What Does CTRN Stand For?
CTRN stands for Certified Transport Registered Nurse. It's a specialty nursing certification that validates advanced clinical judgment for nurses who care for critically ill or injured patients during ground transport - the period between the scene or a referring facility and definitive care. Unlike a generic critical care credential, the CTRN exam blueprint is built specifically around the realities of moving a patient in a vehicle: limited space, limited equipment, changing physiologic status en route, and the need to make independent decisions without immediate backup.
If you're just starting to research the letters themselves, our companion pages on CTRN meaning, what CTRN is, and what CTRN means cover the terminology from slightly different angles. This article focuses on the practical side: who administers the exam, what it tests, and how the pieces fit together for a candidate planning to sit for it.
Who Issues the CTRN Credential?
The CTRN is administered by the Board of Certification for Emergency Nursing (BCEN). BCEN sets the eligibility rules, writes and maintains the exam outline, determines the passing standard, and manages renewal. Actual test delivery - the software, the testing centers, and the proctoring - is handled by PSI, either in person at a PSI center or through live remote proctoring for candidates who prefer to test from a private location.
Because BCEN periodically updates the exam blueprint based on formal practice analyses, the content weighting you study from should always match the current outline. The version referenced throughout this article reflects the outline that took effect March 30, 2026, following a 2025 ground transport nursing role delineation study. For a full walkthrough of how that update changed things, see our detailed breakdown of the CTRN exam domains.
The Four CTRN Exam Domains
The CTRN exam draws its 150 scored questions from four domains. Knowing the exact weight of each domain matters more than most candidates realize - it tells you where to spend your limited study hours.
| Domain | Scored Questions | Approximate Weight |
|---|---|---|
| Domain 1: General Principles of Ground Transport Nursing Practice | 22 | 14.7% |
| Domain 2: Resuscitation Principles | 40 | 26.7% |
| Domain 3: Patient Conditions and Principles of Management | 65 | 43.3% |
| Domain 4: Special Populations | 23 | 15.3% |
Domain 1: General Principles of Ground Transport Nursing Practice
This domain covers the operational and professional foundation of ground transport nursing - safety protocols, communication with dispatch and receiving facilities, legal and ethical considerations unique to moving a patient between sites, and team dynamics inside a transport unit.
- Scene safety and vehicle operations awareness
- Interfacility communication and handoff standards
- Legal/ethical scope-of-practice issues specific to transport
Domain 2: Resuscitation Principles
The second-largest domain, testing your ability to manage airway, breathing, and circulation emergencies in a moving vehicle with constrained resources.
- Advanced airway management in transit
- Shock recognition and hemodynamic support
- Cardiac arrest management with limited personnel
Domain 3: Patient Conditions and Principles of Management
The single largest domain at 43.3% of scored content. This is where the exam tests depth across body systems - cardiovascular, respiratory, neurologic, trauma, metabolic, and more - and expects you to apply management principles under transport-specific constraints.
- Multi-system trauma prioritization
- Neurologic emergencies and deteriorating status en route
- Medical emergencies requiring ongoing titration during transport
Domain 4: Special Populations
Covers patients whose transport needs differ from the general adult population - pediatric, obstetric, geriatric, bariatric, and psychiatric or behavioral health patients.
- Pediatric and neonatal physiologic differences
- Obstetric emergencies during ground transport
- Behavioral health safety considerations in a confined vehicle
For a question-by-question breakdown of subtopics inside each domain, the CTRN Exam Domains 2026 guide goes considerably deeper than what fits here.
Exam Format, Timing, and Scoring
Candidates answer 150 scored questions in 3 hours. To earn the credential, you need 99 correct answers out of 150 scored questions - that's the passing standard set by BCEN's current outline. The exam is delivered as a computer-based test through PSI, either at a testing center or via live remote proctoring if you'd rather sit for it somewhere private.
