For courses in General Methods and Response to Intervention. This book shows classroom teachers how to direct multi-tiered instruction by linking screening, monitoring and diagnostic achievement scores with evidence-based interventions in reading, writing, and mathematics.   Organized in two parts, it explores the multi-tiered instructional model found within the RTI framework and how to best implement it in the classroom setting. Beyond a theoretical perspective, it shows teachers which evidence-based interventions should be attempted based on specific achievement data and related progress scores. It includes reading, writing, and mathematics interventions that can be used for core Tier 1 instruction, supplemental Tier 2 supports and intensive Tier 3 interventions. Throughout the book, its emphasis is on using assessment data to make important instructional decisions that meet learner needs.
