In this part of the video, Dr. Anne-Marie Kimball introduces the fourth edition of the Wexler Individual Achievement Test (WIAT-4), scheduled for release in fall 2020 by Pearson. The WIAT-4 is a comprehensive clinical tool designed to assess the achievement of individuals aged 4 to 50 years in various domains, including listening, speaking, reading, writing, and mathematics. It offers 20 subtests that can be administered in both paper and digital formats. Key features include in-depth coverage across achievement and language domains, making it suitable for educational, clinical, and research settings. The WIAT-4 supports multiple administration and scoring options, such as paper and hand scoring, digital administration via Pearson’s iPad-based system (Q-interactive), and a combination of both. The updated edition includes new norms, subtests, revised items, improved content coverage, enhanced user-friendliness, and clinical utility. It also offers additional scoring and analysis features through digital platforms, such as discrepancy analysis for learning disabilities and automated scoring of essay compositions. The content has been meticulously reviewed to ensure fairness and accuracy across diverse populations.

In this part of the video, the presentation focuses on the new subtests and composite scores of the Wyatt 4, highlighting key features such as the dyslexia index scores, automated scoring of the essay composition subtests, and simplified scoring of the sentence composition subtests. The Wyatt 4 includes 20 subtests, with significant updates from the Wyatt 3, including two new subtests for language processing—phonemic proficiency and orthographic choice. The segment details how phonemic proficiency involves orally manipulating sounds within words, while orthographic choice requires selecting the correctly spelled word from similar-sounding options, available only on Q-interactive. The Wyatt 4 also introduces three new fluency subtests: orthographic fluency, decoding fluency, and sentence writing fluency, each with specific timed tasks. Composite scores, derived from groups of subtests, provide a broader assessment of academic functioning, with the Wyatt 4 offering 14 composite scores, including core and supplemental composites.

In this part of the video, the detailed structure, functionality, and features of the Wyatt 4 assessment are highlighted. The Wyatt 4 is designed to evaluate the academic achievement of students from grades K through 12. It includes core composites that measure fundamental skills in reading, writing, and math, and provides a total achievement score.
Additionally, there are ten supplemental composites categorized into reading-related skills, academic fluency, language processing, and dyslexia screening. These composites offer a comprehensive understanding of a student’s learning profile by evaluating specific areas such as basic reading, phonemic proficiency, reading fluency, and various aspects of language processing.
The dyslexia screening composite consists of index scores tailored for different grade levels, aimed at identifying the risk for dyslexia. The video also explains the essay composition subtest scoring options. Examiners can choose between automated scoring systems via cue global or interactive platforms, or manual hand scoring, for reliable and efficient assessment results.

In this part of the video, the examiner describes the scoring process for essay composition in the Wyatt 4 assessment. They explain that essays are scored based on the number of correct versus incorrect word sequences. The raw score is derived from subtracting incorrect sequences from correct ones. Unlike the Wyatt 3, the Wyatt 4 emphasizes grammar, syntax, and mechanics, rather than cohesion, creativity, and audience awareness. It includes sub-tests for sentence building and sentence combining, assessing content, semantics, grammar, and mechanics, with sentences scored across multiple areas. Furthermore, the Wyatt 4 assessment is designed to assist in identifying specific learning disabilities as specified by the Individuals with Disabilities Education Improvement Act of 2004.

In this segment of the video, the discussion focuses on the Wechsler Individual Achievement Test, Fourth Edition (WIAT-4). It explains that the WIAT-4 provides various forms of error analysis and intervention strategies, useful in assessing and diagnosing dyslexia and other learning disorders, as recommended by the DSM-5 and the International Dyslexia Association. The segment highlights that the WIAT-4 includes error analysis worksheets for subtests like word reading, pseudo word decoding, math problem solving, and spelling, among others. Additionally, it explains how digital scoring systems offer error analysis and intervention goal statements. The WIAT-4 is also designed to track changes in scores over time to monitor progress and the effectiveness of interventions.
