Technical Information

 

The WPPSI–IV A&NZ is an innovative measure of cognitive development for preschoolers and young children that’s rooted in contemporary theory and research. This edition also 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. These extensive enhancements are targeted to benefit both children and examiners.

New Australian & New Zealand Norms

The WPPSI–IV A&NZ has been standardised on Australian and New Zealand children aged 2:6–7:7. The normative sample is representative of the Australian and NZ census for age, gender, parental education, geographic location, and indigenous status.

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 2 ½. These reliable and child-friendly measures were specifically designed to help detect emerging working memory difficulties for early intervention.

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.

Improved Developmental Appropriateness

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

New Processing Speed Subtests

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

Simplified Instructions

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

More Efficient Test Administration

Numerous updates make administration as efficient and user-friendly as possible.

  • Testing time is maintained or reduced while construct coverage is increased.
  • Clear and concise examiner instructions, including shortened discontinue criteria and simplified substitution, invalidation, and proration rules.
  • Stimulus book contents distributed to maximise portability
  • New and durable storage solutions for manipulatives, including puzzles.

Improved Clinical Utility

Updates increase the practical usefulness of the WPPSI–IV.

  • Age range extended upward to 7 years 7 months
  • Scoring approach expanded to include strengths and weaknesses analysis at the index level
  • Reduced expressive language requirements
  • Updated and new special group studies

Content Modification

We would like to bring to your attention content modification that is being implemented on the WPPSI-IV Australian and New Zealand. The modification pertains to pages 364 and 365 of the Administration and Scoring Manual, Table D.5 Base Rates of Normative Sample Obtaining Various Differences Between the GAI and Selected WPPSI–IV Composite Scores, by Overall Sample. Based on careful analysis we have concluded that all data reported in the table are correct. This modification does not affect norms, reliability, or validity. Some customers have found the column headings

in this table to be confusing, therefore we are making this change in an abundance of caution to improve clarity regarding proper use of the table. The modification is intended to ensure that the WPPSI-IV materials meet the high standards of quality that you expect from Pearson and that interpretation is as clear and simple for users as possible. This modification will be made on the next printing of the Administration and Scoring Manual.

Please select one of the following three options:

  1. Download replacement pages.  Table D.5 can be modified by printing and gluing these pages over the existing pages 364 and 365 of the Administration and Scoring Manual. Download replacement pages here >

  2. Manually modify pages. Table D.5 can be modified by switching around the “-” and “+” labels by hand directly onto pages 364 and 365 of the Australian and New Zealand Administration and Scoring Manual.  Manual Edits >

  3. Request a sticker. Table D.5 can be modified by requesting a sticker to place over the existing “-” and “+” labels. Please call or email client services for replacement stickers. Emails us at info@pearsonclinical.com.au

We encourage you to select one of the modification options provided above as soon as possible to ensure that you have the most user-friendly content at your disposal.
