Definition
Discrete trial training is a structured ABA teaching method using repeated, discrete trials: a therapist presents a cue, the child responds, and the therapist provides a consequence (reinforcement or correction). It is highly structured and repetitive.
Why It Matters
DTT has been used to teach specific skills but has faced criticism from autistic advocates for its focus on compliance and its history of suppressing autistic behaviors. It is one type of ABA, not synonymous with ABA as a whole. In most programs, the supervising BCBA decides whether DTT is used and for which goals.
Common Misconception
DTT is not the only ABA approach. Many practitioners have moved toward naturalistic methods. The appropriateness of DTT depends heavily on the goals, teaching toileting is different from training away stimming.
