ABA
Applied Behaviour Analysis (ABA) is an evidence-based method of teaching based on a scientific and structured application of learning theory to education. ABA is based on research into the principles of behaviour such as positive reinforcement, shaping and modelling. These principles have derived many tactics which have repeatedly been demonstrated to increase learning effectively.

Behaviour analysts work at an individual level in systematically applying these and other principles to decrease inappropriate behaviours and increase appropriate and functional ones, with the goal of maximising the individual’s access to reinforcement. ABA begins with a detailed investigation of the individual's current strengths and needs, these needs are then broken down into smaller steps and if necessary are taught separately by reinforcing all instances of the new target behaviour. These smaller steps are then built upon and expanded until the student learns the ultimate goal.

ABA and Autism
ABA has repeatedly been shown worldwide to be a successul intervention for children with autism (Lovaas & Smith, 1989; Schreibman, 1988; Schreibman, Charlop & Milstein, 1993; Smith 1993). At ABACAS all therapy programmes including Speech and Language Therapy (SLT) and Occupational Therapy (OT) are taught through ABA. This enables the student's progress to be data-based and individualised to move at the student's own pace.
