The Wechsler Individual Achievement Test, Fourth Edition (WIAT-4) is a thorough assessment tool designed to measure academic achievement in people ages 4 to 50. It checks skills like listening, speaking, reading, writing, and math.
That makes the WIAT-4 a good tool for education, research, and clinical settings when a comprehensive look at someone’s academic skills is needed. The results can help with planning educational interventions, spotting learning disabilities, and measuring academic progress.
There’s also a Canadian version, the WIAT-4-CDN, which includes adaptations for Canada in its manuals and stimulus book.
This article will cover what the WIAT-4 is, what it measures, and how it’s used. We’ll also discuss its strengths and weaknesses, so you can decide if it’s the right assessment for your needs.
