Even with the use of effective universal classroom management practices, some students will need additional behavioral supports. However, to translate implementation of new strategies into the classroom, professional development programs need to be adaptive to the complexities teachers face in providing instruction and managing classroom behaviors among diverse learners. Teachers also need support to successfully implement universal practices as well as to develop and enact plans for supporting students with disruptive behavior. This article describes a universal classroom management program that embeds coaching within the model. The coach supported teachers both in implementing universal strategies and in developing and implementing behavior support plans for students with disruptive behavior. The study evaluates the effectiveness of the behavior support plans and the types of coaching activities used to support these plans. Findings indicated that during meetings with teachers, coaches spent time action planning and providing performance feedback to teachers on their implementation of the behavior support plans. In addition, teachers reduced their rate of reprimands with the targeted at-risk students. Students receiving behavioral supports demonstrated decreased rates of disruptive behavior, increased prosocial behavior, and a trend toward improved on-task behavior. In comparison, a matched sample of students with disruptive behaviors did not demonstrate improved outcomes. Implications for practice are discussed.
