CPEN Certification: What the Certified Pediatric Emergency Nurse Exam Asks, Who Sits It and How to Pass

BCEN's ten published sample questions are all one stem, four options, one best answer. On the day you see 175 items: 150 count, 25 are unscored pretest items, and BCEN neither positions the pretest items at the end nor lets you tell them apart, so the only workable policy is to treat all 175 as live. Five unscored tutorial questions run before the 180-minute clock starts.

BCEN publishes the outline as item counts, not percentages. Drawn to scale the exam is lopsided on purpose: System-Focused Emergencies is 56 of the 150, about 37 percent by our arithmetic, and the two smallest domains together are 24. The tiles below carry BCEN's counts; the two live domain guides link from their tiles.

One requirement: a current, unrestricted RN license from the United States, a US territory, Canada or Australia, or a foreign license verified as equivalent. Any restriction or probation on the license disqualifies. You do not have to be working clinically on the day you apply, as long as the license is active.

BCEN recommends two years in the specialty and requires none. That distinction matters because the two years get repeated as a rule elsewhere. Rule out everything else you have read:

The application itself, the payment methods and the accommodation form are on how to get CPEN certified, in order.

The exam is scored by raw count: the number of the 150 scored items you answered correctly, with no curve against the other candidates in the room. BCEN sets the standard by the Angoff method and equates across forms, so a slightly harder form needs slightly fewer correct answers. The passing score BCEN currently publishes is 110 of 150, and BCEN adds that it is subject to change every few years, after each role delineation study. Quote it with the date, never as a fixed percentage.

BCEN publishes counts, not a pass rate. For calendar 2025 it reports 1,211 exams delivered and 689 passed, with 447 failed and 882 recertifications. Divide and you get about 57 percent of exams delivered; that division is ours, not BCEN's, and no first-time rate exists anywhere. What the counts do and do not tell you, and how to read the per-domain score report, is on the pass rate page.

The free material is better than its reputation. BCEN posts the content outline, ten sample questions, a reference list and a preparation checklist at bcen.org/cpen/study-and-prepare, and sells a practice exam and a review course on top. Everything below is built on that public outline, in the order most candidates need it: questions first, the map second, the paperwork when you are ready to pay.

Three of those four options put a family member between the nurse and the history. Once you see that the three share a flaw, the item is a one-way choice. Ninety more, ten to a sheet, are on the practice page; the reasoning stays under each card.

The credential runs four years. Renew by CE attestation, 100 contact hours across the cycle with at least 75 specific to the clinical specialty and at least 50 from an accredited source (rising to at least 75 accredited for applications on or after January 1, 2027), or renew by retaking the exam. Recertification fees per BCEN as of September 2026 are $280, $210 for ENA members and $195 military. Sitting the exam itself earns no CE.
