Wechsler Individual Achievement Test (WIAT - III)

Educational | Abilities | Neuropsychology | Academic Functioning

A bit different from some of the other established Wechsler tests, the Wechsler Individual Achievement Test® – Third Edition (WIAT® – III) focuses on academic skills such as listening, speaking, reading, writing, and mathematics as opposed to measuring intelligence. Commonly used in educational settings as well as clinics, residential treatment, and medical facilities, the results from this comprehensive battery can be used by practitioners for a variety of purposes including identifying academic strengths and weaknesses, educational placement, learning disabilities, and gaps between academic achievement and a child’s level of intellectual functioning by comparing results from an intelligence test like the Wechsler Intelligence Scale for Children® -Fifth Edition (WISC®-VUK) with WIAT-III scores.
