PAX Good Behavior Game (PAX GBG) is a school-based, classroom intervention used by teachers to teach self-regulation. PAX GBG is not a set of lessons or curriculum, but strategies teachers use throughout their day to build students’ behavioral skills and stamina for focused attention and self-regulation. This is what makes PAX GBG so much more than good classroom management. Classroom management ends at the classroom door, but students take self-regulation with them in the hallways, to recess, into their homes and communities, and into their lives. Longitudinal research by Johns Hopkins University, has shown that students who received PAX Good Behavior Game are more likely to experience success in school and significantly less likely to experience difficulty with substance abuse or addiction.
