11.2 Work the Two-Block Navigation Rule

Make the block boundary visible in practice

The CHES exam is divided into two question blocks. Block 1 contains questions 1-83. After that block, candidates may have an optional break before continuing to questions 84-165. Once the second question block begins, the first block is closed. You cannot rely on a final all-exam review to repair unfinished thinking from questions 1-83.

This rule is especially important for scenario items. A question may describe a school wellness coalition, a community survey, a grant work plan, or a confidentiality concern. The answer often depends on the phrase that identifies the stage of the health education process. If you mark too many items without resolving them inside the block, you create a backlog that cannot be revisited later.

Block-close checklist

Before leaving block 1, ask four questions:

• Have I answered every item from 1-83?
• Are all marked items either resolved or intentionally guessed?
• Did I check items where I changed an answer because of a single word?
• Am I ready to give up access to this block?

The optional break is also part of strategy. Official materials describe an optional 10-minute break between the blocks, and the source brief for this guide states that break time is deducted from total test time. Use the break only if the reset is worth the time. A short pause can help if your attention has dropped, but a break that creates urgency in the second block may do more harm than good.

A practical approach is to decide before test day what signals justify taking the break. For example, use it if you notice repeated misreads, physical discomfort, or mental fatigue that will likely cost more than a few minutes. Skip or shorten it if you are calm, behind pace, and able to continue accurately.

Inside each block, use the exam interface as a workflow. Mark items only when a second look is likely to change the answer. Do not mark every item that feels mildly uncertain. If you can eliminate two choices and the remaining decision is a judgment call, choose the better answer and move. Overmarking creates a false sense of control while draining review time.

The best block strategy is also an Area strategy. If an item asks what to do first, decide whether the scenario is still in Area I Assessment or Area II Planning. If it asks how to deliver a session with fidelity, think Area III Implementation. If it asks what data show success, think Area IV Evaluation and Research. These labels turn a long scenario into a structured decision.

Practice this rule before exam day by taking at least one two-block practice set. Use 83 questions, close the set, take or skip a timed break, then complete 82 more questions. The point is not to imitate official questions. The point is to train the irreversible decision at the block boundary so it does not surprise you during the appointment.
