Schools are increasingly adopting tiered models of prevention to meet the needs of diverse populations of students. This article outlines the steps involved in designing and implementing a systematic Tier 2 behavior intervention within a tiered service delivery model. An elementary school example is provided to outline the identification, implementation, and data-based decision-making process. Recommendations are provided for teachers related to supporting the effective and systematic implementation of Tier 2 behavior supports. (Contains 1 note and 3 figures.)
