The document provides an overview of Response to Intervention (RTI), which is a multistep process used by schools to provide early support for struggling students and improve identification of students who need special education services. It describes the typical three-tier RTI model where students receive increasingly intensive interventions based on their response to instruction. Tier 1 involves universal screening of all students and group interventions. Tier 2 provides more targeted small group interventions. Tier 3 involves the most intensive individualized interventions and possible evaluation for special education. The goal of RTI is to prevent academic failure and ensure all students succeed.
