The Good Behavior Game (GBG) is an interdependent group-oriented contingency management system successfully used in school settings to promote positive student behaviors. As a classroom management intervention, there is a large body of evidence for it increasing desirable classroom behaviors and decreasing problem behaviors across a range of student populations. Recent studies have also demonstrated that a positive reinforcement-focused version of the GBG can be successfully implemented using a software application. The purpose of this article is to provide a brief overview of the GBG and its evidence base and describe the steps for implementing the GBG with a freely available software application for classroom management.
