Emergency nurses are some of the most adaptable clinicians in healthcare. In a single shift, they may treat a child with a high fever, stabilize a patient in cardiac arrest, manage a trauma case, and de-escalate a mental health crisis. That breadth of knowledge and skill is exactly what the Certified Emergency Nurse (CEN) credential is designed to recognize.
Whether you are working in an emergency department and wondering if certification is worth the effort, or you are early in your ER nursing career and planning your next step, this guide walks you through what the CEN is, how to earn it, and what it can mean for your career.
What is the Certified Emergency Nurse (CEN) certification?
The CEN is a nationally recognized specialty credential awarded by the Board of Certification for Emergency Nursing (BCEN). It validates that a registered nurse has the clinical knowledge, judgment, and skills to provide high-quality care across the full range of emergency situations, from minor injuries to life-threatening conditions.
The CEN covers a wide spectrum of emergency nursing content, including cardiovascular, respiratory, and neurological emergencies, trauma and wound care, toxicological and environmental emergencies, obstetrical and gynecological conditions, and psychosocial presentations. It is widely considered the benchmark credential for emergency department nurses, and it is accredited by the Accreditation Board for Specialty Nursing Certification (ABSNC).
More than 41,000 nurses currently hold the CEN credential, and the certification is accepted at Magnet-recognized hospitals and trauma centers across the country.
The CEN is accredited by the Accreditation Board for Specialty Nursing Certification (ABSNC) and is accepted at Magnet-recognized hospitals and trauma centers nationwide.
How to earn the CEN certification:
Become a registered nurse
The first requirement is holding a current, unrestricted registered nurse (RN) license in the United States, a U.S. territory, Canada, or Australia. If you were educated outside of these countries, your credentials will need to be verified through the Commission on Graduates of Foreign Nursing Schools (CGFNS). There are no additional educational requirements beyond what is needed to obtain your RN license.
Build your emergency nursing experience
No specific work experience is required to sit for the CEN exam. However, BCEN strongly recommends at least two years of experience in emergency or trauma nursing before applying. This is practical advice. The exam is designed to reflect the real-world complexity of emergency care, and nurses with hands-on ER experience tend to be better prepared for the clinical reasoning the exam demands.
Apply through the BCEN
Applications are submitted through your BCEN account at bcen.org. Log in or create an account, navigate to the "My Certification" section, and select "Create New Application" for the CEN. Once your application is approved, you will receive an email from BCEN with a 90-day window in which to schedule and sit for your exam.
Exam fees vary: $380 for non-members of the Emergency Nurses Association (ENA), $285 for ENA members, and $195 for active-duty military personnel. BCEN also offers an optional Test Assurance add-on for $70, which gives you a second attempt at no additional charge if you do not pass on your first try.
Prepare for the exam
The CEN exam is a three-hour, computer-based test consisting of 175 multiple-choice questions. Of those, 150 are scored and 25 are unscored pre-test items used to validate future exam questions. Candidates need to answer approximately 106 questions correctly to pass.
BCEN offers several official study tools, including practice exams, a CEN Review Course through BCEN Learn, and a candidate handbook that outlines the full exam content blueprint. The Emergency Nurses Association (ENA) also offers a CEN review manual and online courses. Many candidates combine official resources with study groups and structured review plans.
In 2024, 3,690 candidates passed the CEN exam out of 7,559 who sat for it. Preparation matters. BCEN recommends committing time every day in the weeks leading up to your exam date.
Take the exam
You can take the CEN exam in person at one of more than 300 PSI testing centers nationwide, or through a Live Remote Proctor option that allows you to test from a location of your choice. Results are reported as Pass or Fail, with official score reports mailed after the exam. If you do not pass, you may reapply after 90 days.
Benefits of the CEN certification:
Clinical confidence and expertise
Preparing for the CEN pushes you to deepen your knowledge across every area of emergency nursing, not just the conditions you see most often on your unit. Many nurses find that the process of studying for the exam surfaces gaps in their knowledge they did not realize existed, and that working through the material makes them sharper at the bedside.
Professional recognition
Earning the CEN signals to your employer, your colleagues, and your patients that you have met a rigorous national standard for emergency nursing practice. Hospitals pursuing Magnet Recognition or trauma center designation often prioritize CEN-certified staff when making hiring and promotion decisions.
Career advancement
Certified emergency nurses are consistently considered ahead of non-certified peers for leadership roles, preceptor assignments, and specialized response teams. Many organizations have salary tiers or certification bonuses tied to the CEN. Research from BCEN shows that CEN-certified nurses earn an average of nearly $1,400 more per year than their non-certified counterparts.
Better patient outcomes
The evidence base for specialty nursing certification points in a consistent direction: certified nurses deliver better care. The rigorous clinical knowledge required to pass the CEN exam translates directly to improved judgment in fast-moving, high-stakes situations. Emergency nurses and their supervisors consistently link CEN certification to stronger patient outcomes.
Expanded job opportunities
The CEN credential opens doors beyond the standard emergency department. Certified nurses are well-positioned for roles in trauma centers, critical access hospitals, air medical services, disaster response teams, and federal health contracts. For nurses interested in per diem or travel work, the CEN is especially valuable. Many facilities seek CEN-certified nurses for faster onboarding and higher-acuity assignments.
Maintaining your CEN certification
The CEN credential is valid for four years. When it comes time to renew, you have two options: complete 100 contact hours of continuing education (CE) or retake the CEN exam. If you choose the CE path, at least 75 of the 100 hours must be clinical content specific to emergency nursing, and at least 50 hours must come from an accredited provider such as BCEN Learn, the ENA, AACN, ANCC, or a state board of nursing.
BCEN offers a CE Tracker in your account to help you log and monitor your progress toward renewal. Approximately 10 percent of renewal applications are selected for audit, so it is worth keeping documentation of your CE hours organized and accessible.
Is the CEN certification right for you?
If you work in emergency nursing, the CEN is one of the most meaningful credentials you can earn. It is a direct reflection of the work you do every day and a concrete way to demonstrate that your clinical knowledge meets a nationally recognized standard.
It is not a requirement to practice, but it does set you apart. Whether your goal is a leadership role, a higher salary, better access to per diem and travel opportunities, or simply the confidence that comes from knowing your skills have been validated, the CEN is a strong investment in your career and in the patients who depend on you.
The CareRev app empowers healthcare professionals to find and claim local per diem shifts on demand. Choose the days you work and pick shifts that fit your schedule, whether that's days, evenings, or nights.
