Medical Tests Certified Emergency Nurse Exam FAQ: What Candidates Ask Most

What is the Medical Tests CEN exam?

The CEN exam is the official Board of Certification for Emergency Nursing (BCEN) exam behind the Medical Examination certification, validating the skills measured by the Medical Tests Certified Emergency Nurse credential. It sits at the Professional level of the Board of Certification for Emergency Nursing (BCEN) certification program. It also connects to CPEN (Certified Pediatric Emergency Nurse), TCRN (Trauma Certified Registered Nurse), CFRN (Certified Flight Registered Nurse), CTRN (Certified Transport Registered Nurse), so the knowledge you build here carries over to those tracks as well.

How many questions are on the CEN exam, and how much time do I get?

The CEN exam contains 175 (150 scored + 25 unscored pretest questions) questions to be completed within 180 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

What score do I need to pass the CEN exam, and what does it cost?

The passing score for the CEN exam is 106 of 150 scored questions answered correctly, and the official registration fee is USD 380 (standard individual fee; discounts may apply). Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 195 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

Are there any prerequisites for the CEN exam?

Candidate must hold a current, unrestricted Registered Nurse (RN) license or an internationally equivalent credential accepted by BCEN. Two years of emergency nursing experience is recommended but not required. Requirements can change when Board of Certification for Emergency Nursing (BCEN) revises its certification program, so confirm the current eligibility rules on the official exam page before you register.

Can I try the CEN practice questions before I buy?

Yes. Getcertkey provides a free CEN PDF demo so you can review the question style and answer quality before purchasing. Every purchase also includes 365 days of free updates — if Medical Tests revises the exam during that period, the updated material reaches you at no cost. Once the free-update year ends, you can extend your update service at a 50% discount.

What if I fail the CEN exam, and how is my order delivered?
