Discrete Trial Training (DTT) is an intensive treatment program used to help children with developmental disabilities such as Autism. DTT involves training a child with Autism a variety of skills that they may not pick up on their own. DTT programs usually start by training essential pre-learning skills such as sitting and looking at the teacher; social skills such as looking at other people, talking and interacting with others appropriately. Once the basic skills have been mastered, DTT works towards teaching higher-level skills.
