1.2 Format, Delivery, and Time Rules

The current exam appointment

The current CHES exam contains 165 four-option multiple-choice items. Of those, 150 are scored and 15 are pilot (pretest) items used for future exam development. Candidates are never told which items are pilots, so every question deserves a full, normal attempt. The operating rule is simple: answer each item as if it counts, because you cannot identify which ones feed the scaled score.

Candidates are allotted a total of 3 hours to complete the exam, and the optional 10-minute break between blocks is counted inside that 3 hours — it is deducted from your total testing time, not added on top. There is no separate longer appointment window for the questions themselves, so plan every pacing decision against a single 3-hour clock. On test day you should also expect a short, untimed tutorial before the clock starts and an end-of-exam survey afterward, but your pacing math must fit 165 items into 180 minutes.

Delivery channels

NCHEC delivers the exam through the vendor PSI. You may choose an onsite PSI test center or PSI Live Remote Proctoring taken from home. After NCHEC approves eligibility, you receive authorization to schedule through PSI.

The channel does not change your content preparation, but it changes your logistics. The goal is to keep administrative stress from draining attention before the first item loads.

Pacing the 165 items

Three hours equals 180 minutes. If the 10-minute break is used, roughly 170 minutes remain for questions, which is about 1.0 minute per item — a little over a minute if you skip the break. That average is a budget, not a rule: pure recognition items may take 20 seconds, while a layered scenario that requires sorting four plausible distractors may take two minutes. Build that variance into practice with timed mixed sets so you can move quickly without rushing the scenarios that actually decide your score.

Use a three-pass system inside each block:

1. First pass — answer everything you can resolve with confidence; mark only the genuinely uncertain.
2. Second pass — return to marked items where you narrowed it to two options and compare against the exact task in the stem.
3. Third pass — commit an answer to every remaining item before the block closes.

Because there is no penalty for guessing, never leave an item blank. If unsure, eliminate options that are clearly out of sequence, outside the health education role, ethically weak, or unsupported by the data, then pick the best of what remains.

Pilot items and test behavior

Pilot items may feel easier, harder, or simply unusual, but do not spend exam time trying to detect them — that creates distraction and wrecks pacing. Treat odd wording as normal: read the stem, identify the professional task, and choose the option that fits the eight Areas and the program stage described.

Practice should mirror the format exactly: four-option items, scenario stems, and explanations that force you to say why the key beats each distractor. Flashcards can build vocabulary, but they do not rehearse the applied judgment the exam rewards under a clock.

Scenario review checklist

• Identify the relevant CHES Area of Responsibility.
• Locate the program stage described in the scenario.
• Match the answer to evidence, stakeholders, and ethics.
• Reject choices that are premature, unsupported, or outside the entry-level role.

Test-day logistics that protect your score

Format knowledge only helps if administrative friction does not eat your attention. Plan the hours before the exam with the same care as the content.

Identification. PSI requires a current, government-issued photo ID whose name matches your registration exactly. A nickname, a missing middle name, or a recently changed surname can cost you the appointment with no refund. Confirm the spelling on your NCHEC application matches your ID weeks ahead, not on test morning.

For a test center. Arrive early — typically 30 minutes before the appointment — to allow for check-in, ID verification, a security scan, and storage of personal items. You will be assigned a workstation; scratch paper or a digital whiteboard and a basic on-screen calculator are usually provided, and personal notes, phones, smartwatches, and bags are prohibited in the testing room.

For PSI Live Remote Proctoring. Run the system check days in advance, not minutes before. Test your webcam, microphone, and internet speed; clear your desk; remove second monitors; and choose a private, quiet, well-lit room. The proctor will ask you to show the room and your ID by camera, and a phone ringing or a person entering can pause or void the session.

What to expect on screen

Learn the navigation in the tutorial so you are not discovering the mark and review buttons during Block 1. Every minute you spend fumbling controls is a minute taken from scenario reasoning. A calm, rehearsed logistics plan converts your format knowledge into actual answered items.
