WPPSI™ Test (Wechsler Preschool Primary Scale of Intelligence) Overview

What is the WPPSI?


The WPPSI (Wechsler Preschool and Primary Scale of Intelligence) uses subtests to determine a child’s Verbal and Performance IQ scores as well as the processing speed for children ages 2.5 years old to 7.25 years old. The WPPSI uses composite scores to assess a student’s general intellectual ability and cognitive functioning based on their test performance and current age. The test typically takes less than an hour and is given one-on-one by a trained psychologist.

The WPPSI-IV is often required by private schools and some gifted and talented programs or schools as part of the application screening and admissions process; it is administered by the Education Records Bureau (ERB). The WPPSI-IV can also be used to identify cognitive delays, learning disabilities and be combined with other tests to assess each child’s level of intellectual giftedness.
