GADS™

The GADS has been particularly noted for its ability to distinguish Asperger's Syndrome from Autistic Disorder. Suitable for individuals between the ages of 3 and 22, the GADS provides documentation about the essential behavior characteristics necessary for diagnosis and can be used to document behavioral progress, to target goals for Individualized Education Programs (IEP), and for research purposes.
