Which of the following is a limitation of using IQ tests to determine giftedness?

The choice highlighting that using only the full scale cutoff score of 130 may fail to identify many "gifted" students is significant because it addresses a critical limitation of relying solely on a fixed score to define giftedness. Giftedness is a broad and complex construct that encompasses not only IQ but also creativity, motivation, and special talents. Many individuals who display exceptional abilities may not meet the arbitrary cutoff score due to various factors, such as cultural influences, test anxiety, or even socioeconomic status.

By focusing exclusively on a specific cutoff, educators might overlook students who possess unique strengths or demonstrate gifted potential in ways not captured by traditional IQ testing. Such an approach risks denying these students access to programs and services that could nurture their abilities, thus limiting their educational opportunities and growth. It emphasizes the need for a more holistic assessment strategy that takes into account multiple criteria beyond a single numerical score, ensuring that all gifted students receive the support they need to thrive.
