The CEN has one of the lower pass rates on the board (overall results often land near 50% once retakes are counted) which means walking in 'experienced but unprepared' is a common, expensive mistake. Here's how to actually pass the first time.

About the credential
The CEN certifies expertise in emergency nursing, from triage and trauma to cardiovascular, respiratory, neuro, and toxicologic emergencies across the lifespan. It's a knowledge-broad exam, and strong bedside ED nurses still fail it by underestimating the breadth; a question-bank-driven plan that forces you across every domain is what closes the gap.
Who pursues it
Emergency department RNs pursuing specialty certification
ED nurses chasing clinical-ladder advancement or differentials
Nurses moving into emergency from urgent care, flight/transport, or critical care
Does the CEN actually raise your pay? (The honest answer)
~60%
of nurses got no direct pay bump for certifying
$1–2/hr (~$2,000–4,000/yr full-time)
typical raise when employers do pay
$1,000–2,000 one-time at some employers
one-time bonus where offered
Worth saying plainly: in a large national compensation survey, about 60% of nurses got no direct pay increase for certification. When the CEN does pay, it's typically $1–2/hr or a one-time bonus, and that's your employer's call, not BCEN's or the state's. The 'certified nurses earn more' stat mostly reflects that they're also more experienced. The CEN is a respected ED credential; just go in with realistic pay expectations.
When it's worth it anyway
Your ED has a clinical-ladder program or certification differential; ask HR for the exact amount first.
It's required or preferred for a charge, trauma, flight/transport, or Magnet-facility role you want.
You're using it as a resume differentiator to move into emergency from another specialty.
You want the broad knowledge and confidence for your own practice, a valid non-financial reason.
No mandatory hours, but BCEN recommends ~2 years of emergency nursing experience before sitting

A study plan that works
1Weeks 1–2: Get the BCEN CEN Exam Content Outline and map your plan to its domains: cardiovascular, respiratory, neurological, gastrointestinal/genitourinary/gynecology/obstetrical, psychosocial and medical, maxillofacial/ocular/orthopedic/wound, environment/toxicology/communicable disease, and professional issues. The overall pass rate (~50% including retakes) means structured prep matters, so take a diagnostic set early, because breadth is the trap.
2Weeks 1–6: Make a question bank the spine of your prep. CEN items reward rapid prioritization and triage thinking, not just recall: 30–50 a day, and review every miss including why each wrong option is wrong.
3Weeks 1–3: Front-load Cardiovascular and Respiratory, the highest-yield domains: ACS and 12-lead, dysrhythmias, cardiac arrest and ACLS, shock; airway management, respiratory failure, pulmonary embolism, pneumothorax, and asthma/COPD.
4Weeks 2–4: Neurological and resuscitation: stroke (and thrombolytic windows), seizures and status epilepticus, altered mental status, increased ICP and head trauma; ACLS/PALS algorithms, RSI, and post-resuscitation care.
5Weeks 3–5: Trauma and the mechanical domains plus the medical mix: multisystem trauma and the primary/secondary survey, maxillofacial/ocular/ENT/dental, orthopedic and wound care; then sepsis, endocrine and electrolyte emergencies, GI bleed, renal/GU, and obstetric and gynecologic emergencies.
6Weeks 4–6: Hit the domains ED nurses under-study because they see them less: toxicology and overdose (antidotes), environmental emergencies (heat/cold, bites/stings, drowning), communicable-disease precautions, plus psychosocial/behavioral emergencies and professional issues (EMTALA, triage systems, forensic evidence, patient safety).
7Weeks 7–8: Switch to timed, mixed-domain sets to build stamina for 175 questions in 3 hours and rehearse pacing (~60 seconds per question).
8Final week: Consolidate, don't cram. Work your error log and a triage/ACLS/antidote quick sheet, taper new material, confirm testing logistics, and protect your sleep.
9Throughout: Keep one error log. Every missed question goes in it with why you missed it; reviewing it in the final week is the highest-return study activity.

Which exam to take
CEN is the emergency-nursing generalist credential; TCRN (also BCEN) is trauma-specific. If you work general ED, take CEN; if you're trauma-focused, TCRN may fit better. Many ED nurses pursue CEN first.
Keeping it current
CEN renews every 4 years through continuing education or by retaking the exam. Confirm the current renewal pathways and CE category requirements with BCEN.
Frequently asked questions
Why is the CEN pass rate so low?
The exam is broad (it spans every emergency domain across the lifespan) and many experienced ED nurses underestimate that breadth and study only their strong areas. Overall pass rates (including retakes) often sit near 50%, which is exactly why a blueprint-mapped, question-bank-driven study plan matters.
Do I need a certain number of hours to take the CEN?
BCEN doesn't mandate a specific hour count, but it recommends about two years of emergency nursing experience before sitting. Confirm current eligibility with BCEN.
CEN vs TCRN: which should I take?
CEN is the emergency generalist certification; TCRN is trauma-specific. Match it to your practice: general ED nurses usually take CEN first; trauma-focused nurses may prefer TCRN.
What's the best CEN review course?
Most nurses who pass pair a question bank with daily mobile reps, and some add a live review like Solheim's. Question-bank reps with thorough rationale review are the highest-yield component.
Does getting your CEN actually raise your pay?
Often not directly. In a large national compensation survey, roughly 60% of nurses reported no direct pay increase for certification; when employers do pay, it's typically about $1–2/hr or a one-time bonus, set by your employer rather than BCEN. The CEN is still a respected ED credential worth pursuing when your employer offers a differential or clinical ladder, when it's required or preferred for a charge/trauma/flight role, or as a resume differentiator; confirm the amount with HR first.
