To support parents of non-verbal children with autism spectrum disorder (ASD) or intellectual disability (ID), this resource explains common forms of nonverbal communication in simplified language. The list focuses on behaviors that align with the shared deficits in communication and social interaction identified in prior artifacts, as defined by the Individuals with Disabilities Education Act (IDEA). These nonverbal cues—such as gestures, facial expressions, and body language—help parents understand their child’s needs, emotions, and intentions, especially for children aged 0-12 years who may not use spoken language. Each item is clear, practical, and tailored to empower parents, drawing from clinical guidelines and resources like the CDC, Autism Speaks, and the American Association on Intellectual and Developmental Disabilities (AAIDD).
