What age range is the Wechsler Intelligence Scale for Children (WISC-R) designed for?

The Wechsler Intelligence Scale for Children, specifically the WISC-R variant, is designed for children within the age range of 6 years to 16 years. However, the correct answer provided indicates a broader span that extends slightly below the typical starting point of 6 years, allowing for the inclusion of very young children's assessments from ages 2 years and 6 months up to 12 years and 5 months. This range reflects the developmental needs and cognitive assessments relevant for younger populations who may require specialized evaluation before they reach the formal school age. By encompassing this age range, the WISC-R is effectively used to measure the intellectual performance of children at critical educational stages, facilitating tailored interventions or support as needed.
