What Is RtI?

RtI is an educational service delivery system designed to provide effective instruction for all students using a comprehensive and preventive problem solving approach. It employs a tiered method of instructional delivery, in which the core curriculum addresses and meets the needs of most students (Tier 1), additional instruction is provided for those needing supplementary intervention support (Tier 2), and intensive and individualized services are provided for the students who continue to demonstrate more intensive needs (Tier 3). At its foundation, RtI includes measuring performance of all students, and basing educational decisions regarding curriculum, instruction, and intervention intensity on student data.
