What is the CEN exam?
The Certified Emergency Nurse (CEN) exam is a national specialty-certification exam for registered nurses whose practice involves emergency care. Passing it earns the CEN credential and demonstrates knowledge across the broad scope of emergency nursing—not just the presentations that happen to arrive during your usual shift.
BCEN develops and administers the exam with emergency-nursing subject-matter experts and its testing partner, PSI. The current exam is built from a role delineation study and the official examination content outline effective July 2026. The CEN is a professional certification, not a nursing license and not the same thing as completing a course such as ACLS or TNCC.
The CEN certification program is accredited by the Accreditation Board for Specialty Nursing Certification (ABSNC). It is designed for emergency nurses, but current employment in an emergency department is not itself an eligibility requirement.
How much does the CEN exam cost?
As of September 25, 2026, the CEN exam costs $380 at the standard individual self-pay rate, $285 for Emergency Nurses Association members, or $195 for eligible military applicants.
For an individual applicant who is not using an association, military, or voucher discount.
The reduced BCEN exam fee for current Emergency Nurses Association members. ENA membership dues are separate.
BCEN’s listed rate for eligible active-duty service members, reservists, and veterans.
BCEN Test Assurance
Test Assurance adds $70 to the initial fee: $450 standard, $355 with ENA membership, or $265 at the military rate. If the first attempt is unsuccessful, it provides a no-fee second exam application after the required waiting period. Read the current terms before deciding whether the added cost makes sense for you.
Retest fee and waiting period
Without Test Assurance, BCEN currently lists a standard retest fee of $200. The discounted retest rate is available for applications made within one year of the initial exam date. Candidates must wait 90 days after an unsuccessful attempt; BCEN currently allows unlimited attempts when the waiting period and application requirements are met.
Cost-saving check: Before paying personally, ask whether your employer purchases BCEN vouchers or reimburses specialty-certification expenses. Fees and discount rules can change; verify the total on the official BCEN CEN fees page before submitting an application.
CEN exam format
The current CEN exam contains 175 computer-delivered items. Only 150 are scored; the remaining 25 are unscored pretest items used by BCEN for exam development.
What do the questions look like?
BCEN’s published CEN sample questions use four answer choices and ask for the best, most critical, or priority response. The questions are designed to reflect nursing judgment and the nursing process—not just isolated fact recall. Review the official sample questions to see BCEN’s current published format.
Where can you take it?
The exam is delivered by computer at PSI testing centers and through PSI Live Remote Proctoring. The content and security standard are the same. Your best choice is the setting in which technology, travel, noise, and test-day logistics are least likely to become an additional question you did not study for.
What happens on exam day?
BCEN provides five practice items to familiarize candidates with the testing interface. After the exam, testing-center candidates receive a score report and remote candidates see a pass/fail result on screen; results are also sent by email.
Can you take breaks?
Current BCEN policy permits up to two breaks of no more than 10 minutes each. The exam clock keeps running. Exam-day and identification rules matter, so review the BCEN Candidate Handbook before your appointment.
Nurscience pacing perspective: Three hours for 175 items averages a little over one minute per item. Some questions will take less; protect enough time that one unusually stubborn stem does not quietly adopt the rest of your exam.
What score do you need to pass the CEN?
BCEN’s current CEN FAQ states that candidates must answer 99 of the 150 scored items correctly to pass. That is 66% of the scored items, but BCEN reports the requirement as a raw number correct—not as a school-style percentage grade.
The 25 pretest items do not count toward the score, so the denominator is 150, not 175. The exam is not graded on a curve; your result is based on your own performance. BCEN also notes that the passing standard may change after future role delineation studies, which is one reason an annually updated guide matters.
See BCEN’s current answer under “Exam Scoring Questions” on the official CEN FAQ page.
What is on the CEN exam?
The scored exam is organized into 11 BCEN domains. The counts below add to the 150 scored items; the 25 unscored pretest items are not included in the blueprint totals.
Use the current outline when you choose review materials. Older resources can still contain useful clinical information, but a resource that organizes the exam around an outdated blueprint should not be the only map in the ambulance.

