What the CTRN Actually Tests
The Certified Transport Registered Nurse (CTRN) credential, administered by the Board of Certification for Emergency Nursing (BCEN) and delivered through PSI testing centers, validates the specialized judgment required to manage critically ill and injured patients in a moving ground transport environment - not a fixed ICU bay, not a helicopter, but an ambulance or critical care ground unit where space, equipment, and time are all constrained. If you're still sorting out how this credential differs from other transport-focused designations, our overview of what CTRN actually is and the deeper dive into the CTRN certification itself are good starting points before you open a single practice question.
This guide is built specifically around BCEN's current CTRN outline - the one that governs the exam you'll sit for in 2026. Everything below, from the domain weighting to the passing standard, comes directly from that outline. No borrowed numbers, no generic transport-nursing platitudes.
Exam Format, Timing, and Passing Standard
The CTRN exam consists of 150 scored questions, and you're given 3 hours to complete them. That works out to roughly 72 seconds per question on average - workable, but not generous if you're second-guessing scenario-based items. The passing standard is fixed at 99 correct answers out of the 150 scored questions. That number matters more than any percentage you'll see floating around online, because BCEN reports pass/fail based on that raw scored count rather than a curved percentage. For the full mechanics of how that standard is set and what it means for your prep, see our dedicated breakdown of the CTRN passing score.
You can sit for the exam at a PSI testing center or through live remote proctoring from home or a private office - a meaningful convenience if you're working rotating shifts and can't easily block out travel time to a test center. Scheduling logistics, blackout considerations, and how far in advance to book are covered in our guide to CTRN exam dates and scheduling.
Key Takeaway
Treat the 99-out-of-150 threshold as your target, not 66% or any rounded percentage. Track your practice exam performance in raw correct-answer counts so your self-assessment matches how BCEN actually scores you.
Registration, Fees, and Eligibility
Registration cost depends on your membership status with the Air & Surface Transport Nurses Association (ASTNA). Members pay $285; nonmembers pay $380. If you're transport-active and not yet an ASTNA member, it's worth running the math - membership dues plus the member rate can sometimes land close to the nonmember fee anyway, while also giving you access to ASTNA's clinical resources. A full cost breakdown, including how this fee fits into your total certification investment, is available in our CTRN certification cost guide.
Eligibility is more flexible than many candidates assume. You need a current, unrestricted RN license from the United States, a U.S. territory, Canada, Australia, or an accepted international equivalent. Two years of ground transport nursing experience is recommended, but it is not a mandatory prerequisite - meaning nurses transitioning into transport roles from ED or critical care backgrounds aren't automatically locked out. Our detailed CTRN requirements guide walks through every eligibility scenario, including how the "recommended" experience language actually gets interpreted in practice.

The Four CTRN Domains, Question by Question
BCEN's current outline took effect March 30, 2026, following the 2025 ground transport nursing role delineation study - meaning the four domains and their weighting reflect a fresh look at what ground transport nurses actually do on shift, not a decade-old snapshot. There are four domains, and the scored question counts are fixed: 22, 40, 65, and 23 questions respectively. If you want the fully expanded version of each domain with subtopic lists, our CTRN exam domains guide covers all four in depth. Here's the condensed version for planning purposes.
Domain 1: General Principles of Ground Transport Nursing Practice (22 questions, ~14.7%)
This domain covers the operational and professional-practice backbone of the job - the things that don't show up in a standard ICU orientation but define transport nursing as its own discipline.
- Legal, ethical, and regulatory considerations unique to interfacility and scene transport
- Safety practices for ground units, including scene safety and vehicle-specific hazards
- Communication and handoff protocols across sending and receiving facilities
- Quality improvement and documentation standards specific to transport
Domain 2: Resuscitation Principles (40 questions, ~26.7%)
The second-largest domain, and one where transport-specific nuance matters far more than generic ACLS recall. Expect scenario items that force you to apply resuscitation algorithms inside the constraints of a moving vehicle.
