In recent decades, research and practice have shown that investing in a positive school-wide social culture is a key component of effective education. Evidence demonstrates that educators and students succeed when students are present, engaged, socially secure, and academically successful. Developed by 2M Research in conjunction with an expert panel and informed by a review of evidence using What Works Clearinghouse (WWC) evidence standards, these practice recommendations for educators draw upon studies of whole-school or whole-class interventions that support prosocial behavior in elementary school students, including students who are identified as having disabilities or who are at risk of identification for special education services. Moreover, these recommendations are based on research on promising interventions that show evidence of improved outcomes for student behavior, educator classroom management, and school environment. The panel offers elementary educators, administrators, qualified related service providers, and qualified school-based mental health practitioners the following five specific recommendations for prevention-focused practices that promote prosocial student behavior and related outcomes: (1) Implement School-Wide Procedures for Defining, Teaching, and Acknowledging a Small Set (e.g., 3-5) of Positive Behavioral Expectations; (2) Implement School-Wide Procedures to Ensure that Consequences for Problem Behavior (a) Prevent Escalation, (b) Interrupt and/or Redirect Problem Behavior to Expected Behavior, and (c) Minimize Inadvertently Rewarding Problem Behavior; (3) Use Coaching to Support Implementation of Evidence-Based Instructional and Classroom Management Strategies; (4) Collect, Summarize, and Use Fidelity and Student Outcome Data at All Levels for Iterative Decision-Making and Problem-Solving by Stakeholders; and (5) Implement the Organizational Systems Needed to Support the Initial Adoption and Sustained Use of Effective Practices with High Fidelity.
