1.2 Format, Delivery, and Time Rules

The current exam appointment

The current CHES exam contains 165 four-response multiple-choice items. Of those, 150 items are scored and 15 are pretest items used for exam development. Candidates are not told which items are pretest, so every item deserves a normal attempt. The practical rule is simple: answer each question as if it counts, because you cannot identify which items will contribute to the scaled score.

Candidates receive 3 hours of exam time. The full appointment may be up to 3.5 hours because it also includes administrative pieces such as the tutorial and survey. That distinction matters for planning. The study target is not 3.5 hours of question answering. Your pacing plan must fit the 165-item exam into the 3-hour exam-time limit.

Delivery channels

NCHEC materials identify computer-based delivery through PSI test centers and live remote proctoring through PSI Bridge. After eligibility is approved, candidates receive authorization information that allows scheduling through PSI. For a test center appointment, identification must match PSI records exactly. For a remote appointment, candidates should expect a proctored testing environment with identity, workspace, and technology checks.

The delivery channel should not change your content preparation, but it can affect your logistics plan. A test center candidate should plan travel, parking, identification, and arrival time. A remote candidate should plan a stable internet connection, quiet space, permitted materials, device setup, and any required system checks. In both cases, the goal is to prevent administrative stress from consuming attention before the first item appears.

Pacing the 165 items

Three hours equals 180 minutes. A rough working pace is a little over one minute per item across all 165 questions. That does not mean every question deserves exactly the same time. Some items are quick recognition items. Others require reading a scenario, sorting distractors, and identifying the best next step. Your practice should include timed mixed sets so you can move efficiently without rushing scenario interpretation.

A good pacing system uses three passes within each block. First, answer items you can resolve with confidence. Second, return to marked items that require comparison between two plausible options. Third, make a final selection on remaining items. Because there is no penalty for guessing, leaving an item blank is not a useful strategy. If you are unsure, eliminate what is clearly wrong and choose the best remaining option.

Pretest items and test behavior

Pretest items may feel easier, harder, or simply different, but you should not spend exam time trying to detect them. That creates distraction and can lead to poor pacing. Treat unfamiliar wording as part of the normal exam environment. Read the stem, identify the professional task, and choose the option that best fits the Eight Areas and the stage of work described.

Practice should mirror the format. Use four-option multiple-choice questions, scenario stems, and explanations that force you to say why the correct answer is better than the distractors. Avoid studying only flashcards. Flashcards can support vocabulary, but the exam rewards applied judgment under time limits.

Scenario Review Checklist

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