1.2 Format, Delivery, and Time Rules

The 175-question format for the next CHES cycle

For Spring 2027, NCHEC's current CHES exam page and background/scoring page specify 175 multiple-choice questions: 150 scored and 25 unscored pilot items. Candidates are not told which items are pilots. Answer the examination normally instead of trying to identify the unscored questions by their difficulty or wording.

NCHEC confirms three testing hours, equivalent to 180 minutes, including an optional ten-minute break. The current question blocks are:

There are 88 questions in the first question block and 87 in the second, for 175 altogether. The word “block” also names the intervening break on NCHEC's page; it does not mean there are three sets of scored questions. Follow the displayed timer and instructions rather than inventing a separate fixed time allowance for each question block.

Historical format and current appointment activities

The completed October 2026 HESPA II examination had 165 items: 150 scored and 15 pilot. Its question blocks were 1–83 and 84–165. Those are historical numbers, not the block boundaries for the upcoming 175-item exam.

NCHEC's currently linked CHES Exam Handbook, October 2026, pages 6 and 21, describes the 175-item format and permits a maximum appointment of three hours and thirty minutes at a PSI test centre or through live remote proctoring. That is an appointment limit, not 3.5 hours for answering questions. The introductory tutorial has a separate ten-minute allocation; the question activity has 180 minutes; the satisfaction survey and completion notice have an estimated allocation of less than ten minutes.

The handbook says these appointment activities are timed separately: unused tutorial minutes do not roll into testing, and unused testing minutes do not enlarge the closing activities. The maximum appointment is not a promise that every activity will consume a fixed duration. Follow the displayed activity timer, any approved accommodation and your current appointment instructions.

Delivery choices

NCHEC offers PSI test centres and PSI live remote proctoring. Eligibility approval and the Authorization to Test come before appointment scheduling. Confirm that your chosen delivery option is available and that you can meet its requirements.

The delivery option changes logistics, while the same CHES blueprint guides your content preparation. Resolve administrative and equipment questions before the appointment so you can devote the testing clock to the examination.

Pacing 175 items within the actual testing clock

Three hours is 180 minutes. With no break used, that is an overall average of 180 ÷ 175 = about 1.029 minutes, or 61.7 seconds per item. Taking the full optional ten-minute break leaves 170 minutes, about 0.971 minutes or 58.3 seconds per item, for answering and reviewing questions within that allocation. These are planning averages, not a maximum time imposed on each question.

A short recognition question and a layered scenario may need different amounts of time. Practise a mixture so that faster responses create room for decisions requiring more reading. Keep explanation review outside a timed rehearsal; otherwise the rehearsal no longer measures your ability to answer within the actual testing clock.

Review within the question block that is still accessible

Use the review functions provided in the actual interface and its tutorial. A practical routine is:

1. Answer items you can resolve from the facts and identify those that need reconsideration.
2. Revisit uncertain responses while the current question block remains accessible, comparing each choice with the exact task and constraints in the stem.
3. Resolve remaining answers before leaving the block, using elimination when necessary.

NCHEC expressly allows checking/changing first-block answers before that block is completed. Once you enter the third platform block, containing questions 89–175, you cannot return to questions 1–88. Do not plan to repair a first-block answer during the second question block.

The scoring page says there is no penalty for guessing. Within the available controls and time, provide an answer to each item rather than leaving a response blank merely because you are uncertain. Elimination should be based on the scenario: an unsupported assumption, a task at the wrong stage or an ethical problem can distinguish an option without requiring you to know which items are pilots.

Pilot questions and useful practice

The 25 pilot items do not contribute to the final score and are not identified to candidates. Difficulty is not a reliable identifier: a scored item can be challenging and a pilot can be straightforward. Spend your time answering the professional question rather than guessing its status.

Independent practice should combine factual retrieval with cases and clear explanations. Our practice questions can use four options, but a useful exercise also asks why the chosen option fits and why the alternatives fail. Flashcards support retrieval; a timed mixed set additionally tests reading, sequencing and pacing.

A correction checklist

• Identify the relevant responsibility and the decision requested.
• State what the scenario has already established and what remains unknown.
• Check population, evidence, resources, authority and ethics.
• Distinguish a content error from a calculation, reading or pacing error.
• Rework the example before the next timed set.

A timed score alone does not identify the cause of a mistake. Keep a short correction note so that the next session addresses an actual learning need.

Prepare the appointment as carefully as the content

Start with the Authorization to Test and your appointment confirmation. Confirm the date, time, time zone, delivery mode and legal name in the NCHEC/PSI record. Resolve a name change with the responsible organization in advance rather than assuming a nickname or altered surname will be accepted at check-in.

Test-centre preparation

The currently linked CHES Exam Handbook, page 23, requires original, unexpired government-issued photo identification bearing a signature, with the name exactly matching the Authorization to Test. Use the accepted documents in your instructions; an informal substitute is not enough. Arrival instructions differ within this current handbook: page 16 asks candidates to arrive at least thirty minutes early for both test-centre and live-remote appointments, while page 23 says at least fifteen minutes early for test-centre check-in. Plan to be ready at least thirty minutes before your appointment, or earlier if your confirmation requires it. Confirm any unclear directions with NCHEC/PSI; do not infer a late-arrival grace period.

Confirm travel, parking and building access. NCHEC's test-centre page describes a computer-based calculator and storage for personal belongings, with access restrictions during testing. Do not assume that personal notes, a phone or your own calculator may be used because an on-screen tool is available. Follow any approved accommodation and the centre's actual directions for permitted items.

Live remote proctoring preparation

Use NCHEC's current remote-proctoring information and PSI's linked technical requirements. Check the computer, browser, camera, microphone, connection and environment well before the appointment. A successful basic compatibility check is not a substitute for meeting every published system and testing-room requirement.

If you use an employer- or school-managed device, resolve installation and permission issues with its administrator in advance. Prepare the contact instructions provided for technical problems. Do not assume an unapproved device change, backup connection or assistance from another person is permitted during a live session.

Use the tutorial and the stated block rules

Arrange needed accommodations before scheduling through the NCHEC/PSI process described in your current instructions. A test-centre employee cannot be assumed to approve a new arrangement on exam day. Keep the approval and any special scheduling instructions with your preparation checklist.

Finally, prepare a simple pre-exam routine: identification and confirmation ready, travel or room checked, and enough time to complete check-in calmly. This does not guarantee an outcome, but it reduces the number of administrative decisions competing with your attention during the exam.
