For clinical, educational, or research teams who need a brief, performance-based dyslexia screener—including the new Phonemic Proficiency subtest—for ages 4 through 50, the WIAT-4 Dyslexia Index is an individually administered tool that provides risk assessment, strength of risk, and interpretive information for team and parent/caregiver communication. The WIAT-4 Dyslexia Index is the most current version.
