1.1 CARN Exam Overview, Eligibility & Requirements

1.1 CARN Exam Overview, Eligibility & Requirements

The Certified Addictions Registered Nurse (CARN) credential represents the gold standard in board certification for registered nurses specializing in substance use disorders (SUD) and addictive behaviors. Governed by the Addictions Nursing Certification Board (ANCB) — founded in 1989 by the International Nurses Society on Addictions (IntNSA) and autonomous since 2014 — CARN certification validates advanced specialty knowledge, expert clinical judgment, and adherence to evidence-based nursing standards. Examination development and administration are conducted by the Center for Nursing Education and Testing (C-NET). Achieving CARN certification signifies verified mastery across acute withdrawal management, chronic disease management, harm reduction, pharmacotherapy, dual-diagnosis care, and ethical advocacy.

Eligibility Criteria & Mandatory Requirements

To ensure that certificants possess both foundational nursing competence and dedicated clinical experience, the ANCB enforces three core eligibility requirements that must all be satisfied prior to sitting for the examination:

1. Current RN Licensure: Candidates must hold a current, full, and unrestricted registered nurse license — earned by passing the NCLEX or verified for equivalency by the Commission on Graduates of Foreign Nursing Schools (CGFNS), World Education Services (WES), or Educational Records Evaluation Services (ERES). Nurses licensed in more than one jurisdiction must hold full and unrestricted licenses in every jurisdiction where they are licensed.
2. Specialty Practice Hours: Candidates must attest to a minimum of 2,000 hours (one year) of addictions-related nursing practice within the three years immediately preceding application. Eligible roles span staff nursing, administration, teaching, private practice, consultation, counseling, or research.
3. Continuing Education (CE) Contact Hours: Candidates must complete 30 contact hours of continuing education within the preceding three years. At least 51% (minimum 16 hours) must be specific to addictions nursing; the remainder may cover related topics such as HIV/AIDS, hepatitis, or pain management. Certificates are not uploaded with the application but must be produced on request.

Eligibility Parameter Summary

Alternative-to-Discipline Policy: Nurses in recovery are welcomed. A surrendered license or monitoring-agreement violation makes an applicant ineligible; a nurse with a restricted license in a monitoring program must submit a program letter confirming an active license, compliance, and program support for testing.

Exam Format, Technical Structure & Scoring

The CARN examination is a standardized, computer-based assessment testing clinical reasoning and decision-making rather than rote recall.

• Total Question Count: 150 multiple-choice questions.
• Scored vs. Unscored Items: Of the 150 items, about 25 are unscored pilot (experimental) questions being validated for future test forms; the remaining ~125 items are scored. Pilot items are indistinguishable from scored items, so answer all 150 with equal diligence.
• Time Allocation: 3 hours (180 minutes) of testing time, averaging 1.2 minutes (72 seconds) per question. There is no penalty for guessing.
• Passing Standard: Candidates must answer 75% of test items correctly. The standard is set by a panel of addictions nursing experts using the criterion-referenced Angoff procedure — candidates are measured against a predetermined standard, not against other test takers.
• Results: Scores are available immediately at the testing facility as a total percentage correct. Non-passing candidates also receive sub-scores for each major content area to guide remediation; passing candidates receive only the total score.
• Retakes: C-NET emails an automated retake scheduling link no sooner than 30 days after the last attempt (usable once; reissued after each unsuccessful attempt for up to one year from the original application date).
• Fees: $300 standard; $250 with proof of membership in ASAN, IntNSA USA, or NOVA attached to the application. Applications are online-only (paper applications ended November 1, 2025); approved candidates receive a 90-day testing window to schedule and sit at a PSI testing location.

Content Domains & Blueprint Breakdown (Official ANCB Blueprint)

The current ANCB test blueprint — published by C-NET and implemented for the 2026 exam cycle — is a two-dimensional matrix crossing patient problems (substance classes and co-occurring conditions) with domains of practice (addictions nursing activities). Every exam item tests one patient problem through one practice activity.

Patient Problem Rows (% of 150 Items)

Domain-of-Practice Columns (% of 150 Items)

How This Guide Maps to the Matrix

• Chapters 2 and 4 teach assessment and acute care across all substance classes (practice domains 1–2).
• Chapter 3 covers individualized planning (domain 3): ASAM criteria, motivational interviewing, trauma-informed care, family work, and nursing-process care planning.
• Chapter 4 and Chapter 5 cover treatment and management for every patient-problem row — alcohol, opioids, stimulants, sedatives/gabapentinoids, cannabinoids/hallucinogens, and tobacco — including withdrawal, MOUD/MAUD, harm reduction, and pain management (domains 2 and 5).
• Chapter 5 also delivers domain 4: prevention, SBIRT brief intervention, patient education, and behavioral addictions.
• Chapter 6 addresses the recovery continuum (domain 5): relapse prevention, mutual-help, recovery capital, and transitions of care.
• Chapter 7 covers professional role, ethics, and legal content that the blueprint embeds across all domains (42 CFR Part 2, scope and standards, stigma).

Application Process & Recertification Lifecycle

1. Online Application: Apply through the C-NET website (Addictions Nursing section), paying via PayPal and uploading a government-issued photo ID whose name exactly matches the application.
2. Processing & Permit: Standard processing takes about two weeks. Approved candidates are registered with C-NET's testing partner PSI, receive an examination permit by email, and must schedule and test within a 90-day window at a PSI testing location.
3. Four-Year Recertification: CARN certification is valid for 4 years with a current RN license. Recertify by documenting 60 CE contact hours (at least 51% addictions-specific) plus 2,000 hours of addictions-related practice during the certification period — or by passing the current CARN examination. A 3-month post-expiration grace period (with late fee) precedes full lapse.
