This document provides a timeline for implementing Response to Intervention (RTI) in elementary schools. It outlines the three tiers of RTI: Tier 1 involves high-quality classroom instruction and screening; Tier 2 includes targeted small group interventions; and Tier 3 consists of individualized intensive interventions and a potential special education evaluation. The timeline also discusses identifying students for RTI using assessments, monitoring student progress, and ensuring ethical practices such as properly training teachers and involving parents.
