Applied Behaviour Analysis employs methods based on scientific principals of behaviour to build socially useful repertoires and reduce problematic ones.
It focuses on teaching small measurable units of behaviour systematically.
Appropriate responses are followed by effective reinforcers often specific to each student.
Problematic responses such as tantrums, self injury and withdrawal are explicitly not reinforced which requires systematic analysis to determine the function of the behaviour for the individual student.
The key to success for the students involved lies in the use of small steps, over learning and generalisation of skills into natural settings.
