CPEN certification at a glance

CPEN — Certified Pediatric Emergency Nurse — is the RN-level benchmark for pediatric emergency nursing. The credential is issued by the Board of Certification for Emergency Nursing (BCEN), which launched the exam in January 2009.

CPEN began as a 50-50 partnership between BCEN and the Pediatric Nursing Certification Board (PNCB). In June 2016 the two boards dissolved that partnership, and BCEN became the sole owner of CPEN. You may still see the credential listed as "BCEN/PNCB" in older references.

CPEN is a board certification, not a course. It is sometimes confused with CPN — the PNCB's general Certified Pediatric Nurse credential — but only CPEN validates pediatric emergency nursing specifically.

Am I eligible for the CPEN exam?

Yes — if you hold a current, unencumbered RN license in the United States, a US territory, Canada, or Australia. BCEN does not enforce a minimum-hours rule for CPEN.

An international nursing certificate equivalent to a US RN license is also accepted, provided it is verified through TruMerit (BCEN's international credential-evaluation partner). Any active restriction, suspension, or probation on a nursing license disqualifies a candidate.

BCEN recommends at least two years of pediatric emergency nursing experience before testing. That recommendation is guidance, not a gate — you may sit the exam without it.

You are a strong candidate if…

  • You have roughly two years of pediatric emergency RN practice, in a pediatric ED, mixed ED, or children's hospital.
  • You triage children confidently using the Pediatric Assessment Triangle (PAT) and an acuity tool such as ESI.
  • You routinely manage respiratory, cardiac, neurologic, and multi-system pediatric emergencies, including sepsis and anaphylaxis.
  • Your setting fits a recognized pediatric emergency role: pediatric or mixed ED, children's hospital, pediatric trauma center, urgent care, or prehospital and critical-care transport.

CPEN exam blueprint — six domains (150 scored items)

The CPEN blueprint is six domains, weighted by where most pediatric emergency nursing decisions happen. System-Focused Emergencies alone carries about 37% of the scored exam — most of your study time should live there.

  • Triage Process (PAT, ESI, emergency preparedness) 20%
  • Assessment (history, physical, pain) 25%
  • System-Focused Emergencies (respiratory, cardiac, neuro, GI/GU, ENT, MSK, heme/onc, endocrine) 56%
  • Special Considerations (neonatal, behavioral health, maltreatment, environmental, toxicology, communicable disease) 25%
  • Multi-System Considerations (sepsis, anaphylaxis, sedation) 12%
  • Professional Issues 12%

Do not neglect Triage and Assessment. Together they account for roughly 30% of scored items and anchor nearly every scenario stem. Professional Issues feels abstract at the bedside but reliably appears on the exam.

Cost, scheduling, and military benefits

BCEN delivers CPEN through Pearson VUE in-person testing centers and via Live Remote Proctoring (LRP) for candidates who prefer to test from a private location. After BCEN approves your application, you receive an Authorization to Test with a scheduling window — book your Pearson VUE seat or LRP slot promptly.

Fee itemCost (USD)
Initial application — ENA member $285
Initial application — non-member $380
Military / veteran application $195 (or $265 with Test Assurance)
Retest (within one year of initial exam) $200
Initial with BCEN Test Assurance — non-member $450
Initial with BCEN Test Assurance — ENA member $355

Renewal

CPEN certification is valid for four years. BCEN offers two renewal pathways. Pathway 1 — Recertification by CE Attestation: complete 100 continuing education contact hours in the cycle and attest to an active, unencumbered RN license. Keep your CE certificates, because BCEN audits a share of renewals.

Pathway 2 — Recertification by Examination: retake and pass the current CPEN exam. Recertification fees mirror the initial-application schedule, and military/veteran and voucher discounts also apply to recertification.

How hard is the CPEN exam?

In 2024, 673 of 1,058 CPEN candidates passed the exam — a pass rate near 64%. That sits in the moderate range for BCEN specialty exams, partly because CPEN spans the full breadth of pediatric emergencies rather than a single body system.

