- CRN exam fees are $325 for ARIN members and $425 for non-members in 2026.
- A $45 non-refundable late fee applies up to 14 days past the application deadline.
- Recertification costs the same $325/$425 structure every 4 years - no discount for repeat candidates.
- Eligibility requires 2,000 practice hours and 30 CE hours, which carry real time and money costs beyond the exam fee.
CRN Exam Fee Breakdown
The Certification Examination for Radiologic Nursing in Imaging, Interventional, and Therapeutic Environments - the official name behind the CRN credential - is administered by the Radiologic Nursing Certification Board (RNCB) and delivered through C-NET (Center for Nursing Education and Testing) at regional testing centers. Unlike some nursing specialty exams that bundle in study materials or retake vouchers, the CRN fee covers exactly one thing: a single seat for the computer-based test.
The exam itself consists of up to 150 multiple-choice objective questions administered over a 3-hour testing window. It's closed-book - no reference sheets, calculators, or electronic devices - so every dollar you spend on the fee is a dollar spent on a pass/fail attempt with zero built-in safety net. That reality alone makes preparation non-negotiable, which is why pairing your registration with a structured CRN study guide matters more than it might for exams with more forgiving retake policies.
ARIN Member vs. Non-Member Pricing
RNCB and the Association for Radiologic and Imaging Nursing (ARIN) are separate organizations, but ARIN membership directly affects what you pay for CRN certification. The pricing tiers are straightforward:
| Candidate Type | Exam Fee | Recertification Fee |
|---|---|---|
| ARIN Member | $325 | $325 |
| Non-Member | $425 | $425 |
| Late Application (either tier) | +$45 non-refundable | +$45 non-refundable |
The $100 gap between member and non-member pricing repeats at every recertification cycle, not just your first exam. If you plan to hold the CRN credential across multiple 4-year cycles, that gap compounds - making an ARIN membership worth comparing against its own annual dues before you register.
Key Takeaway
Calculate ARIN's annual membership dues against the $100 exam discount before deciding whether to join - the math often favors membership if you're recertifying more than once.
Late Fees and Deadline Mechanics
RNCB runs four testing windows per year - January, April, July, and October - each with a 30-day scheduling window per candidate. Applications close roughly one month before each window opens, which means procrastination has a direct financial consequence: a $45 non-refundable late fee, accepted up to 14 days past the deadline.
After that 14-day grace period closes, there's no further extension - you simply miss the window and wait for the next one. This is one of the most overlooked cost variables in CRN planning. Candidates who assume they can "register whenever" often discover the standard deadline has already passed and the only options are the late fee or a multi-month delay. Understanding the full scheduling mechanics - covered in depth in our CRN exam dates and testing windows guide - is essentially free insurance against this avoidable $45 charge.
Hidden Costs Behind the Eligibility Requirements
The $325-$425 exam fee is the headline number, but it isn't the full financial picture. CRN eligibility requires:
- A current, active RN license (or international equivalent) - renewal fees vary by state but are an ongoing cost of eligibility.
- A minimum of 2,000 hours of radiology nursing practice within the past 3 years, verified by two responsible practitioners in the specialty (one in a supervisory role).
- 30 contact hours of continuing education applicable to radiology nursing within 24 months of the exam date, with at least 15 hours specific to radiology nursing.
That CE requirement is where real out-of-pocket cost often hides. Depending on your employer's tuition support, CE hours can range from free (employer-sponsored in-services) to several hundred dollars if you're sourcing radiology-nursing-specific content independently. Before budgeting for the exam fee alone, review the full breakdown in our CRN requirements and eligibility guide so you know exactly what documentation and verification steps to plan for - and pay for - in advance.
Practice Hour Verification
Two practitioners must attest to your 2,000 hours, and one must hold a supervisory position. Line this up early - chasing down signatures during a late application window adds stress on top of the $45 late fee.
- Confirm your supervisor's willingness to verify hours before you submit
- Keep a running log of radiology-specific practice hours rather than reconstructing them at deadline time
Recertification Cost Every 4 Years
CRN certification is valid for 4 years, and maintaining it costs the same as earning it the first time: $325 for ARIN members and $425 for non-members if you choose the re-examination route. Alternatively, you can maintain certification through 60 contact hours within the 4-year cycle (minimum 30 radiology-nursing-specific), combined with an active RN license, 2,000 hours of radiology nursing practice within the past 4 years, and current practice averaging 8 hours per week.
