Intelligence progresses in measurable and predictable stages and IQ tests are used to test basic intellectual functioning, such as conceptual thinking, language, and problem solving. The IQ test is used to diagnose developmental disabilities as well as learning disabilities and intellectual disabilities in schools. School aged children may be given an IQ test to determine eligibility and placement for special education services and to pinpoint specific deficits and/or strengths. Part of the strength of using IQ tests is their ability to predict specific attributes, such as academic skills and adaptive skills. However, these correlations change with the child’s age. Understanding these predictions can help eligibility determination, particularly for learning disorders. The purpose of this study was to investigate these changing IQ/achievement predictions in 150 school-aged children, all of whom were referred for special educational testing. Correlations and multiple regression were used to test the hypotheses.
