Wechsler Intelligence Scale for Children – Fourth Edition (WISC-IV): Administration and Scoring Manual
Scoring the WISC-IV is a multi-step process that transforms raw performance into meaningful clinical data. First, raw scores—the simple sum of points earned on each subtest—are calculated based on the specific criteria found in the manual. These raw scores are then converted into scaled scores using age-normed tables. Scaled scores have a mean of 10 and a standard deviation of 3. These scaled scores are subsequently aggregated to derive the Composite Scores (Index Scores) and the FSIQ, which have a mean of 100 and a standard deviation of 15. The manual emphasizes the importance of calculating the General Ability Index (GAI) in cases where significant discrepancies between Working Memory or Processing Speed and the other indices might suppress the FSIQ, providing a more stable estimate of core intellectual potential. wisc-iv administration and scoring manual pdf
