What is a Tiered Intervention System of Support?

A tiered intervention system of support includes a combination of high-quality, culturally- and linguistically-responsive instruction, assessment, and evidence-based intervention, and data-based decision making for both academics and behavior. Comprehensive implementation of a tiered intervention system of support will improve instructional quality, provide all students with the best opportunities to succeed in school, and assist with the identification of learning disabilities, behavior-related disabilities, and other disabilities.
