Product Details

WPPSI™-IV: Now Available

WPPSI™-III — Totally Restructured Based on User Input and Expert Panel Review to Build a Better Assessment from Start to Finish

The improvements we've made to the Wechsler Preschool and Primary Scale of Intelligence™-Third Edition (WPPSI™-III) are the result of research gathered from customers, expert advisory panels, professionals in the field, and children who have been involved in the testing process. Consequently, WPPSI™-III features shorter, more game-like activities that hold the attention of children as young as 2-1/2 years. Simplified instructions and scoring procedures enhance the ease of administration for examiners. Both children and examiners benefit from the thoughtful, carefully constructed revisions implemented to build a highly respected, reliable test that completely reflects what customers and other professionals told us they wanted for WPPSI™-III.

Now you can have a reliable and valid measure of intelligence in young children that is more age-appropriate and user-friendly. These significant improvements provide more clinically useful information for diagnosis and planning, making WPPSI™–III an even more powerful tool.

Features & Benefits

Improved Age Appropriateness

WPPSI™-III has undergone substantial revision to increase the scale's age appropriate properties.

  • Age range has been lowered to 2 years 6 months, allowing for earlier testing of children who could benefit from earlier intervention with special services
  • Scale has been divided into two age bands, 2:6-3:11 years and 4:0-7:3 years
  • Younger children take fewer subtests that are designed to measure verbal comprehension and perceptual organization abilities
  • Older children take a greater number of subtests designed to measure verbal comprehension, perceptual organization, and processing speed abilities
  • Less emphasis on acquired knowledge
  • Instructions to children have been simplified
  • Elimination of time bonuses due to the normal lags in motor skill development relative to cognitive skills
  • Use of queries and prompts is generally unrestricted
  • All stimulus booklet art has been redrawn to be more colorful and more closely resemble illustrations found in materials familiar to children

Increased User-Friendliness

WPPSI™-III test materials have been modified to make administration of the scale as user friendly as possible.

  • Instructions to the examiner and scoring procedures have been simplified
  • New stimulus booklet page layout provides greater comfort and efficiency throughout testing
  • Elimination of Object Assembly shield makes presentation of puzzle pieces less difficult and time-consuming
  • All subtests now feature teaching and practice items
  • Overall testing time for core subtests has been reduced, especially for children in the younger age group, with 25-35 minutes required for them and 40-50 minutes required for the older children

Improved Psychometric Properties

The scale's psychometric properties have significantly improved.

  • New items have been added to ensure that all existing subtests have adequate floors, ceilings, and difficulty-level gradients
  • All items have been reviewed for ethnic, gender, regional, and socio-economic bias
  • Seven new subtests were developed to enhance the scale's measurement capabilities of fluid reasoning, receptive and expressive vocabulary, and processing speed
  • Significantly improved reliability and validity
  • Norms include Subtest Scaled Score and Composite Scores (e.g. FSIQ, VIQ, PIQ, PSQ)

Validity Studies Enhance WPPSI™-III's Clinical Value

Data from the WPPSI™-III validity studies allow a better understanding of the relative performance of clinical and non-clinical groups, while giving the examiner a better way to describe a child's individual performance relative to his or her appropriate reference group.

  • Additional clinical studies using groups include mental retardation (mild and moderate severity), developmental delay, attention deficit/hyperactivity disorder, cognitively gifted, autistic, expressive language disorder, mixed receptive/ expressive language disorder, and at risk for developmental delay
  • Additional validity studies linked the WPPSI™-III to the Adaptive Behavior Assessment System™ (ABAS™), the Wechsler Individual Achievement Test®-Second Edition (WIAT®-II), and the Differential Ability Scales® (DAS®) are added to reflect the IDEA Part C legislation which recommends the use of multiple diagnostic criteria for identification of children for special services
  • All revisions were driven by an advisory panel of experts, extensive literature review, customer, and examiner feedback, and additional professional expert reviewers

Areas of Assessment
