The Color Wheel System is a class-wide behavioral intervention that provides clear rules and expectations to decrease inappropriate behaviors. We implemented the Color Wheel in two classrooms that included students with autism to explore the effectiveness of the Color Wheel in inclusive classrooms within a Catholic elementary school setting. During implementation, there were large and immediate decreases in inappropriate vocalizations in both classrooms. The majority of the students liked the intervention, and the teachers saw positive changes in student behavior and wanted to use the Color Wheel with future classes.
