Autism spectrum disorder (ASD) is a developmental disorder that impacts social interaction and communication. It is considered a spectrum because symptoms and severity vary widely between individuals. The defining features are difficulties with social communication and interaction, as well as restrictive and repetitive behaviors. ASD occurs in around 1 in 54 children and is diagnosed via evaluations of developmental history and observation of behaviors. Educational approaches for children with ASD focus on visual supports, structured routines, and encouragement of strengths and interests to help with learning and development.
