Exam Format at a Glance
The January 2026 handbook confirms the CARN-AP exam is a closed-book, 150-question multiple-choice test, delivered in a four-hour window. Roughly 25 of those questions are unscored pilot items used to validate future exam content - you won't know which ones, so treat every question as scored. No calculator is required, which tells you the exam leans on clinical judgment and pharmacologic reasoning rather than computation.
Registration opens a 90-day eligibility window once your application is approved, and testing itself is offered year-round rather than in fixed windows. That flexibility is worth understanding fully before you schedule - see CARN-AP Exam Dates 2026: Testing Windows, Deadlines & Scheduling for how the 90-day clock actually plays out.
Key Takeaway
Because roughly one in six questions is an unscored pilot item, never let a single strange or unfamiliar question derail your pacing - it may not even count toward your score.
The Five Domains, Weighted
The 2026-implemented blueprint (updated in 2025) organizes exam content into five activity domains. Two of them are jointly the largest, which should directly shape how you allocate review time.
Domain 1: Assess & Diagnose (30%)
Covers comprehensive addictions assessment, differential diagnosis, and clinical formulation for advanced-practice addictions care.
- Screening and diagnostic criteria across substance use disorders
- Co-occurring psychiatric and medical conditions
Domain 2: Prescribe/Intervene (30%)
Covers pharmacologic management, medication-assisted treatment protocols, and intervention selection.
- Medication initiation, titration, and monitoring
- Evidence-based intervention selection by clinical scenario
Domain 3: Educate (25%)
Covers patient, family, and interprofessional education around addictions treatment and recovery.
- Health literacy-appropriate patient teaching
- Educating other providers and care teams
Domain 4: Consult (10%)
Covers collaborative and consultative advanced-practice functions across care settings.
- Interdisciplinary consultation scenarios
- Referral and care-coordination decisions
Domain 5: Research, Ethics, & CQI (5%)
Covers research application, ethical decision-making, and continuous quality improvement.
- Applying evidence to practice
- Ethical frameworks in addictions care
For a full breakdown of subtopics and sample question angles inside each of these five areas, see CARN-AP Exam Domains 2026: Complete Guide to All 5 Content Areas.
Patient-Problem Content Axis
Separate from the five activity domains, the blueprint also organizes content by patient problem. Opioid use disorder and alcohol use disorder each account for 24% of this axis - meaning nearly half of the exam's clinical content, when viewed through this lens, concentrates on just these two substance categories.
Eligibility Checklist
Eligibility for CARN-AP is layered, and missing a single hour requirement can delay your application. Confirm each item below against your own documentation before submitting.
- Current, unencumbered RN license meeting ANCB licensure rules
- Master's degree or higher in nursing
- 500 supervised advanced-practice addictions direct-patient-contact hours within four years
- An additional 1,500 advanced-practice addictions hours within three years
- 45 continuing-education contact hours within three years, with at least 51% addictions-specific
- Supervisor verification of hours (with an application exception available for qualifying independently practicing NPs)
Every one of these requirements is explained in granular detail, including documentation tips, in CARN-AP Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Fees & Registration Mechanics
The exam fee is $350 if you belong to ASAN, IntNSA USA, or NOVA, and $400 for standard applicants. Once approved, you have a 90-day eligibility window to schedule and sit for the exam through PSI. There's no fixed testing season - appointments are available year-round, so plan your window around your own study schedule rather than a registration deadline.
Key Takeaway
Joining ASAN, IntNSA USA, or NOVA before you apply can reduce your exam fee from $400 to $350 - check membership timing before you pay.

Renewal & Recertification
CARN-AP certification is valid for four years. To renew, you need an active RN license, 1,200 advanced-practice addictions hours accrued during the certification cycle, and 80 renewal points - with at least 51% of those points addictions-specific. Recertification by examination remains an alternative path if you prefer testing over point accumulation.
- Renewal fee: $325 for eligible association members
- Renewal fee: $375 standard
Because the passing standard and renewal math both hinge on precise thresholds, review CARN-AP Passing Score 2026: Exactly What You Need to Pass so you understand exactly what 77% means in practice on exam day.
One-Week Cheat Sheet Review Plan
If you already completed a full study cycle and just need a final-week structured pass through this cheat sheet, allocate days by domain weight rather than evenly - heavier domains earn more review time.
Assess & Diagnose + Prescribe/Intervene
- Drill diagnostic criteria and MAT protocols since these two domains total 60% combined
- Cross-reference opioid and alcohol use disorder scenarios specifically
Educate
- Practice patient and interprofessional teaching scenarios
Consult + Research, Ethics, & CQI
- Review consultation triggers and ethical decision frameworks - lower weight, but easy points if reviewed
Timed Practice
- Simulate the four-hour, 150-question format under closed-book conditions
