How many secondary indexes are in the WISC?

• A. Four
• B. Six
• C. Five
• D. Seven

Answer: (C)

Secondary indexes on the WISC are the two supplementary composite scores that provide additional ways to interpret a child's cognitive profile beyond the primary index scales. There are two of these: the General Ability Index, which combines Verbal Comprehension, Visual Spatial, and Fluid Reasoning, and the Cognitive Proficiency Index, which combines Working Memory and Processing Speed. These indexes help clinicians view overall reasoning and cognitive efficiency separately from the Full Scale IQ, especially when working memory or processing speed might be affecting the overall score. The WISC-V features five primary index scales (Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, Processing Speed) alongside these two secondary indexes, giving seven index scores available for interpretation.
