An individually-administered instrument, as compared to a group-administered instrument, has the advantage of:

• A. Allowing the administrator to observe nonverbal behaviors.
• B. Requiring less time.
• C. Lower cost.
• D. Eliminating interpretation.

Answer: (A)

Observing nonverbal behavior is the main advantage of individually administered assessments. In a one-on-one setting, the examiner can watch cues such as facial expressions, posture, eye contact, and signs of effort, anxiety, or confusion. These nonverbal signals can illuminate how the person is engaging with items, whether instructions are clear, or if there’s defensiveness or confusion that might color responses—insights you can’t reliably capture in a group setting. The one-on-one format also lets the tester tailor prompts, rephrase questions for clarity, and probe for depth, which is much harder when many students are completing items at once and time is constrained. Because of these interactive dynamics, individual administration is typically more time-consuming and resource-intensive, and interpretation remains a central task in any assessment context. So, while group administration can be faster and cheaper, and interpretation is still needed in both formats, the distinct benefit of individual testing lies in the opportunity to observe and respond to nonverbal behavior.
