What is the WIAT-III?
The Wechsler Individual Achievement Test- Third Edition (WIAT-III) is a test commonly used by psychologists to determine a person’s academic strengths and weaknesses. The WIAT-III is made up of several subtests that measure a person’s oral language, reading, writing, and math skills.
The WIAT-III is made up of 16 subtests that make up four broader clusters including oral language, reading, written language, and math and takes about 60-90 minutes to administer. The WIAT-III can be used with individuals from preschool age through adulthood. The WIAT-III gives standard scores (similar to IQ scores), age equivalents, grade equivalents, and growth scores to help interpret performance.
What is the WIAT-III used for?
Results from the WIAT-III are helpful in determining where students should be placed in academic programs or if any accommodations would be helpful to them. Results from the WIAT-III can be extremely helpful in developing Individual Education Plans (IEPs) for students and in determining any learning difficulties or learning disabilities. The WIAT-III can also be helpful in determining whether children are eligible for any special services as defined by the Individuals with Disabilities Education Act (IDEA).
