CTRN Passing Score 2026: Exactly What You Need to Pass

The Exact CTRN Passing Score for 2026

If you're preparing for the Certified Transport Registered Nurse exam, the number you actually need to know is simple: 99 correct answers out of 150 scored questions. That is the passing standard set by the Board of Certification for Emergency Nursing (BCEN), the organization that owns and administers CTRN, with PSI delivering the exam itself. There is no separate "cut score curve" or shifting percentage you need to guess at - BCEN publishes this as a fixed number of correct responses required to earn the credential.

Doing the math, 99 out of 150 works out to approximately 66% correct on the scored items. That percentage is useful for mental math while you're building practice tests on our CTRN practice test platform, but remember that the official pass/fail determination is based on the raw count of correct answers, not a rounded percentage.

How BCEN Calculates Your CTRN Score

The CTRN exam is a fixed-length test: 150 scored multiple-choice questions delivered within a 3-hour testing session. Because the passing threshold is a set number of correct answers rather than a percentile ranking against other candidates, your score is not affected by how easy or hard the test felt to anyone else sitting for it that testing window. You either answer at least 99 items correctly, or you don't.

This matters for how you prepare. Instead of chasing an abstract "average" difficulty level, your real task is to consistently answer questions correctly across all four content domains, since a weak showing in any single domain can quietly drag your total below 99. For a deeper look at how tough candidates generally find this threshold in practice, see How Hard Is the CTRN Exam? Complete Difficulty Guide 2026.

Domain Weighting and What It Means for Your Score

BCEN's current exam outline organizes the 150 scored questions across four domains, each with its own question count. Understanding these counts is the single most practical thing you can do to protect your passing score, because it tells you exactly how many points are riding on each content area.

Domain 3, Patient Conditions and Principles of Management, is by far the largest single content area at 43.3% of the scored exam - nearly 3 out of every 7 questions you see. A candidate who is weak on trauma, cardiac, respiratory, and neurological transport management is putting a huge share of their possible points at risk before the exam even begins. For a full breakdown of what falls under each of these four domains and the specific topics BCEN expects you to know, read CTRN Exam Domains 2026: Complete Guide to All 4 Content Areas.

Exam Format, Timing, and Question Style

The CTRN exam gives you 3 hours to work through 150 scored questions, plus any unscored pretest items mixed in. That's a generous window per question on paper, but ground transport scenarios are often written as multi-sentence clinical vignettes, so budgeting your time by domain - rather than assuming every question takes the same amount of time - is a smarter approach than a flat per-question pace.

You can sit for the exam at a PSI testing center or through live remote proctoring, which gives working transport nurses more flexibility around shift schedules. Neither format changes the content or the passing standard; both simply deliver the same 150-question, 3-hour exam under proctored conditions.

Registration, Fees, and Eligibility Mechanics

Before your score even enters the picture, you need to be eligible to sit for the exam. BCEN requires 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 strict requirement to register - a detail worth understanding fully before you commit to a testing date, which is covered in more depth in CTRN Requirements 2026: Eligibility, Prerequisites & How to Qualify.

On the financial side, the initial exam fee is $285 for members of the Air & Surface Transport Nurses Association (ASTNA) and $380 for nonmembers. That fee difference is significant enough that many candidates join ASTNA before registering simply to reduce the out-of-pocket cost. For the complete cost picture, including what renewal and retake fees typically look like, see CTRN Certification Cost 2026: Complete Pricing Breakdown.

Where to Focus Your Study Time by Domain

Since the passing score is a fixed 99 out of 150, the smartest prep strategy is proportional: spend more study time on the domains carrying the most questions, without completely neglecting the smaller ones. A candidate who masters Domain 3 but skips Domain 4 entirely can still lose the exam on 23 avoidable questions.

How Many Wrong Answers Can You Afford?

With 150 scored questions and a passing standard of 99 correct, you can afford to miss up to 51 questions and still pass. That built-in margin is worth internalizing, because test anxiety often makes candidates feel like every single question is make-or-break. It isn't. A handful of missed questions in Domain 4 (Special Populations), for example, won't sink you if you're performing strongly in Domain 3.

That said, the margin shrinks quickly if you're weak across multiple domains at once. Missing a large share of the 65-question Patient Conditions domain is much harder to recover from than missing a similar share of the 22-question General Principles domain, simply because of the raw number of points involved.

After You Pass: Certification Validity and Renewal

Once you clear the 99-question threshold, CTRN certification is valid for four years. Renewal can be completed either by retaking the exam or by accumulating 100 continuing education contact hours during the certification period. Most working transport nurses choose the continuing education route since it fits naturally alongside ongoing clinical education requirements, but retaking the exam remains an option if that better suits your schedule.

If you're weighing whether pursuing CTRN certification is worth the fee and study time in the first place, especially relative to career paths and the transport nursing roles that specifically list CTRN as preferred or required, Is the CTRN Certification Worth It? Complete ROI Analysis 2026 and CTRN Salary Guide 2026: Complete Earnings Analysis cover that ground in detail.

Whichever route you take, running through realistic scored practice sessions on our practice exam platform before test day remains one of the most direct ways to confirm you're consistently clearing 99 correct answers across full-length, domain-weighted practice tests - not just in isolated topic drills.
