CARN Exam Dates 2026: Testing Windows, Deadlines & Scheduling

How CARN Testing Windows Actually Work in 2026

Unlike certification exams that open only during set testing periods each year, the Certified Addictions Registered Nurse (CARN) exam does not follow a seasonal calendar. The Addictions Nursing Certification Board (ANCB) - the body that governs CARN - keeps the exam open for scheduling throughout the year. There is no "spring window" or "fall window" to circle on your calendar. Instead, the clock that matters is the one that starts the moment your application is approved.

This is a meaningfully different structure than many nursing specialty exams, and it changes how you should plan. Rather than aligning your study schedule to an external testing period, you control the timeline almost entirely: when you apply, when you get approved, and when within your 90-day window you actually sit for the test.

Application Timeline: From C-NET Submission to Test Day

C-NET processes CARN applications and manages the overall testing logistics on behalf of ANCB, while PSI is the vendor that actually delivers the computer-based exam at testing centers. Understanding this split matters for scheduling purposes: your eligibility review happens through C-NET, but your actual seat reservation happens through PSI once you're cleared.

The practical sequence looks like this:

1. Submit your application and documentation to C-NET. This includes proof of your current qualifying RN license, verification of at least 2,000 hours of addictions-related RN practice within the preceding three years, and documentation of 30 continuing-education hours within that same three-year window, with at least 51% specific to addictions nursing.
2. Pay the exam fee. The standard fee is $300; it drops to $250 if you hold a qualifying membership with ASAN, IntNSA USA, or NOVA.
3. Receive approval and your 90-day testing window. Once C-NET confirms you meet eligibility requirements, you are authorized to schedule your exam with PSI at any point within the next 90 days.
4. Schedule and sit for the exam. You choose the specific date and PSI location within that window.

If you're still assembling documentation for hours or continuing education, it's worth reviewing the full breakdown in CARN Requirements 2026: Eligibility, Prerequisites & How to Qualify before you submit anything, since incomplete applications simply delay the start of your 90-day clock.

Scheduling Your Exam with PSI

Once approved, you'll book your seat through PSI, the vendor delivering the actual 150-question, three-hour CARN exam. Because testing is available year-round, availability is generally driven by local seat capacity rather than a national bottleneck around a single date. That said, popular locations and popular days of the week (often near the start or end of a month) can fill faster, so it pays to check availability early in your 90-day window rather than waiting until the final weeks.

A few scheduling realities to plan around:

• Your 90 days include weekends and holidays - the window does not pause or extend for either.
• Rescheduling within the window is typically possible but should be done as early as possible if your first-choice date isn't available.
• If you fail to test within the 90-day window, you will generally need to reapply and pay applicable fees again - so treat the window as firm.

Deadlines and Documentation Checklist

Because there's no external testing calendar to track, the deadlines that matter for CARN are entirely self-generated. Missing them costs you time and, in some cases, money. Before you submit your application, confirm you have:

• Verification of a current, unencumbered, qualifying RN license
• Documentation covering at least 2,000 hours of addictions-related RN practice within the preceding three years
• Records for 30 continuing-education hours completed within the preceding three years, with at least 51% specific to addictions nursing content
• Payment ready for the $300 fee (or $250 with a qualifying ASAN, IntNSA USA, or NOVA membership)

If any of these are incomplete, resolve them before applying - a rejected or paused application wastes time you'd rather spend studying inside your eventual 90-day window.

Test Day Logistics and Rules

On exam day, you'll sit for 150 multiple-choice questions in a three-hour window, delivered on computer at a PSI test center. A detail many candidates overlook: roughly 25 of those 150 items are unscored pilot questions used by ANCB to evaluate future exam content. You won't know which items are pilot questions and which are scored, so the only sound strategy is to treat every question as if it counts.

The passing standard is 75%, and ANCB reported a 70% CARN pass rate for 2025 - useful context for calibrating how seriously to take your prep timeline. For a full breakdown of what the passing score actually means in practice, read CARN Passing Score 2026: Exactly What You Need to Pass, and for a broader look at difficulty relative to other nursing certifications, see How Hard Is the CARN Exam? Complete Difficulty Guide 2026.

Materials rules are strict and worth internalizing before test day, not during check-in:

• No books, notes, or personal reference materials of any kind
• No personal calculators - if any calculation is needed, it will be provided digitally on-screen
• Results are delivered immediately upon completion, so you'll leave the center already knowing your outcome

Timing Your Prep Around the 90-Day Window

The 90-day testing window is really a study-planning gift: it gives you a fixed, self-selected runway to prepare against the exam's actual content distribution. The 2025 role-delineation blueprint, implemented in 2026, weights the five domains unevenly, and your study time should mirror that weighting rather than being spread evenly across all five.

Domains 1, 3, and 4 - biopsychosocial assessment, individualized care planning, and behavioral-change education - each carry 15% weight and round out the remaining half of the exam. A full breakdown of every domain, with subtopics and study emphasis, is available in CARN Exam Domains 2026: Complete Guide to All 5 Content Areas.

Because opioid use disorder (27%) and alcohol use disorders (25%) together make up 52% of the patient-problem distribution tested across all domains, these two substance categories deserve disproportionate attention regardless of which domain a given question falls under.

Note that spacing your review this way isn't generic advice for its own sake - it's built directly around CARN's blueprint weighting, so the weeks with the most study hours match the domains worth the most points. For structured question banks that mirror this domain distribution, CARN Study Guide 2026: How to Pass on Your First Attempt and practice sessions on the main CARN practice test site are useful anchors for the later weeks of this plan.

After You Pass: Renewal Timing

CARN certification is valid for four years, and the renewal clock starts the moment you're certified - not on some fixed annual cycle. Renewal requires 2,000 hours of addictions-nursing practice and 60 continuing-education hours accumulated during the four-year cycle, with at least 51% of those CE hours addictions-specific. Renewal costs $275, or $225 for qualifying members.

Because your renewal deadline is tied to your original certification date rather than a calendar year, it's worth marking it immediately after you pass - ideally in the same place you track other professional license renewals. Waiting until close to the four-year mark to start counting hours and CE credits is a common and avoidable mistake.
