Discrete Trial Training and Autism Ranking:

Cost and Time

Cost

The costs of using DTT will depend to a large extent on who provides the training, how long it takes to implement the intervention, and whether support materials are purchased.

Time

Like many other interventions, the length and frequency of treatment will depend to a large extent on the needs of the individual.  For example, if DTT is delivered as part of a larger early intensive behavioural programme it may require many hours of work each day and be implemented over many years.

According to ICAN

"The total time for a DTI teaching sequence would be from 15 to 20 minutes in length. The student then would have a short break (5 to 15 minutes) between individual programs/lessons."

Within each DTI teaching sequence, each trial usually lasts between 5 and 30 seconds, with the teacher providing a break between trials.
