Applied Behaviour Analysis (ABA) is a science in which strategies from the principles of behaviour are applied to improve learning and behaviour.  ABA helps us understand how behaviour works and through these understandings, we can apply strategies in everyday situations.  ABA improves language, attention, social skills and academics.  Its procedures can also reduce problem behaviours.

Since the 1960s, therapists have used ABA to help individuals with special needs.  As an approach which is evidence-based, ABA is endorsed by US Federal & State agencies, the U.S. Surgeon General and the American Psychological Association.  “Evidence-based” means that ABA has passed repeated scientific tests of its effectiveness, quality and usefulness. Years of research attest that ABA help learners increase language and communication skills (e.g. Lovaas, 1987; NAC, 2009; Sallows & Graupner, 2005).  Many studies have established that intensive and long-term ABA therapy improves intellectual functioning, language development, daily living skills and social functioning in children with autism.  Studies with adults show similar benefits.

Based on the promising results of these studies, ABA is widely used and insured in the USA and Canada.  Multiple provincial governments of Canada (e.g. Ontario¹ and British Columbia) funds ABA services as a main eligible service for children and youths with autism.
