Wechsler Preschool and Primary Scale of Intelligence®—Fourth Edition: Canadian

The WPPSI–IVCDN is an innovative measure of cognitive development for preschoolers and young children that is rooted in contemporary theory and research. It places a strong emphasis on child-friendly, developmentally appropriate features and includes new processing speed tasks, the addition of working memory subtests, and an expanded factor structure. The extensive enhancements are targeted to benefit both children and examiners.

10 complimentary administrations

Content & Administration

Based on the most current literature in the field and feedback from experts and clinicians, the WPPSI–IVCDN includes extensive content changes including new processing speed measures, the addition of working memory subtests, and an expanded factor structure that includes new and separate visual spatial and fluid reasoning composites for ages 4:0 – 7:7.

New Working Memory Subtests

Picture Memory and Zoo Locations—the two new working memory subtests—provide age-appropriate, engaging tasks for children as young as 2½ years. These reliable and child-friendly measures were specifically designed to help detect emerging working memory difficulties for early intervention.

Test framework for each age band

Expanded and Updated Factor Structure

For both age bands the test structure includes three levels of interpretation: Full scale, Primary Index scale, and Ancillary Index scale levels.

The Primary Index scales include:

  • Verbal Comprehension Index (VCI)
  • Visual Spatial Index (VSI)
  • Working Memory Index (WMI)
  • Fluid Reasoning Index (FRI)
  • Processing Speed Index (PSI)

The Ancillary Index scales include:

  • Vocabulary Acquisition Index (VAI)
  • Nonverbal Index (NVI)
  • General Ability Index (GAI)
  • Cognitive Proficiency Index (CPI)

Features & Benefits

Improved Developmental Appropriateness

With consideration of the unique challenges of assessing young children, the WPPSI–IVCDN was redesigned to strengthen the emphasis on ensuring that all aspects of the WPPSI–IVCDN are developmentally appropriate.

New Processing Speed Subtests

Three new game-like subtests offer engaging art and use an ink dauber to indicate responses, thereby minimizing fine motor demands. Each subtest is built with careful consideration to the cognitive, motor, and language development of young children.

  • Bug Search and Animal Coding are adaptations of the WPPSI–IIICDN Symbol Search and Coding subtests
  • Cancellation is a more developmentally appropriate adaptation of the WISC®–IVCDN subtest version

Simplified Instructions

  • Simplified and shortened directions for children
  • Demonstration, sample, and teaching items used whenever possible to ensure clarity of task demands
