Whole-school or whole-class programs designed to promote positive behavior can enhance the likelihood that effective teaching and learning occur for all students. This practice guide is intended to help elementary education educators, as well as school and district administrators and parents, implement and support effective prevention-focused strategies that promote positive student behavior and related outcomes. In considering the growing body of research on prevention-focused frameworks to improve students' academic and behavior outcomes, this practice guide focuses on whole-school or whole-class practices to support positive behavior by elementary school students, including students identified as having disabilities or who are at risk of identification for special education services. This protocol guides the systematic review of research that informs recommendations for the guide, "Promoting Social and Behavioral Success for Learning in Elementary Schools: Practice Recommendations for Elementary School Educators, School and District Administrators, and Parents" (ED617775).
