Autistic children drown at one-hundred sixty times the rate of their neurotypical peers: a public health crisis that the adapted learning field has only addressed by demonstrating that standard swimming instruction sometimes works for autistic children. This study presents a three-profile framework (sensory-seeking/hyposensitive, sensory-avoidant/hypersensitive, variable/mixed) founded in sensory processing literature, based on \~950 lessons to 65 autistic children (ages 3-15) to determine why this disjunction exists, and how swim instructors can fix it.