| Professional Issues | 12 | 8.0% |
One useful correction: The current outline has no separate pediatric domain. That does not mean “no pediatrics.” Age-specific topics—including croup, intussusception, neonatal resuscitation, and pediatric presentations of broader emergencies—appear inside the applicable clinical domains.
Free CEN study guides for all 11 exam domains
The exam outline tells you what can be tested. Each domain below links to a focused, exam-relevant Nurscience study guide built around the current July 2026 blueprint. Choose the area costing you points, or work through all 11 in order.
1. Cardiovascular Emergencies
Acute coronary syndrome, dysrhythmias, arrest, heart failure, hypertension, vascular emergencies, tamponade, thromboembolic disease, cardiovascular trauma, and cardiogenic or obstructive shock.
Study lens: Recognize instability early, distinguish competing causes of shock or chest symptoms, and know the next action—not merely the diagnosis.
2. Respiratory Emergencies
Airway obstruction, aspiration, asthma, COPD, infection, pneumothorax, pulmonary embolus, pleural effusion, noncardiac pulmonary edema, respiratory distress syndromes, trauma, pulmonary hypertension, inhalation injury, and croup.
Study lens: Separate airway, ventilation, oxygenation, and perfusion problems; then choose the intervention that addresses the failing physiology first.
3. Neurological Emergencies
Stroke and TIA, seizure disorders, headache, meningitis, increased intracranial pressure, other neurological disorders, head and spinal cord trauma, and neurogenic shock.
Study lens: Time last known well, identify threats to airway or perfusion, recognize rising intracranial pressure, and protect neurologic function while the diagnosis is refined.
4. Gastrointestinal Emergencies
Acute abdominal processes, GI bleeding, obstruction, perforation, peritonitis, hepatobiliary and pancreatic emergencies, esophageal varices, foreign bodies, intussusception, vomiting syndromes, and GI trauma.
Study lens: Identify hemorrhage, ischemia, perforation, sepsis, and obstruction before getting distracted by the very long list of things that can cause abdominal pain.
5. Genitourinary, Gynecology, and Obstetrical Emergencies
Renal and urinary emergencies, torsion, priapism, gynecologic bleeding or infection, ovarian disorders, sexual assault, pregnancy complications, emergent delivery, postpartum problems, trauma, and neonatal resuscitation.
Study lens: Protect fertility, identify hemorrhage and time-sensitive pregnancy emergencies, and be ready for both maternal stabilization and neonatal priorities.
6. Mental Health Emergencies
Suicidal or homicidal ideation, aggressive behavior, anxiety, depression, bipolar and psychotic disorders, plus intentional overdose and ingestion.
Study lens: Start with immediate safety, assess intent and means directly, consider medical mimics, and choose the least restrictive safe intervention.
7. Medical Emergencies
Anaphylaxis, hematologic disorders, electrolyte and fluid problems, endocrine emergencies, immunocompromise, sepsis, hypovolemic or distributive shock, substance use, and withdrawal.
Study lens: Find the physiologic threat behind the lab value or symptom cluster, intervene, and reassess. This domain rewards pattern recognition with priorities attached.
8. Musculoskeletal and Wound Emergencies
Fractures, dislocations, amputations, compartment syndrome, tendon and ligament injuries, inflammatory conditions, osteomyelitis, complex wounds, infection, bleeding, and injection injuries.
Study lens: Document neurovascular status, recognize limb threats, control bleeding, protect tissue, and do not let a dramatic wound hide a more dangerous injury.
9. Head, Eye, Ear, Nose, Throat Emergencies
Maxillofacial infection and trauma, ocular injury or vision-threatening disease, vestibular dysfunction, foreign bodies, epistaxis, ear infection, epiglottitis, and peritonsillar abscess.
Study lens: Protect airway and vision, identify time-sensitive pressure or vascular problems, and know which “small” complaint cannot safely wait.
10. Environment and Toxicology Emergencies, and Communicable Diseases
Burns, temperature emergencies, submersion, electrical and chemical injury, bites, selected toxic exposures, and communicable diseases requiring prompt recognition and appropriate precautions.
Study lens: Stop ongoing exposure, support physiology, choose the right antidote or decontamination approach when indicated, and protect staff and other patients.
