CEN Content Outline (July 2026): The 11 Areas, Item Counts, and What Changed From 2022

The 11 CEN content areas in force since July 6, 2026

BCEN's CEN Examination Content Outline, marked "Effective July 2026," came out of the 2025 emergency nursing role delineation study. BCEN's announcement of the update gives the start date: July 6, 2026. Every CEN appointment since then uses it.

The outline assigns all 150 scored items to 11 areas. The exam has 175 items in total; BCEN's CEN FAQ says the other 25 are unscored pretest items, and the outline does not place them in any area.

The percentages are Passy's arithmetic; BCEN publishes item counts, not percentages. The full topic lists are in the outline PDF, which BCEN links from its study and prepare page.

Two things the table makes visible. First, the spread is narrow: the largest area has 18 items and the smallest 10, so no single system dominates. Second, trauma has no area of its own. The outline names cardiovascular, respiratory, gastrointestinal, genitourinary, gynecological and obstetric trauma inside their areas, plus head and spinal cord trauma, maxillofacial trauma and ocular trauma, and most musculoskeletal and wound topics are injuries. You can see how planned CEN practice is split across the same 11 areas, area by area.

Old vs new: the January 2022 and July 2026 CEN outlines side by side

BCEN still hosts the outline effective January 2022, which is useful only for comparison. It had 10 areas, also adding up to 150 scored items.

BCEN's announcement names three structural changes: Gastrointestinal became a separate section, Maxillofacial and Ocular Emergencies was "renamed and reorganized" as Head, Eye, Ear, Nose, Throat Emergencies, and Professional Issues was reorganized into two sub-sections, Prioritization (Triage, Mass Casualty, and Patient Throughput) and Legal and ethical issues.

Reading the counts together (Passy's arithmetic): the territory of the old combined area grew from 18 items to 24 across its two new areas, Mental Health gained 2 items and Medical gained 1. Every other area lost 1 or 2.

CEN topics that moved, appeared or dropped off the lists

Comparing the two PDFs line by line shows changes BCEN's summary does not spell out:

• Renal failure was listed under Medical Emergencies in 2022 and now sits under the genitourinary part of the Genitourinary, Gynecology, and Obstetrical area
• Ear, nose and throat topics were folded into "Maxillofacial" in 2022. The HEENT area now has its own Ear, Nose and Throat headings: epistaxis, peritonsillar abscess and acute vestibular dysfunction moved under them, and ear and nose foreign bodies, ear infections and epiglottitis are now named topics (in 2022, otitis appeared only as an example of maxillofacial infections)
• Newly named topics include croup (Respiratory), myocarditis (grouped with endocarditis and pericarditis), uterine rupture (Obstetrical), gastrointestinal disorders, and sexually transmitted infections (Communicable Diseases)
• Changed headings: influenza is now listed as respiratory viruses, and the 2022 mental health headings for mood disorders and thought disorders were replaced by depressive disorders, bipolar disorders and psychotic disorders
• No longer named: acute abdomen (Gastrointestinal), situational crisis (Mental Health), envenomation emergencies (Environment; animal bites remains)
• Professional Issues went from four groups (Nurse, Patient, System, Triage) to two. Prioritization holds triage, mass casualty and patient throughput. Legal and ethical issues lists end-of-life and palliative care, forensic evidence collection, federal regulations, patient consent for treatment, continuity of care, cultural humility, abuse and neglect, impaired nurse and drug diversion, and workplace violence. Several 2022 headings, such as pain management and procedural sedation, discharge planning, delegation, disaster management and patient satisfaction, are not named in the 2026 list

A topic that left a list is a lower priority, not proof it can never appear inside another scenario: BCEN's outline names topics but does not publish item-level detail. Most clinical headings appear in both outlines, so older clinical review is not wasted. What is out of date is the area structure, the item counts and the way Professional Issues is organized.

The CEN passing score changed with the outline

The update also came with a new passing standard. BCEN's announcement lists "Updated CEN Passing Score: 99/150 questions" with the same effective date, July 6, 2026, and the current FAQ repeats 99 of the 150 scored items. Before that date, BCEN's FAQ listed 106. The CEN passing score guide explains how the new number was set and why it is not a percentage.

How to tell whether your CEN materials match the current outline

Check any book, course or question bank against four signs of the July 2026 outline:

1. Eleven areas, with Gastrointestinal Emergencies separate from Genitourinary, Gynecology, and Obstetrical Emergencies
2. A HEENT area instead of "Maxillofacial and Ocular"
3. Professional Issues with Prioritization and Legal and ethical issues rather than Nurse, Patient, System and Triage
4. A passing score of 99 of 150, not 106

If a resource shows 10 areas or 106, it was built for the January 2022 outline. Several prep websites checked on October 27, 2026 still quote 106. That doesn't make their clinical review useless, but don't use their area weights or score targets. Full CEN prep planned for launch tags every question to a July 2026 area, so 2022 groupings are not mixed in.

As of October 27, 2026, BCEN's CEN pages announce no further outline change, so a candidate testing in 2027 will use this outline unless BCEN announces otherwise.

Turning the CEN item counts into study time

Item counts are the simplest guide to where study hours go. A 10-item area still carries 6.7% of the score, and the two 10-item areas together carry more than Cardiovascular alone. The CEN study plan turns the counts into an 8-week schedule, and the free CEN study planner builds an outline from your exam date and daily study time, weighted by the same 11 areas.

To find your weakest area before you commit hours, try the 20 free CEN practice questions, which are split across the 11 areas roughly in proportion to their item counts. Twenty items can't predict a score, but they show where your reasoning slips. When you know your test month, compare the planned 30-, 90- and 180-day CEN access periods; checkout is not open yet.
