Within a multi-tiered system of supports, resources are allocated in direct proportion to student needs. Data collected at each tier are used to measure the efficacy of the supports so that meaningful decisions can be made about which instruction and interventions should be maintained and layered. The multi-tiered system involves the systematic use of multi-source assessment data to most efficiently allocate resources in order to improve learning for all students, through integrated academic and behavioral supports.

To ensure efficient use of resources, schools begin with the identification of trends and patterns using school-wide and grade-level data. Students who need instructional intervention beyond what is provided universally for positive behavior or academic content areas are provided with targeted, supplemental interventions delivered individually or in small groups at increasing levels of intensity. This system is characterized by a continuum of integrated academic and behavior supports reflecting the need for students to have fluid access to instruction and supports of varying intensity levels.