11. Professional Issues
Triage, mass-casualty care, throughput, consent, federal regulations, forensic evidence, end-of-life care, continuity, cultural humility, abuse and neglect, impaired practice, diversion, and workplace violence.
Study lens: Treat this as a clinical domain, not administrative garnish. Prioritization, safety, ethics, and legal responsibilities change what the nurse should do next.

How hard is the CEN exam?
There is no single official “difficulty score.” The exam can feel challenging because it asks an emergency nurse to reason across the full specialty under time pressure—not because every question is designed as a trick.
The scope is broad
Your assignment does not reliably deliver all 11 domains in blueprint proportions. The exam can.
Priority matters
Knowing what is true is not always enough. You must decide what matters first and what the nurse should do next.
Choices can all sound plausible
The work is often distinguishing the best response from answers that are reasonable, but late, incomplete, or aimed at the wrong threat.
Exposure is uneven
A strong adult ED nurse may need more pediatrics or obstetrics; another nurse may need toxicology, trauma, or professional issues.
The practical takeaway: Do not measure readiness by whether a topic feels familiar. Measure it by whether you can recognize the key cue, state the priority, choose an action, and explain why the other tempting answers are not first.
How should you study for the CEN exam?
Build your plan around retrieval, decisions, rationales, and repeated contact with weak domains. Rereading has a place. It just should not be asked to do the whole job.
Start with the blueprint
Use the July 2026 outline as the table of contents for your preparation. Study time should reflect both domain weight and your actual weak areas.
Take a mixed baseline set
Answer questions before you feel fully ready. A diagnostic set shows what you can retrieve and apply—not what looked familiar while you were reading.
Use active recall
Close the source and reconstruct the finding, priority, intervention, or rationale from memory. The effort is part of the learning.
Study every rationale
For each item, identify why the correct answer is best, why every distractor is wrong or lower priority, and which cue should trigger the decision next time.
Space the weak material
Return to missed concepts over several sessions instead of compressing them into one long review. Revisit before the memory feels fully comfortable.
Finish with mixed practice
Once domain gaps are smaller, mix subjects and practice switching between them. That is closer to the cognitive work of the real exam.

Common questions from CEN candidates
How much does the CEN exam cost in 2026?
As of September 25, 2026, BCEN lists the initial CEN exam at $380 for standard individual self-pay, $285 for ENA members, and $195 for eligible military applicants. Optional Test Assurance costs $70 more. Confirm current pricing with BCEN before applying.
How many questions are on the CEN exam?
The current CEN exam has 175 total items: 150 scored items and 25 unscored pretest items. The official July 2026 content outline distributes the 150 scored items across 11 domains.
What score is required to pass the CEN?
BCEN’s current CEN FAQ states that candidates must answer 99 of the 150 scored items correctly. The passing result is based on your raw number correct and is not curved against other candidates.
How long is the CEN exam?
BCEN allows 180 minutes, or three hours, for the exam. Current policy permits up to two breaks of no more than 10 minutes each, but the exam clock continues to run during breaks.
How long should I study for the CEN exam?
BCEN does not prescribe a study duration. Nurscience recommends choosing a timeline long enough to take a baseline set, review every domain, revisit weak material more than once, and complete mixed practice. A structured six-week plan is a practical starting point for many working nurses, but your baseline and schedule should set the pace.
Is the CEN exam difficult?
The CEN covers a wide range of emergency-nursing content and often asks for the best priority or next action among plausible choices. Its difficulty depends partly on your breadth of clinical exposure and how well you can apply knowledge under time pressure. Nurscience does not use an invented “difficulty percentage.”
Can I take the CEN if I do not currently work in an ER?
Yes, if you meet BCEN’s licensure requirement. A current, unencumbered or unrestricted RN license is required. BCEN recommends two years of specialty experience, but it does not require current ER employment or two years of experience to sit for the exam.
How soon can I retake the CEN if I do not pass?
BCEN currently requires a 90-day wait after an unsuccessful attempt. Unlimited retesting is allowed when the waiting period and application requirements are met. A discounted standard retest fee is available for applications made within one year of the initial exam date.
How often does CEN certification need to be renewed?
CEN certification is valid for four years. BCEN currently permits recertification by continuing-education attestation or by retaking the exam. Review BCEN’s current recertification requirements well before your expiration date.
