What is the value of including substance use in the test?

• A. It helps assess reliability and risk tendencies that could impact on-the-job integrity.
• B. To test general knowledge of substances.
• C. To compare applicants against policies.
• D. To evaluate personal preferences.

Answer: (A)

Including substance use in the test targets how likely someone is to engage in risky or disallowed behavior that could undermine reliability or safety on the job. These items are meant to reveal attitudes toward rules, self-control, and potential impairment, which relate directly to on-the-job integrity. It’s not about factual knowledge of substances or policy details, but about behavioral tendencies that can predict performance and conduct at work. The other options miss this predictive purpose: general knowledge of substances isn’t what’s being measured, comparing applicants against policies isn’t assessing behavior or risk, and evaluating personal preferences isn’t a reliable indicator of work conduct.
