The document describes The P.L.A.Y. Project model, which is an evidence-based developmental intervention for families of young children with autism. The model is based on the DIR/Floortime approach and emphasizes parent training to support children's development through play. The P.L.A.Y. Project provides community workshops, professional training programs, and home consultation services to help parents facilitate their child's social, emotional and language development. Implementation of the model is compatible with occupational therapy and speech-language pathology in targeting the core deficits of autism.
