Which method is repeated until the criterion is met?

Discrete Trial Teaching (DTT) is the method that is repeated until the criterion is met. This structured teaching approach breaks down skills into smaller, manageable parts and teaches each part individually through repeated trials. Each discrete trial consists of a clear instruction or prompt, a student response, and feedback or reinforcement, allowing practitioners to systematically assess whether the learner has mastered the skill or concept.

The repetition in DTT ensures that the learner has multiple opportunities to practice and demonstrate their understanding before moving on to the next skill. This method is particularly effective for teaching foundational skills and is widely used in Applied Behavior Analysis (ABA) settings, especially for individuals with autism.

Other options, such as Natural Environment Teaching (NET), Evidence-Based Practice, and Collaborative Learning, differ in their methodologies. NET focuses on teaching in natural contexts, Evidence-Based Practice emphasizes using the best research evidence combined with clinical expertise, and Collaborative Learning involves working together with others to enhance understanding. None of these approaches emphasize the continuous repetition of specific trials until criteria are met in the same structured manner as DTT.
