ABA DTT

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.
