The School/Services for Autistically Impaired Learners, SAIL, is a researched-based program serving families with toddlers, preschool and early elementary school age children medically diagnosed with autism, pervasive developmental disorders (PDD), or behaviors within the autistic spectrum disorders (ASD). The goal of SAIL is to provide individualized, one to one, developmental instruction suggested by the National Academy of Sciences, National Research Council, to toddlers and preschool children with ASD. SAIL enhances maximum growth in cognitive, sensory, social, emotional, physical, functional language-communication, and aesthetic domains.
