What Is CTRN Certification?
The Certified Transport Registered Nurse (CTRN) credential recognizes registered nurses who demonstrate specialized knowledge in ground transport nursing practice. It is not a generic critical care badge - it is built specifically around the clinical decisions, resource limitations, and patient handoffs that define transport environments. If you're new to the credential entirely, our companion pieces on What Is CTRN? and CTRN Meaning walk through the basics before you dive into exam mechanics.
Because "CTRN" happens to be reused by other credentialing bodies for unrelated specialties, it's worth being precise: this article covers only the Certified Transport Registered Nurse exam governed by the Board of Certification for Emergency Nursing (BCEN). If you want the acronym broken down letter by letter, see What Does CTRN Stand For? and What Does CTRN Mean?.
Who Administers the CTRN Exam
BCEN owns and maintains the CTRN content outline, while PSI delivers the actual testing experience. Candidates can sit for the exam either at a physical PSI test center or through live remote proctoring from a private location, which gives transport nurses working irregular shifts more flexibility in scheduling. For a deeper look at scheduling windows and deadlines, check CTRN Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
If you're still deciding whether this is the right acronym and credential for your career path, the overview at CTRN Certification and the deeper explainer at What Is A CTRN? can help confirm you're pursuing the ground transport nursing credential rather than a similarly-named certification.
Eligibility Requirements
BCEN keeps the eligibility bar accessible relative to how demanding the exam content itself is. To sit for CTRN, you need:
- A current, unrestricted RN license issued in the United States, a U.S. territory, Canada, Australia, or an accepted international equivalent.
- No mandatory transport experience - though two years of ground transport nursing experience is strongly recommended before attempting the exam.
Notice there's no minimum year requirement to register, which surprises a lot of newer transport nurses. That said, the exam questions are written assuming real-world exposure to transport scenarios, so nurses without hands-on time often need to compensate with more deliberate scenario-based study. Full detail on documentation and application steps is in CTRN Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Exam Format, Fees, and Registration
The CTRN exam consists of 150 scored questions delivered over a 3-hour testing window. The current outline took effect March 30, 2026, following a 2025 ground transport nursing role delineation study that BCEN conducted to keep the content aligned with actual practice.
Registration cost depends on membership status:
| Candidate Type | Initial Exam Fee |
|---|---|
| Air & Surface Transport Nurses Association (ASTNA) Member | $285 |
| Nonmember | $380 |
That fee difference is enough to make ASTNA membership worth evaluating before you register, especially if you plan to renew by exam down the line. For a complete cost breakdown including renewal and retake considerations, see CTRN Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Join ASTNA before registering if you're not already a member - the $95 fee difference often offsets or exceeds typical membership dues.
The Four CTRN Exam Domains
BCEN's outline splits the 150 scored questions across four domains with very uneven weighting. Understanding this distribution should directly shape how you allocate study time - treating all four domains equally is one of the most common preparation mistakes. For a full domain-by-domain breakdown of subtopics, see CTRN Exam Domains 2026: Complete Guide to All 4 Content Areas.
Domain 1: General Principles of Ground Transport Nursing Practice (22 questions, ~14.7%)
Covers the operational and professional foundations of transport nursing - safety protocols, crew resource management, legal and ethical considerations, and communication during handoffs.
- Scene safety and vehicle operation awareness
- Interfacility transfer regulations and documentation
- Team communication under time pressure
Domain 2: Resuscitation Principles (40 questions, ~26.7%)
Focuses on stabilizing critically unstable patients with limited equipment and personnel inside the transport environment.
- Airway management and rescue techniques in confined spaces
- Hemodynamic support and shock recognition
- Cardiac arrest management during transport
Domain 3: Patient Conditions and Principles of Management (65 questions, 43.3%)
The largest and most heavily weighted domain by a significant margin. It covers management of specific medical, trauma, and surgical conditions likely to be encountered en route.
- Trauma stabilization and multi-system injury patterns
- Neurological, respiratory, and cardiovascular emergencies
- Toxicological, metabolic, and environmental conditions
Domain 4: Special Populations (23 questions, ~15.3%)
Addresses transport considerations unique to patients whose physiology or circumstances change standard management approaches.
- Pediatric and neonatal transport differences
- Obstetric emergencies during transport
- Geriatric, bariatric, and behavioral health considerations
Passing Standard
To pass the CTRN exam, candidates must answer 99 of the 150 scored questions correctly within the 3-hour window. There's no domain-specific passing threshold - the 99-correct standard applies to your overall scored performance, meaning strength in Domain 3 can meaningfully offset weaker performance elsewhere, though you shouldn't rely on that as a strategy. A full explanation of how scoring works, including how unscored pretest items factor in, is available at CTRN Passing Score 2026: Exactly What You Need to Pass.

Building a Domain-Weighted Prep Plan
Rather than spreading study time evenly across four domains, weight your schedule to match BCEN's question distribution. A practical way to structure this is to front-load Domain 3 content since it's both the largest domain and the one most likely to blend with resuscitation and special population scenarios in exam vignettes.
Patient Conditions and Principles of Management
- Work through trauma, cardiac, respiratory, and neuro emergency scenarios
- Drill toxicology and environmental exposure presentations
Resuscitation Principles
- Practice airway and shock management decision trees
- Review cardiac arrest algorithms specific to the transport setting
Special Populations and General Principles
- Cover pediatric, neonatal, and obstetric transport differences
- Review safety, legal, and communication protocols
Integrated Review
- Take full-length timed practice sets mixing all four domains
- Revisit weak areas identified from missed practice questions

And when exam day approaches, a condensed reference like the CTRN Cheat Sheet 2026: One-Page Review of Must-Know Facts can help with last-minute review. You can also work through timed, domain-weighted questions on our practice test platform to build familiarity with the pacing required to finish 150 questions in 3 hours.
Certification Validity and Renewal
Once earned, CTRN certification is valid for four years. Renewal can happen one of two ways:
- Retaking and passing the current exam.
- Completing 100 continuing education contact hours relevant to transport nursing practice.
Most working transport nurses choose the continuing education path since it avoids re-testing under the current outline, but retaking the exam can make sense if your CE hours are lagging as your renewal window approaches.
Who Hires CTRNs
CTRN-credentialed nurses are typically employed by ground critical care transport services, interfacility transfer teams, and EMS-affiliated transport agencies that move critically ill or injured patients between facilities. Employers often view the credential as evidence that a nurse can function independently in resource-limited settings without direct physician oversight during transit.

For nurses building formal preparation into their transport nursing career path, structured coursework referenced in CTRN Training can complement self-study, particularly for candidates who haven't yet hit the recommended two years of ground transport experience.
