CEN Exam Format: 175 Questions, 150 Scored, and 180 Minutes at PSI or Online

The CEN exam format at a glance

Every CEN exam has 175 questions, and 150 of them count. BCEN's CEN FAQ describes the other 25 as "unscored pretest items" and does not identify them, so treat every question as if it counts. Here is the full shape of the sitting, as checked on October 27, 2026:

The CEN content outline guide breaks down the 11 areas, and the CEN passing score guide covers the 99-of-150 standard. Both delivery methods give the same exam: BCEN's candidate handbook says exams delivered by remote proctoring "are the same as those delivered in a test center and have the same level of exam security."

What CEN questions look like

BCEN publishes 10 CEN sample questions to show the format. Each is a single question with four answer choices and one preferred response. Most open with a short patient situation, and many ask for the most critical finding, the priority action or question, or the best placement after triage, with words such as MOST, PRIORITY and BEST in capitals. BCEN says the samples show "how questions reflect the nursing process" and are not meant to reflect the difficulty of the real exam. The BCEN pages checked for this guide don't describe any other question type.

Behind the questions, BCEN's About the Exam page describes the process: nurse item writers create the items, an exam construction and review committee reviews, revises and approves them, and the exam committee sets the "cognitive level distribution" and the number of items per area. BCEN does not publish that distribution. During the exam you can click a Comment button on a question; the handbook says comments are reviewed by the committee, but you won't get an individual reply. To get used to four-option, priority-style items before test day, planned CEN practice lets you drill one content area at a time, with an explanation for every answer.

CEN pacing: about a minute per question

Some Passy arithmetic. 180 minutes for 175 questions is about 62 seconds per question if you take no breaks. Two full 10-minute breaks leave 160 minutes, or about 55 seconds per question. Since you can't tell the pretest items apart, pace for all 175.

At that pace, one item that stalls you for five minutes costs the time of about five others. If you want to rehearse the rhythm under the real clock, a timed 175-question CEN mock exam is planned for full prep, and the free CEN practice questions let you check your reasoning on 20 original items now.

Breaks during the CEN: the clock keeps running

The handbook allows up to two breaks, whenever you wish, but gives no extra time for them. Each break must not exceed 10 minutes; a longer break gets you removed from the exam. During a break you may not access personal items other than medication you need at a specific time, unless you received permission in advance. At a test center you show ID when you leave and re-enter the room. With remote proctoring you tell the proctor, the exam is not paused, and you repeat the room sweep when you return.

PSI test center or Live Remote Proctoring for the CEN

BCEN's exam delivery page compares the two options. You choose when you schedule with PSI after BCEN processes your application, and you can switch later by rescheduling.

For remote testing, BCEN's Live Remote Proctoring page asks you to run PSI's compatibility check before you schedule and again 72 hours before the exam, and to complete PSI's exam tutorial at least 3 days ahead. You need a webcam you can move for the room scan, a working microphone and speakers, and a stable broadband connection. The handbook adds that your hands must stay visible to the camera and that talking or mouthing words is prohibited. The LRP page says the proctor will end the exam after up to three minor infractions or one major infraction, with no refund and a 90-day wait before a new application.

ID and check-in rules that can cost you the CEN fee

The handbook and BCEN's apply and schedule page set these rules:

• One ID, matching exactly. Bring a valid, unexpired government-issued ID with your name, photo and signature. The first and last name you registered with must match the ID exactly
• No ID means a missed appointment. Failing to supply proper ID is treated as a missed appointment, with no refund of the exam fee
• Where the ID is from. IDs must be issued by the country you test in; otherwise you need a passport from your country of citizenship. Military IDs are not accepted for remote proctoring
• Photograph. You must agree to have your photo taken, or you won't be admitted
• Late arrival. If you are late, you may be denied admission and forfeit the fee
• No devices. Phones, cameras and other electronic or recording devices are not allowed in PSI test centers or, for remote testing, anywhere in your testing session except your testing computer

Rescheduling, refunds and the 90-day testing window are covered in the CEN eligibility and application guide. One point belongs here because it differs by delivery method: BCEN's FAQ and handbook allow free rescheduling with 24 hours' notice (its rescheduling policy says "more than 24 hours"), while its Live Remote Proctoring page says at least 48 hours for remote exams. BCEN's pages don't reconcile the two, so plan on 48 hours to be safe.

When CEN results appear

At a test center, the administrator gives you a written score report moments after you finish, and a copy arrives by email. With remote proctoring, a PASS or FAIL screen appears when you finish, and a more detailed report follows by email. Score reports show whether you passed, and the handbook says they include a breakdown by major content area.

Practicing for the CEN format before you book

Once you know the format, the next decision is when to test. The free CEN study planner spaces the 11 areas across the weeks you have, and you can check what full CEN prep will include before you pick a test date; it is listed as "At launch," and checkout isn't open yet.
