diagnosticTEACCH® Centers provide diagnostic evaluations for children, adolescents, and adults who are thought to have an autism spectrum disorder (ASD) but have not yet received a diagnosis. Evaluations typically consist of two visits to the clinic (varies depending upon the complexity of case and services provided) and focus on issues of diagnosis and educational programming and intervention.

The evaluation includes caregiver interview; review of medical, social, academic, and developmental history; caregiver questionnaires, and testing sessions with the individual. The individual is directly assessed using state of the art, empirically-based assessment instruments including the Autism Diagnostic Observation Schedule (ADOS) and The Childhood Autism Rating Scale – 2nd edition (CARS2). Results of the evaluation are shared with the parents during an interpretive conference that is typically held at the end of the diagnostic day. An individualized, written evaluation summary with comprehensive recommendations and resources is mailed to the family.

Due to the needed participation of the parent(s) and the comprehensive nature of a diagnostic evaluation, siblings or other young children, besides the client being evaluated, are not permitted to come to the evaluation. Please make your own arrangements for child care as our offices cannot provide child care and children cannot be left unattended in the waiting rooms.
