What just happened?
• DTT can be effective for any student that needs more structure
• Researched-based specifically as an intervention for autism
• Easy to learn & use
• Consistency among environments & personnel is key
Hmmm………..
• Is this the BEST method of intervention for individuals with autism?
• How does ABA:DTT affect socialization and development of social skills?
• How can we use ABA:DTT with other interventions for autism?
