This document discusses Response to Intervention (RtI), a multi-tiered approach used to identify students who need academic or behavioral support. It utilizes universal screening, progress monitoring, and evidence-based interventions. There are three tiers - Tier 1 focuses on quality classroom instruction for all students. Tier 2 provides targeted interventions for students at risk of failure. Tier 3 involves intensive interventions, often including special education services, for students who need the most support. The goal is to meet the needs of all students through a highly integrated, data-driven system.
