The WIAT is not used for which purpose?

• A. Measuring giftedness in older adolescents and adults
• B. Assessing math computation
• C. Measuring reading fluency
• D. Predicting IQ

Answer: (A)

The main idea here is understanding what the WIAT actually measures. The WIAT is an achievement test designed to assess what a person has learned in key academic areas—reading, math, spelling, and writing—and to help identify strengths, weaknesses, and educational needs. It’s used to gauge current skills and progress, not to gauge a person’s potential or cognitive ability.

Because giftedness is about potential or aptitude, and is typically identified with cognitive ability tests (like IQ measures) rather than achievement tests, the WIAT isn’t used to measure giftedness in older adolescents and adults. That mismatch in purpose is why this option is the best choice. The WIAT does cover reading fluency and math computation as part of achievement assessment, so those are appropriate uses.
