Wechsler Preschool And Primary Scale Of Intelligence – III (WPPSI- III)

Wechsler Preschool And Primary Scale Of Intelligence - III (WPPSI- III)

The Wechsler preschool and primary scale of intelligence (WPPSI) is an intelligence test designed for children ages 2years 6 months to 7 years 3 months developed by David Wechsler in 1967. It provides subset and composite scores that represent intellectual functioning of verbal and performance cognitive domains, as well as providing a composite score that represents a child’s general intellectual ability.

Uses of WPPSI

As an assessment of general intellectual functioning
As part of an assessment to identify intellectual giftedness
To identify cognitive delay and learning difficulties.

The US standardization of the WPPSI-III included 1700 children aged 2 year 6month – 7 years 3 months.

The reliability coefficient for the WPPSI-III US composite scales ranges from .89 to .95.

The WPPSI-III has been formally linked with the WIAT-II (The Psychological Corporation 2001).

The relationship between the WPPSI-III and the WPPSI-R, WISC-III, BSID-II, DAS, WIAT-II, and CMS was also explored in order to evaluate the assessments reliability. A number of special group studies were also carried out during standardization in order to improve the clinical utility of the tool.
