Scientific Researched Based Intervention

SRBI comes from its emphasis on uniting scientific, research-based practices with systems approaches to education. Scientific evidence is substantial for a number of areas central to children's school success and well-being, such as reading, language development, and some areas of mathematics and social-emotional learning.

Tier I comprises core general education curriculums and instruction, attention to the quality of the school climate, as well as a comprehensive system of social-emotional learning and behavioral supports for all students.

Assuming that Tier I practices are effective for most students, instruction is culturally relevant, and there is appropriate differentiation of instruction, students who fail to make adequate progress in Tier I should receive Tier II interventions.

Tier III. Students continuing to make inadequate progress despite Tier II interventions are considered Tier Ill. The primary difference between Tier II and Tier Ill interventions involves the intervention's intensity and/or individualization.
