This document discusses Response to Intervention (RtI) and creating effective Tier 2 and 3 literacy interventions for adolescents. It provides validation for RtI approaches, outlines practical strategies and resources for implementation, and discusses information to further refine RtI programs. Key points include organizing interventions in tiers of increasing intensity based on student need, using data to drive decision making, and matching interventions to assessed student needs in domains like word study, fluency, vocabulary, and comprehension. Direct and explicit instruction is emphasized along with intensive small group work for struggling readers.
