The Wechsler Individual Achievement Test–Fourth Edition (WIAT-4: 2020) is an individually administered assessment of listening comprehension, oral expression, reading, writing, and mathematics. This webinar describes interpretation of data from the WIAT-4 reading and reading-related subtests. Participants learn to use WIAT-4 data to identify the nature of a student’s reading difficulties, and the interventions that are indicated based on the student’s scores.
