What age group is the Wechsler Intelligence Scale primarily designed for?

The Wechsler Intelligence Scale is primarily designed for children and is most commonly used for individuals aged 6 to 16 years old. This age range is significant because it encompasses a critical developmental period where cognitive abilities can be accurately assessed and observed. The scale is tailored to evaluate various intellectual capabilities in children within this bracket, including verbal comprehension, perceptual reasoning, working memory, and processing speed.

Using this specific age group allows educators, psychologists, and other professionals to understand the intellectual functioning of children in a variety of contexts, helping to inform educational strategies and interventions suitable for their developmental stage. Other age groups presented in the question do not align with the core design and purpose of the Wechsler Intelligence Scale.
