CEN vs TCRN, CPEN, CFRN, CTRN and CBRN: Which BCEN Certification Fits Your Practice

Six BCEN certifications side by side

The Board of Certification for Emergency Nursing runs six certification programs, all accredited by ABSNC. Each has its own overview, FAQ and eligibility page on bcen.org, checked for this guide on October 27, 2026:

The non-member fee is $380 for each. ENA is the Emergency Nurses Association, STN the Society of Trauma Nurses, ASTNA the Air & Surface Transport Nurses Association, and ABA the American Burn Association.

The CTRN note. BCEN's CTRN FAQ lists 155 items with 130 scored, but its passing-score answer reads "99 of the 150 scored items." The two answers don't agree, so ask BCEN for the current CTRN standard before relying on either.

What is the same across every BCEN exam

Much of what Passy's CEN guides explain carries over to the other five:

• Eligibility. Each eligibility page asks for a current, unencumbered RN license in the United States, a U.S. territory, Canada or Australia, or a verified foreign equivalent. BCEN recommends at least two years of experience in the specialty and adds that "this is not required." The CEN eligibility guide walks through the application
• Delivery and retakes. All are BCEN exams delivered by PSI, at test centers or through Live Remote Proctoring, with a 90-day wait after a failed attempt
• Scoring method. Each FAQ says the passing score "is not based on a curve" and can change after that specialty's role delineation study
• Recertification. BCEN's recertify page applies the same rules to all six: every four years, 100 CE hours or the exam, $280 or $210 with the matching association. The CEN recertification guide has the CE details

So the choice between them is about content, not about paperwork or price.

CEN or TCRN: emergency breadth or trauma depth

In Passy's October 2026 autocomplete check, this pairing had more search variations than any other BCEN comparison. The two credentials overlap on injured patients but are built differently.

The CEN outline has no trauma area. Trauma sits inside the clinical areas: cardiovascular, respiratory, gastrointestinal, genitourinary, gynecological and obstetric trauma, head and spinal cord trauma, maxillofacial and ocular trauma, and most musculoskeletal and wound topics. Around them sit medical, mental health, toxicology, communicable disease and professional topics. BCEN describes the TCRN instead as a credential for nurses who care for trauma patients "from injury through rehabilitation," which reaches beyond the emergency department.

Is the CEN or the TCRN harder? BCEN doesn't say. Its 2025 statistics give counts, and here is Passy's arithmetic from them:

Those numbers don't measure difficulty for you. The two exams test different content with different candidate groups, the 2025 CEN results came from the outline and standard used before July 6, 2026, and the passing standards (99 and 96 of 150) were each set for their own exam, so they aren't on one scale. The how-hard guide explains the CEN counts in detail. Choose by your practice: an ED nurse who sees every kind of patient fits the CEN; a nurse whose work follows trauma patients across units fits the TCRN. Holding both is allowed (see below). If you settle on the CEN, see how planned CEN practice is organized by the outline's 11 areas.

CEN or CPEN in a pediatric or mixed ED

The CEN isn't an adult-only exam. Its July 2026 outline names croup, intussusception and neonatal resuscitation inside its regular areas. But children are one population among many on the CEN, while the CPEN is built entirely around pediatric emergency care, from neonates through adolescents. Both offer the $285 rate to ENA members, and BCEN's CPEN fee page lists the same $380 standard price and $200 retest as the CEN.

A practical way to choose: if most of your patients are children, as in a pediatric ED, the CPEN matches your work. If you see all ages, the CEN does, and its pediatric topics are a slice of a wider exam. Once the CEN is your choice, compare the planned CEN access periods against your test date.

CFRN and CTRN for transport nurses

The CFRN and CTRN both serve transport nursing, and both offer the $285 rate to ASTNA members. BCEN describes the CFRN as the credential aligned to air transport and the CTRN as "the only certification built specifically for ground transport nursing." The CFRN changed recently: its FAQ says an updated CFRN content outline took effect on August 31, 2026, with a passing standard of 102 of 150 from that date. The CTRN is the shortest BCEN exam, at 155 items.

If you work in an ED and fly or ride occasionally, the CEN still fits your main practice; transport-specific content belongs to these two.

CBRN for burn nurses

The CBRN is BCEN's credential for burn care across all phases of treatment, with the $285 rate for American Burn Association members. In BCEN's 2025 statistics, 336 CBRN exams were delivered and 1 certificant recertified, out of 722 total CBRN certificants. Burns also appear on the CEN outline, in the Environment and Toxicology area, but only as one topic among many.

Holding more than one BCEN certification

You can hold several. BCEN's recertify page says the same CE hours can count toward more than one certification "as long as the content is relevant to both specialties" and fall within each credential's own 4-year period. Each credential is still recertified with its own application and fee.

If you plan a second credential, start with the one that matches the larger share of your patients. If you're weighing an AACN critical care credential instead, Passy's PCCN or CCRN guide explains how AACN matches its exams to patient acuity.

Choosing your first BCEN exam

A practical approach, not a BCEN rule:

1. Write down your last month of patients. Rough shares by age group, trauma versus medical, and setting.
2. Open the outline of each candidate credential. Compare its areas with your list. The CEN content outline guide has the CEN's 11 areas and item counts.
3. Pick the closest match, then plan the gaps. Every outline will include topics you rarely see; budget extra study weeks for them.
