A tiered system of behavioral health and social-emotional supports is built upon a solid foundation of effective core instruction and practices that establish a safe and predictable learning environment for all students. This behavioral health and social-emotional framework should meet the needs of all learners, including those with diverse needs, as well as provide support for adults in the system.

Decisions across the tiers are made using a consistent data-based problem-solving process. Teams use data to determine the strength of the core/Tier 1 as well as when supplemental and/or individualized intensive intervention is needed for students.  Supports are continually evaluated for effectiveness and fidelity of implementation. Without effective and systematic processes to engage in data-based problem solving, schools and districts may be spending time implementing ineffective practices.
