In this article, the authors clarify the role of the leadership team, providing a rationale for one integrated team to examine academic, social, and behavioral programming, with careful attention to including all key stakeholders. Next, the authors discuss the procedures for teaching all key stakeholders the comprehensive, integrated, three-tiered plan, followed by information on how to reinforce these groups for participation in the plan and meeting expectations. Then, the authors introduce core components needed to ensure accurate decision making with respect to primary prevention efforts: treatment integrity, social validity, accurate detection using systematic screening tools, and data-informed decisions. The authors conclude with a brief summary of how to implement and monitor Tier 1 efforts.
