Note: The forecasts are based on multiple randomized, longitudinal control trials of the active ingredients of this evidence-based practice. Benefits will vary as consequence of the quality of implementation, training, supports, commitment, and other variables; the predicted impact is greater for first-grade children with higher entering risks for internalizing and externalizing disorders. The cost savings and lifetime benefits increase if trained teachers use this evidence-based strategies in succeeding years for new entering cohorts of grade one children. While PAX GBG has well documented immediate benefits for students, teachers and schools in other grades, limited randomized longitudinal data exist to forecast similar benefits for other grades at this time.