Key Takeaway
Because the passing standard is a fixed raw score (99 of 150), every domain contributes to the same pool of points - there's no separate pass/fail cutoff per domain, which means a strong Domain 3 performance can offset a weaker area elsewhere.
If you want the mechanics of the scoring standard explained in more detail, including how BCEN arrives at that number, read CTRN Passing Score 2026: Exactly What You Need to Pass. And if you're trying to gauge how tough the exam actually feels in practice, How Hard Is the CTRN Exam? and CTRN Pass Rate 2026 both address that from different angles.
Who Can Sit for the CTRN?
Eligibility for the CTRN is built around licensure rather than a rigid experience mandate:
- A current, unrestricted RN license issued in the United States, a U.S. territory, Canada, Australia, or an accepted international equivalent
- Two years of ground transport nursing experience is recommended but not required - you can technically sit for the exam without it, though most candidates find the experience helps considerably with the scenario-based questions
This relatively open eligibility structure is one reason the CTRN attracts nurses at different points in their transport careers, not just seasoned veterans. For the complete eligibility checklist, including documentation you'll need at registration, see CTRN Requirements 2026.
Registration and Fees
The CTRN initial exam fee depends on your membership status with the Air & Surface Transport Nurses Association (ASTNA):
- $285 for ASTNA members
- $380 for nonmembers
That fee difference is large enough that many candidates join ASTNA before registering simply to offset the membership cost against exam savings. For a full breakdown of what's included in that fee, retake costs, and renewal pricing, visit CTRN Certification Cost 2026: Complete Pricing Breakdown. Scheduling windows and how far in advance you should register are covered in CTRN Exam Dates 2026.
Who Hires Nurses With a CTRN?
Because the certification is built specifically around ground transport scenarios, it signals something distinct to employers compared to a general critical care or emergency credential. Ground ambulance critical care transport teams, interfacility transfer services, and specialty transport programs (neonatal, pediatric, or trauma-focused ground units) tend to look for the CTRN specifically when hiring or promoting transport RNs, because it demonstrates competency in exactly the environment those roles operate in - not just critical care knowledge in the abstract.
If you're evaluating whether pursuing the credential makes sense for your career trajectory, Is the CTRN Certification Worth It? lays out the return-on-investment considerations, and CTRN Salary Guide 2026 discusses how the credential factors into compensation conversations.

Building a Domain-Weighted Study Plan
Given that Domain 3 (Patient Conditions and Principles of Management) makes up 43.3% of the scored exam, it deserves proportionally more of your study calendar than the other three domains combined would suggest at first glance. Domain 2 (Resuscitation Principles) at 26.7% is the second priority, followed by Domains 1 and 4, which are smaller but not skippable - together they still account for roughly 30% of your score.
Domain 3 Foundations
- Work through cardiovascular, respiratory, and neurologic emergency management
- Build a running list of transport-specific complications for each system
Domain 2 and Remaining Domain 3 Content
- Drill airway and shock management scenarios
- Finish trauma and metabolic sections of Domain 3
Domain 1 and Domain 4
- Review operational/legal content and special population physiology
- Focus extra time on pediatric and obstetric transport differences
Full-Length Practice and Weak-Area Review
- Take timed practice sets under 3-hour conditions
- Revisit any domain where scores lag behind the 99/150 target
Spacing your review sessions and revisiting weaker domains a few days after first exposure (rather than cramming everything into one sitting) tends to help retention stick for the scenario-based question style this exam uses. For a structured, week-by-week plan built entirely around these four domains, see the CTRN Study Guide 2026. When you're ready to test your recall under timed conditions, our CTRN practice test platform mirrors the 3-hour, 150-question structure so there are no surprises on exam day.
Keeping the Credential Current
The CTRN is valid for four years. Renewal can be completed in one of two ways: retaking the exam, or accumulating 100 continuing education contact hours relevant to transport nursing practice. Most working CTRNs choose the CE route since it fits more naturally around a full-time transport schedule, but retaking the exam remains an option if you'd rather demonstrate current knowledge directly.
