The Classroom SCERTS Intervention Project (CSI) is an ongoing randomized clinical trial funded by the US Department of Education, Institute of Education Sciences. Drs. Wetherby and Morgan of the FSU Autism Institute are Co-Principal Investigators and are conducting this study in the public schools in Florida and California. CSI provides coaching and instruction to teachers serving students with ASD in both general and special education settings. We are currently conducting a randomized group research study of CSI over 4 years with 300 students with ASD in 80 Kindergarten through 2nd grade classrooms to test the effects of SCERTS implementation on social, communication, and adaptive behavior outcomes as compared to business the SCERTS curriculum compared to business-as-usual education curriculum. The findings of this study will provide important evidence of the effects of a comprehensive intervention conducted in public school settings for students with ASD.
