Discrete Trial Training

"Discrete Trial Training is one of the most important instructional methods for children with autism"

- Smith (2001, p.86)

What is Discrete Trial Training?

Discrete Trial Training (DTT) is a method of teaching in simplified and structured steps. Instead of teaching an entire skill in one go, the skill is broken down and “built-up” using discrete trials that teach each step one at a time (Smith, 2001).

Sometimes you might see the term “discrete trial procedure,” “discrete trial teaching,” or “discrete trial instruction,” but these terms are all the same as discrete trial training.

Generally speaking, it is the most common used technique in ABA therapy while in the office.
