A psychoeducational assessment to diagnose Autism Spectrum Disorder is a comprehensive evaluation of an individual's cognitive, academic, adaptive, and social, emotional, and behavioral functioning,  The assessment involves a battery of tests including measures of cognitive and academic achievement, as well as an evaluation of the individual's educational history and social, emotional, and executive functioning. Additionally, typically the Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) are utilized. The ADI-R and ADOS-2 are considered to be the gold standard instruments for Autism assessment and are required for a diagnosis in some provinces. The results of the assessment can be used to develop an individualized education plan and to guide decisions about accommodations and support services in educational and other settings. The assessment process begins with a parent intake meeting, typically three hours in length, followed by two testing sessions which are typically two to three hours each. Once testing is complete a detailed report will be written outlining the individual's strengths and areas of need, diagnostic information, and a detailed list of personalized recommendations for home and school. Results are shared with parents during a detailed feedback meeting.
