WPPSI–IV / WIAT-III Combination Reports

Two options for scoring and reporting the WIAT-III are now available on Q-global.

The first option is to pay per-report. Customers who administer the WIAT-III only a few times each year, or those who want the flexibility to pay only as the assessment is used, may prefer this option.

The second option is to select an "unlimited use" subscription, where one user of the WIAT-III gets unlimited scoring and reporting for one, three, or five years depending on the selected term of the subscription. This may be a better option for customers who administer the WIAT-III several times each year—and don't want to worry about keeping track of their report expenses.

Scoring and/or Reporting Options

Q-global™ Web-based Administration, Scoring, and Reporting – Enables you to quickly assess and efficiently organize examinee information, generate scores, and produce accurate comprehensive reports all via the Web.

WIAT-III on Q-global also provides:

  • Enhanced skill analysis for core subtests at item level and sub-item level
  • Intervention goal statements for core subtests to assist with IEP goals and to help develop planning for intervention
  • Annual goals and short-term objectives for problem areas based on specific abilities, strengths, and weaknesses
  • Research-supported alternatives for determining severe learning disability and non-responders within an RTI environment
  • Parent Report, with a description of each subtest, as well as information to help the parent understand the WIAT-III scores

Q-global Unlimited-use Scoring Subscriptions

Two pricing options are now available for scoring and reporting on Q-global. In addition to the current per-report price, there is now an unlimited-use scoring and reporting subscription available in one-, three-, and five-year terms.

Important note: Each subscription is per user for the WIAT-III only and will begin on the date of order processing unless otherwise requested.

Pre-recorded Webinars

  • Application of Cognitive Hypothesis Testing Using PSW Analysis

    Presenter: Adam Scheller, Ph.D., Senior Educational Consultant with Pearson Clinical Assessment

    School districts across the country have adopted new and modified old(er) special education evaluation processes in line with the requirements outlined in IDEIA 2004. Since this revised legislation opened the door for schools to use several different means to qualify students with special education needs, we have witnessed an explosion of RTI programs and a subsequent decline in discrepancy-model usage. However, one area included in the law has received less fanfare, the process of analysing the concordance (and thus discordance) between related cognitive and academic processes. During this one-hour webinar Dr. Scheller will review this process of cognitive hypothesis testing by taking an in-depth look at how to apply widely used assessments such as the WISC-V, KTEA-3, and WIAT-III. Dr. Scheller’s goal in this one-hour webinar will be to help take clinicians to a level of detail and accuracy when forming and testing hypotheses about a child’s patterns of thinking and learning.
