How many subtests are used to calculate FSIQ using the WISC?

• A. 8
• B. 10
• C. 12
• D. 14

Answer: (B)

FSIQ on the WISC is computed from ten core subtests that span verbal ability, working memory, perceptual reasoning, and processing speed. Using these ten subtests ensures the FSIQ reflects performance across multiple cognitive areas rather than a single task. Verbal contributions come from Similarities, Vocabulary, and Information; Working Memory from Digit Span and Letter-Number Sequencing; Perceptual Reasoning from Block Design, Matrix Reasoning, and Visual Puzzles; and Processing Speed from Coding and Symbol Search. The scores from these subtests are combined to produce the Full Scale IQ. There are additional subtests available for supplemental information, but they do not change the FSIQ under standard scoring.
