There are several different models of interventions for ASD. Many of the educational and communication approaches focus on replacing dysfunctional behaviours and developing specific skills. There are also other interventions such as biomedical or dietary treatments. The effectiveness of some approaches has been supported by scientific research. Other newer or alternative therapies may not have been scientifically evaluated but have been reported to have produced benefits for some individuals.
ABA uses a variety of assessment and intervention methods in order to change behaviour and teach skills.

It can be used in a broad range of situations by a variety of individuals.
Discrete Trial Teaching (DTT) is a teaching method that was pioneered by Lovaas in the 1960s and can be used in ABA programs. Children are presented with a brief instruction or question and given a “prompt” (a clue or the answer) to help them answer correctly and receive a reward. If they get the wrong answer, they are provided with the correct one. Data is collected and progress is evaluated on an ongoing basis.
