What is the primary goal of discrete trial training (DTT) in ABA therapy?

The primary goal of discrete trial training (DTT) in ABA therapy is indeed a structured approach to teaching that provides clear instructions. This method breaks down complex skills into smaller, more manageable components or "trials." Each trial consists of a clear instruction or question, a prompt if necessary, and the learner's response. This structured format allows for the consistent presentation of learning opportunities and facilitates immediate feedback from the instructor, which is crucial for effective learning.

In DTT, by maintaining a focus on precise and straightforward instructions, therapists can systematically teach new behaviors or skills and help the learner to achieve mastery through repetition and reinforcement. This is particularly beneficial in working with individuals on the autism spectrum or those with developmental delays, as it provides a consistent framework within which they can learn.

The other options do not align with the primary goal of DTT. While assessing cognitive abilities is important in understanding an individual's needs, it is not the main focus of DTT. Improving student attendance and enhancing physical endurance are unrelated to the educational methodology that DTT embodies. Therefore, option A is the most appropriate answer as it accurately reflects the essence of discrete trial training in ABA therapy.
