The WIAT-4 Dyslexia Index helps identify risk for dyslexia among students from pre-kindergarten through grade 12, or individuals ages 4 through 50.
Uses & Applications
The WIAT-4 Dyslexia Index may be used:
The WIAT-4 Dyslexia Index was designed to provide theoretically sound, reliable, and clinically sensitive composite scores for identifying risk for dyslexia across much of the age span. In 10 to 20 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-4.
Two Dyslexia Index scores are provided for the WIAT-4:
These Dyslexia Index scores are obtained by administering two or three subtests, respectively, from the WIAT-4.
The WIAT-4 Dyslexia Index: Grades PK–3 includes two subtests:
This composite is available for students in Pre-kindergarten through Grade 3.
This composite is available for students in Grades 4–12 as well as adults up to Age 50.
