    Product Details

    The WIAT–III Dyslexia Index scores help identify risk for dyslexia among students in grades kindergarten through 12, or individuals ages 5 through 50.

    Benefits

    The WIAT-III Dyslexia Index Scores may be used:

    • As an evidence-based dyslexia screener
    • To identify students who may benefit from a more comprehensive evaluation or assessment battery
    • For research

    Scores

    The WIAT–III Dyslexia Index scores were designed to provide theoretically sound, reliable, and clinically sensitive composite scores for identifying risk for dyslexia among students in grades kindergarten through 12, or individuals ages 5 through 50. In 15 minutes or less, practitioners can obtain a Dyslexia Index score to screen for dyslexia and identify individuals who may benefit from a comprehensive evaluation or a more intensive intervention approach.

    A single score such as the Dyslexia Index is not sufficient to diagnose dyslexia. Rather, a diagnosis of dyslexia is based on a convergence of evidence gathered from multiple sources. However, the Dyslexia Index results may contribute to a more in-depth evaluation using the WIAT–III.

    Two Dyslexia Index scores are provided for the WIAT–III: 

    • One for grades K–1, and 
    • Another for grades 2–12 and adults up to age 50 (indicated by 2–12+)

    These Dyslexia Index scores are obtained by administering two or three subtests, respectively, from the WIAT–III (Pearson, 2009a). With the exception of the Response Booklet pages for the Spelling subtest, the materials needed to administer and score the Dyslexia Index subtests are available as part of the WIAT–III. The specific testing materials needed for administration are listed below:

    Subtests

    The WIAT–III Dyslexia Index: Grades K–1 includes two subtests:

    • Early Reading Skills
    • Spelling

    This composite is available for students in kindergarten and grade 1.

    The WIAT–III Dyslexia Index: Grades 2–12+ includes three subtests:

    • Oral Reading Fluency
    • Spelling

    This composite is available for students in grades 2–12 as well as adults up to age 50. The composite structure for both Dyslexia Index scores is shown below:
