The purpose of this study was to examine the use of a classwide positive peer reporting intervention known as "tootling" in conjunction with a group contingency procedure to reduce the number of disruptive behaviors in a third-grade inclusive classroom. Nineteen elementary students including four students with disabilities (i.e., specific learning disabilities and/or attention deficit hyperactivity disorder) were taught how to report their classmates' positive behaviors using the "tootling" intervention. Results indicated that the use of the "tootling" intervention in combination with a group contingency procedure decreased students' disruptive classroom behaviors, establishing a functional relation. Limitations of the study, implications for using tootling as a classwide positive behavior support, and future research questions are discussed.
