and document rather than improvise.
