Discrete Trial Training (DTT)

Discrete trial training consists of an adult using adult-directed, massed trial instruction, reinforcers, and clear contingencies and repetition to teach a new skill or behavior.

What Will I Learn?

The AFIRM model guides the learner through four lessons to facilitate:

  • Learning basic knowledge about discrete trial training (DTT).
  • Applying DTT in activity based scenarios that promote real-world application.

The DTT module will take approximately 2 to 3 hours to complete. However, the module is broken into individual lessons to help guide your learning:

Lesson Time to Complete
A Case for DTT 10 minutes
Lesson 1: Basics of DTT 20 minutes
Lesson 2: Planning for DTT 20 minutes
Lesson 3: Using DTT 45 minutes
Lesson 4: Monitoring DTT 20 minutes
Applying DTT 10 minutes
