Colt was 3 years and 6 months and scored a 36 on the CARS indicating mild–moderate symptoms of autism. Colt
communicated in one to two word sentences but rarely spoke unprompted. Colt’s stereotypy included: (a) repeated
manipulation of only one small part of a toy (e.g., pressing the same button dozens of times consecutively while ignoring a
toy’s other features), (b) tapping the sides of toys to make a soft sound, and (c) waving toys in front of his face. Colt’s IEP
included goals related to toilet training, school routines, communication (e.g., requesting preferred items), simple social
interactions (e.g., greeting peers), and play.