Notably, the CE-based maintenance pathway doesn't eliminate the fee - the $325/$425 recertification fee applies regardless of which pathway you choose. This means CRN is a recurring line item in your professional development budget, not a one-time purchase.
| Maintenance Pathway | Requirement | Fee |
|---|---|---|
| Re-examination | Retake the CRN exam | $325 / $425 |
| CE-based renewal | 60 contact hours (30 radiology-specific min.), active hours, practice hours | $325 / $425 |
Total Cost of Ownership: First Attempt Through Recert
Adding it up over an 8-year span (two certification cycles) for an ARIN member who passes on the first attempt and renews via CE:
- Initial exam fee: $325
- Recertification (Year 4): $325
- CE hours across both cycles: variable, employer support-dependent
- Potential late fees: $45 each, entirely avoidable with early registration
Non-members face the same structure at $425 per cycle. Either way, the largest controllable variable isn't the RNCB fee schedule - it's whether you pass on your first attempt or need to register (and pay) again. That's the single biggest reason a focused prep strategy pays for itself: avoiding a second $325-$425 charge is far cheaper than any study resource you'll buy. For a realistic read on how challenging the exam actually is before you commit funds, see how hard the CRN exam really is and review documented outcomes in our CRN pass rate analysis.
Cost vs. Value: Is the Spend Justified?
Whether $325-$425 (plus CE costs) is "worth it" depends heavily on your employment context. Facilities hiring for interventional radiology suites, CT/MRI-heavy imaging departments, and vascular access teams often list CRN as preferred or required for senior radiology nursing roles. If your department reimburses certification fees - many do, as part of professional development budgets - the net cost to you may be minimal.
Before committing funds, it's worth reading a dedicated cost-benefit analysis. Our CRN certification ROI analysis and CRN salary guide walk through how certification interacts with career advancement and job postings for CRN jobs without relying on invented salary claims - grounding the decision in what employers actually ask for.
Budgeting Your Study Time Around the Fee Windows
Because RNCB only offers four testing windows a year and each carries a real financial penalty for a missed deadline or a failed attempt, your study schedule should be built backward from the application deadline - not the test date. A simple way to allocate your remaining weeks before a window closes is to weight time by domain and modality significance, since not all content is tested equally.
The exam blueprint weights five practice domains: Assess patient and plan care (25%), Administer, monitor, and evaluate therapeutic interventions (25%), Teach patient and family/Provide a supportive environment (17%), Provide a safe environment/Manage emergency situations (25%), and Participate in QA/CQI, interdisciplinary activities, and professional practice activities (8%). Layered on top is a modality-based blueprint where Interventional Radiology alone carries 35% - the single heaviest weight of any category - followed by CT and MRI at 20%, and Diagnostic Imaging/Fluoroscopy/Breast Health, Ultrasound/Vascular Ultrasound, and Nuclear Medicine/PET/Radiation Therapy each at 15%.
Interventional Radiology & Domain 4 (Safety/Emergency)
- Prioritize interventional content given its 35% modality weight
- Layer in emergency management scenarios from Domain 4 (25%)
Domains 1 & 2 (Assessment and Interventions)
- Cover patient assessment and care planning frameworks
- Study therapeutic intervention monitoring across CT/MRI (20% each)
Domain 3 and Remaining Modalities
- Patient/family teaching content (17%)
- Ultrasound, Nuclear Medicine/PET/Radiation Therapy (15% each)
Domain 5 and Full Review
- QA/CQI and professional practice content (8%)
- Full-length timed practice under 3-hour, closed-book conditions
For a domain-by-domain breakdown of exactly what's tested in each category, our CRN exam domains guide maps content expectations to each of these five areas. And since the exam is scored against a defined threshold rather than a curve, understanding exactly what you need to hit is worth reviewing in our CRN passing score breakdown before you finalize your study calendar.
Key Takeaway
Spend your first two study weeks on Interventional Radiology content - its 35% modality weight makes it the single highest-yield category on the entire exam.
Once your content review is complete, timed practice under realistic conditions is what actually protects your registration fee. Running full-length practice sessions through our CRN practice test platform before test day helps confirm you can sustain focus and accuracy across the full 150-question, 3-hour format - the same closed-book conditions you'll face at the C-NET testing center. A quick reference like our CRN cheat sheet can also help during final review, though it's no substitute for full-length timed reps on the practice platform.
