Discrete Trial Training

Discrete Trial Training (DTT) is based on the understanding that practice helps a child master a skill. It is a structured therapy that uses a one-to-one teaching method and involves intensive learning of specific behaviors. This intensive learning of a specific behavior is called a “drill.” Drills help learning because they involve repetition. The child completes a task many times in the same manner (usually 5 or more). This repetition is especially important for children who may need a great deal of practice to master a skill. Repetition also helps to strengthen long-term memory. Children receive positive reinforcement (for example: high-fives, verbal praise, and tokens that can be exchanged for toys) for producing these behaviors.
