8.5 Diagramming Simple Conditions

Turn Rules Into Small Maps

A diagram is a short visual version of a rule. It can be as simple as an arrow, a checklist, or a two-column table. The goal is not to create art. The goal is to prevent the rule from getting lost while you compare answer choices.

Deductive Reasoning appears in Section III of the CJBAT. Section III shares 1 hour across Written Comprehension, Written Expression, Deductive Reasoning, and Inductive Reasoning. Because time is shared, diagrams should be quick. If a diagram takes longer than reading the item carefully, it is not helping.

Use arrows for if/then rules. For the official late-arrival rule, write: late arrival OR missing required materials -> no test and no fee return. The arrow shows the direction. It also reminds you not to reverse the rule.

Use checklists for rules with multiple requirements. For the official ID rule, candidates must bring two current, unexpired, signature-bearing IDs; one must be government-issued photo ID; names and signatures must match; no other materials are allowed. A checklist keeps each requirement visible.

Use side-by-side columns when a rule separates categories. Law enforcement and corrections have separate tests. The law-enforcement BAT exemption does not apply to corrections academy candidates. A two-column chart helps prevent carrying a condition into the wrong track.

Use a flow when timing matters. For retakes, the brief says candidates must wait 24 hours after a failed exam before making a retake reservation, retake reservations cannot be made at the test center, and a new examination fee is required for each retake. A flow can show failed exam -> wait 24 hours before reservation -> new fee required.

Use labels when a rule has a source. Mark same-day Pearson VUE results as unofficial and mark ATMS as the controlling record. That keeps the diagram from merging two different result concepts.

Diagram carefully:

• Keep the original rule nearby in your mind.
• Use arrows only in the direction given.
• Use checkboxes when every condition matters.
• Use columns when categories differ.
• Add no facts to the diagram.
• Return to the prompt before choosing the answer.

A diagram is a memory support, not an official source. If your diagram and the prompt seem to differ, trust the prompt. The CJBAT measures reasoning from provided material, so the best diagram is the one that accurately preserves that material in a smaller form.
