Discrete Trial Training (DTT)

Discrete Trial Training is a specific learning opportunity which consists of a cue (referred to as a discriminative stimulus) accompanied by a prompt. The combination of cue and prompt evokes a response by the learner. Correct responses are followed by delivery of a preferred item. Incorrect responses result in a brief interval before the next trial is initiated. DTT allows for many teaching opportunities delivered at a fast pace, individualized selection of targets and increases in the child’s ability understand or discriminate the context under which the target response is appropriate.