Candidates who follow a structured 8 to 10-week plan and complete at least one full-length timed practice exam pass at meaningfully higher rates than those relying on work experience alone. The biggest avoidable gap is under-studying System-Focused Emergencies, which is more than a third of the scored exam.

An 8-week CPEN study plan

A structured 8-week study plan is enough for most pediatric emergency RNs with two or more years of practice — roughly 60 to 100 total study hours across the six blueprint domains. Practice-question volume ramps through weeks 2–6 and peaks in week 7 with a full-length timed exam; week 8 is for targeted review and a rest day.

How CPEN candidates actually fail — and how to avoid it

Sample CPEN question

This item mirrors BCEN's scenario format: a short pediatric clinical stem, an unstable child, and four plausible options where only one is best. Try it before you read the rationale.

Sample CPEN exam item
A 2-year-old is brought to the pediatric ED with 2 days of fever, lethargy, and poor feeding. On arrival: HR 190, RR 60, capillary refill 4 seconds, mottled skin, and a weak cry. The Pediatric Assessment Triangle shows abnormal appearance and abnormal circulation.
Which nursing action should the pediatric emergency RN prioritize first?

Key CPEN terms every candidate should know

These terms surface across CPEN exam items. Review them until the definitions feel automatic — scenario stems often hinge on recognizing which pediatric framework applies.

CPEN vs. CPN, CEN, and ENPC

CPEN sits alongside several pediatric and emergency credentials that nurses sometimes confuse. Many candidates Google "CPEN" when they actually mean CPN or ENPC, so the distinction matters before you spend time or money.

CredentialBodyScopeBest fit
CPENBCENPediatric emergency nursingRNs caring for children in emergency settings
CPNPNCBGeneral pediatric nursing across settingsRNs in inpatient or outpatient peds
CENBCENAdult and pediatric emergency nursingED RNs covering all presentations
ENPC (course, not cert)ENABaseline pediatric emergency assessmentED RNs as foundational training
TCRNBCENTrauma nursing across the continuumRNs in trauma-touching roles

Take CPEN if you want to validate pediatric emergency expertise specifically. Take CPN instead if your work is general pediatrics across inpatient and outpatient settings. Take CEN if your day-to-day is broad, all-ages ED practice. ENPC is baseline education — it does not replace CPEN on your credentials line.

Frequently asked questions about the CPEN exam

CPEN stands for Certified Pediatric Emergency Nurse. The credential is issued by the Board of Certification for Emergency Nursing (BCEN).

BCEN issues CPEN and has been its sole owner since June 2016. The exam launched in 2009 as a 50-50 partnership between BCEN and the Pediatric Nursing Certification Board (PNCB).

No. CPEN is BCEN's pediatric emergency nursing certification, while CPN is the PNCB's general Certified Pediatric Nurse credential covering pediatric care across all settings.

Yes. BCEN recommends two years of pediatric emergency experience but does not require it. You only need a current, unencumbered RN license.

The CPEN exam has 175 multiple-choice items — 150 scored and 25 unscored pretest items — with a 3-hour time limit.

The CPEN exam costs $285 for ENA members and $380 for non-members. Active-duty service members, reservists, and veterans pay $195, and the retest fee is $200.

The CPEN exam is moderately difficult. The 2024 pass rate was about 64% (673 of 1,058 candidates). Most failures come from under-studying System-Focused Emergencies.

CPEN is valid for four years. You renew by completing 100 continuing education contact hours and attesting to an active RN license, or by retaking and passing the exam.

You can apply to retake the exam at a discounted retest fee of $200 within one year of your initial exam date. BCEN Test Assurance covers a free retest if purchased upfront.

Yes. CPEN is accredited by the Accreditation Board for Specialty Nursing Certification (ABSNC) and accepted by the ANCC Magnet Recognition Program.
