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

If you leave the module prior to finishing, your place within the module will be saved. From your My Account page, look in the My Modules tab and select the last page viewed to resume this module.