- Airway management and rescue techniques in confined transport spaces
- Hemodynamic support, fluid resuscitation, and vasopressor titration en route
- Recognition and management of shock states during transport
- Equipment and monitoring limitations unique to ground units
Domain 3: Patient Conditions and Principles of Management (65 questions, ~43.3%)
This is the largest domain by a wide margin - nearly half the exam - and it's where most candidates should concentrate the bulk of their study hours.
- Neurologic, cardiovascular, respiratory, and trauma emergencies in the transport context
- Toxicologic, metabolic, and infectious disease presentations
- Multi-system trauma prioritization and en-route deterioration management
- Pharmacologic management specific to critical care transport scope
Domain 4: Special Populations (23 questions, ~15.3%)
Covers patients whose transport needs diverge from the standard adult trauma or medical patient - a category that's easy to under-study because it feels "less common" until it appears on the exam.
- Obstetric and neonatal transport considerations
- Pediatric-specific assessment and intervention adjustments
- Bariatric, geriatric, and behavioral health transport challenges
- Interfacility transfer nuances for medically complex populations
Building a Domain-Weighted Study Timeline
Generic study advice - flashcards, spaced repetition, timed blocks - only helps if it's pointed at the right material in the right order. Below is a sample allocation built around the CTRN's actual domain weighting rather than an evenly split calendar.
Patient Conditions and Principles of Management
- Work through cardiovascular, neuro, and trauma emergency scenarios first - this domain carries 65 of 150 scored questions
- Build condition-specific decision trees rather than memorizing isolated facts
Resuscitation Principles
- Drill airway, shock, and hemodynamic management scenarios specific to ground transport constraints
- Practice applying algorithms under simulated time pressure
Special Populations
- Cover obstetric, neonatal, pediatric, and geriatric transport nuances
- Don't skip this domain just because it's smaller - 23 questions is still enough to swing a borderline score
General Principles of Ground Transport Nursing Practice
- Review safety, legal/ethical, and documentation standards
- Take a full-length timed practice exam and review every missed item against its domain
For a deeper look at how challenging candidates generally find each domain and where most missed questions cluster, see how hard the CTRN exam really is. And if you want outcome context before you commit to a study timeline, our review of CTRN pass rate data is worth reading alongside this plan.
High-Yield Clinical Topics to Master
Given the domain weighting, certain clinical areas deserve disproportionate attention:
- Trauma prioritization during multi-patient or prolonged transport - a recurring theme across both Resuscitation Principles and Patient Conditions
- Shock differentiation (hypovolemic, cardiogenic, distributive, obstructive) and how presentation shifts en route
- Airway rescue in confined spaces where standard equipment access is limited
- Neonatal and pediatric transport physiology, since these populations behave differently under transport stressors than adults
- Toxicologic and metabolic emergencies, which are frequently underrepresented in candidates' self-study but scored heavily within Domain 3
Keep a running list of weak areas as you work through practice questions on our CTRN practice test platform, and revisit that list weekly rather than only at the end of your prep cycle. For quick pre-exam review, our CTRN cheat sheet condenses the highest-yield facts from all four domains onto a single page.
Who Actually Hires CTRNs
CTRN-certified nurses typically work for ground critical care transport services, interfacility transfer teams, and EMS-affiliated critical care units - organizations that move patients between facilities or from scene to definitive care by ambulance rather than rotor or fixed-wing aircraft. Many employers treat the credential as a strong differentiator during hiring and promotion decisions, even when it isn't an absolute requirement for the role. If you're weighing whether the certification will move the needle for your career, our CTRN jobs overview and CTRN salary guide break down where this credential tends to matter most, and our ROI analysis weighs the certification cost against the career upside.
Maintaining Your Certification
Once earned, the CTRN credential is valid for four years. Renewal can be completed either by retaking the exam or by accumulating 100 continuing education contact hours relevant to transport nursing practice. Most working transport nurses find the CE-hours path more practical given ongoing shift demands, but retesting remains a valid option if you'd rather refresh your knowledge against the current outline. Since the outline itself gets updated periodically - as it did with the 2025 role delineation study behind the current version - nurses who renew by exam should confirm they're studying against the version in effect at the time of their test.
Key Takeaway
Start tracking CE hours the moment you pass, rather than scrambling in year three. Transport-relevant conferences, resuscitation courses, and trauma education typically qualify.
