When selecting tests for children versus adults, which consideration is essential?

• A. Use the same adult norms for both groups.
• B. Developmental norms are not necessary if the test is reliable.
• C. Use age-appropriate, developmentally validated instruments with appropriate norms.
• D. Language and cultural factors can be ignored if standardized.

Answer: (C)

When assessing children versus adults, you need tests that are matched to the person’s developmental level and have norms built from similar-age groups. Developmental stages shape what abilities are expected and how tasks are performed, so a child’s score must be interpreted against peers of the same age. Instruments that are developmentally validated include age-appropriate items and separate normative data, which allows meaningful comparisons and accurate conclusions about a child’s functioning relative to their developmental stage. Reliability is important, but it doesn’t substitute for appropriate norms; a test can be reliable yet invalid for a given age if its items and scoring aren’t designed for that developmental level. Language and cultural factors also matter, and they should be considered so results reflect true ability rather than language or cultural biases.
