A 2 years and 10 months old child receiving an early intensive teaching program using the Comprehensive Application of Behavior Analysis to Schooling (CABAS[R]) was taught using evidence-based teaching strategies and curricula based on existing research in both the applied and basic sciences. Progress was measured using behavioral assessment tools and mastery of pre-set learning criteria. Independent measures in the form of psychological assessments were also administered annually over a three year period. This paper will provide an overview of the learning profile provided and the results achieved. (Contains 2 figures and 7 tables.)
