The most common reason to use educational testing in an evaluation for Asperger’s Disorder is to determine if a learning disorder is present. Asperger’s Disorder children often have very scattered academic abilities that cause them to appear brilliant in some areas and surprisingly incapable in others. Without the type of information that educational testing provides, it can be quite difficult for your child’s teacher to set appropriate expectations for your child.
To determine if a learning disorder or weakness is present, the evaluator will administer a standardized IQ test; the most commonly used being the Wechsler tests, of which there are preschool, elementary/middle school, and high school/adult versions. These tests are not the same as paper-and-pencil IQ tests sold at bookstores and on the Internet; these are the gold standard for accurate IQ testing and occur face-to-face.
A learning disorder evaluation will also include an academic achievement test battery. These are also administered face-to-face, directly to the child by the psychologist. Commonly used tests include Woodcock Johnson III, Kaufman, and Peabody Individual Achievement Test. If your child’s IQ is significantly higher than his academic achievement, he may be considered to have a learning disorder.
