The Wechsler Preschool and Primary Scale of Intelligence—Revised (WPPSI-R) (Wechsler, 1989) is a widely used, well standardized, technically sound measure of children's intelligence (Kaufman, 1992). The WPPSI-R, like the WPPSI (Wechsler, 1967), reflects WecHsler's view that intelligence is a global entity that is multidimensional and multifaceted with each ability being equally important. Like other Wechsler scales, the WPPSIR has a substantial research and clinical foundation supporting its use to accurately measure the intellectual ability of young children.


The WPPSI-R is an individually administered clinical instrument for assessing the intelligence of children aged 3 years through 7 years, 3 months. It is organized much like the WPPSI, with one group of primarily perceptual-motor Performance subtests and a second group of Verbal subtests. There are a total of 12 subtests (see Table 5.1), of which 10 are required and two (Animal Pegs and Sentences) are optional.

The 12 subtests are divided into two scales labeled Verbal and Performance. This division has both logical and empirical support. The logical basis for this division rests on the apparent nature of the child's responses to the task: motor responses to the Performance subtests and spoken responses to the Verbal subtests. The empirical rationale for this division comes from the results of several factor analytic studies of both the WPPSI-R and WPPSI structure, consistently finding two subtest clusters within the scale (e.g., Hollenbeck & Kaufman, 1973; Sattler, 1992). The two clusters or factors invariably correspond to the Verbal and Performance scales. (A complete review of these studies is provided in the WPPSI-R manual.)

Each of the 12 WPPSI-R subtests produces raw scores that are converted to norm-referenced standard scores (M = 10, SD = 3). These scaled scores are then summed across the five required subtests within the Verbal scale and the five required subtests within the Performance scale to obtain sums of scaled scores. Each of the individual sum of scaled scores is transformed to an IQ (M= 100, SD= 15). These two sums of scaled scores—VIQ and PIQ—also are summed to produce a Full scaled score s is transformed to an IQ (M = 100, SD= 15). In addition to the raw-score-to-scaled-score . . .
