Which instrument is a broad achievement test commonly used in schools and is abbreviated WIAT?

• A. Wechsler Individual Achievement Test
• B. Wechsler Intelligence Scale for Children
• C. Woodcock Johnson Tests of Achievement
• D. Wide Range Achievement Test

Answer: (A)

WIAT stands for Wechsler Individual Achievement Test, a broad achievement battery used in schools to assess academic skills across key domains such as reading, written language, mathematics, and often oral language. It’s designed to identify strengths and weaknesses in a student’s school-related abilities and to inform decisions about instruction, interventions, and eligibility for services. While other tests like the Wechsler scales focus on cognitive ability or other achievement batteries exist (such as the Woodcock Johnson Tests of Achievement or the Wide Range Achievement Test), WIAT is specifically the abbreviation for the Wechsler instrument. This makes WIAT the go-to choice when the question asks for the broad achievement test abbreviated WIAT.
