This action research was driven by the researcher’s interest in Autism and Discrete Trial Training- specifically the efficacy of implementation and the generalization of skills learned into the classroom. The researcher is a preschool teacher in her 15th year of Early Childhood education. The 4-week intervention was conducted during specially designed instruction, but also how those skills taught have been displayed during large and small group time. Throughout the 4 weeks progress was monitored using the CBTU recording sheets and DTT steps. Findings revealed common generalization of skills when the student was presented with the cue outside of the trial time. The largest impact was teacher/ paraprofessional training and consistent cues.
