This resource provides a definition of RTI, reviews essential RTI components, and responds to frequently asked questions. This document lays out four essential components of RTI: a school-wide, multi-level instructional and behavioral system for preventing school failure; screening; progress monitoring; and data-based decision making for instruction, movement within the multi-level system, and disability identification (in accordance with state law). The information presented is intended to provide educators with guidance for RTI implementation that reflects research and evidence-based practices, and supports the implementation of a comprehensive RTI framework. The Essential Components of RTI - Placemat was developed as a supplemental resource to the Essential Components document.
