Research indicates that students with emotional and behavioral disorders (EBD) may engage in severe disruptions and off-task behaviors in the classroom setting that adversely impact the learning environment. This leads to many students identified as having EBD being placed in alternative education settings, such as restrictive schools or residential facilities. Due to placement in more restrictive environments and high rates of disciplinary actions, it is especially critical to decrease disruptive behaviors for students diagnosed with EBD. In addition, classroom teachers report disruptive behaviors and conduct problems as a major barrier to teaching their students. An ABC multiple baseline across classes design was used in an alternative school setting to evaluate the effects of explicit social skills training combined with a group contingency on class-wide levels of engagement and disruptive behavior. Participants were students in the first through sixth grade diagnosed with EBD. Through the class-wide intervention, social skills acquisition deficits were targeted through social skills instruction and social skills performance deficits were targeted through reinforcement programs. Results showed an increase in engagement and a decrease in disruptive behavior across all classrooms as a result of the intervention package.
