ERB/WPPSI™-IV
Ages 3-7


The WPPSI™-IV is an individually administered intelligence test that assesses a child’s current cognitive abilities in both verbal and nonverbal areas for children between the ages of 2 years 6 months to 7 years and 7 months. This is a change from the WPPSI™-III, which was administered to children 2 years 6 months to 7 years and 3 months. Younger children take fewer subtests than older children.

The WPPSI™-IV consists of 15 subtests. These subtests are designated as one of three types: core, supplemental, or optional. The core subtests are required to determine a child’s Verbal IQ, Performance IQ, and Full Scale IQ. The supplemental subtests give further information about a child’s cognitive abilities or can be used as replacement for other subtests. The optional subtests provide further information about a child’s cognitive functioning, but cannot be used as replacements for core subtests.

It is important to remember that the WPPSI™-IV is used as a psychological evaluation for children as well as an entrance exam into some private schools. Therefore, all of the changes to the exam will not necessarily influence those taking the test for school entry. For example, the ERB test used for private school admissions in New York City is a non-standard version of the WPPSI™, which includes and excludes several subtests of the WPPSI™ to measure more innate intelligence and skews the test towards measuring learned knowledge.

Beginning in April 2013, the ERB will make some big changes to the WPPSI-IV™ used for admissions into many private Pre-K, Kindergarten and 1st grade programs. The ERB added Bug Search to the Performance section of the test and Information to the Verbal section. The new WPPSI-IV has 8 subtests in total:

Verbal Subtests:

  • Comprehension
  • Vocabulary
  • Information
  • Similarities

Performance Subtests:

  • Block Design
  • Bug Search
  • Matrix Reasoning
  • Picture Concepts
