Test Results
The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) is a battery of tests that evaluates intellectual abilities.
The WISC-IV has 10 core subtests which make up four index scores, including the Verbal Comprehension Index (VCI), the Perceptual
Reasoning Index (PRI), the Working Memory Index (WMI), and the Processing Speed Index (PSI). The VCI is composed of subtests
measuring verbal abilities using reasoning and comprehension. The PRI is composed of subtests measuring perceptual reasoning,
spatial processing, and visual-motor integration. The WMI is composed of subtests measuring attention, concentration, and working
memory. Working memory requires the ability to temporarily retain information in memory, perform some operation or manipulation
with it, and produce a result. The PSI is composed of subtests measuring the speed of mental and eye/hand coordination. The PSI
provides a measure of the child’s ability to quickly and correctly scan, sequence, or discriminate simple visual information. Faster
processing of information may conserve working memory resources.
Intelligence tests like this one are samples of problem solving abilities and learned facts, and are good predictors of future
learning and academic success. However, there are several factors that the tests do not measure. For instance, they cannot
determine motivation, curiosity, creative talent, work habits, study skills, or achievement in academic subjects. These should be
considered when interpreting the scores in the report.
STUDENT obtained an IQ score of XX on the WISC-IV. Composite scores between the range of 90 and 109 are considered
average. However, given the extreme variability among Student’s Index scores, the General Ability Index (GAI) score provides a better
estimate of STUDENT’S true intellectual ability which is not negatively affected by his XXXX. This score is comprised of the Verbal and
Perceptual Reasoning subtest scores, without including the Working Memory and Processing Speed scores.
His/Her overall performance is classified in the Average range and is equal to or higher than that of % of children his/her age (*** th
percentile).
