A case study from Connecticut illustrates the practical use of IQ testing in identifying underlying issues for students. A 14-year-old named Candace was failing all her ninth-grade classes and exhibited significant behavioral problems, including fighting and cursing at teachers. A court-ordered psychological evaluation, which included an IQ test, revealed her score to be 68. This score provided a crucial insight, suggesting that her struggles in school were likely linked to an intellectual disability that had previously gone unnoticed, rather than being solely behavioral.
