Response to Intervention (RTI) is a multi-tiered framework for providing educational resources efficiently based on student need. It involves universal screening, progress monitoring, and increasingly intensive interventions. Students identified as at-risk through screening receive evidence-based classroom interventions and those not responding move to more intensive tiers involving small group and individualized instruction. Data-based decision making guides placement and instructional changes. The example school implements RTI through three tiers of instruction and intervention, with some students responding adequately to core instruction while others require more support.
