Autism Screening and Assessment Evaluations

Public schools are required by law to identify all children with disabilities, including those with autism spectrum disorder (AU) (IDEA, 2004). Early identification is key because early treatment leads to better outcomes (Dawson & Osterling, 1997; Eikeseth, Smith, Jahr, & Eldevik, 2007). Although it is often difficult to suggest to staff and parents that a child may have autism spectrum disorder, there is a significant risk associated with failing to recognize the disorder and provide intervention when it is present.
