How many sub scales are used to form the FSIQ on the WISC?

Explanation:
Seven core subtests are used to form the Full Scale IQ on the WISC. The Full Scale IQ is a single global measure of general cognitive ability that combines performance across different cognitive domains. To create this overall score, a fixed set of core subtests is selected because they provide reliable, representative information about verbal abilities, nonverbal/problem-solving skills, working memory, and processing speed. Supplemental subtests exist for added detail or alternative interpretations, but they don’t change the seven-core-subtest basis of the FSIQ. This setup helps ensure the FSIQ reflects broad cognitive functioning rather than relying on just one area.
