As response to intervention (RTI) is adopted by increasing numbers of schools and districts, knowledge about "what works" continues to grow. This much-needed book analyzes the key components of RTI service delivery and identifies the characteristics of successful implementation. Critically reviewing the available research, leading authorities describe best practices in multi-tier intervention, assessment, and data-based decision making. Clear-cut recommendations are provided for implementing evidence-based interventions to support students' needs in reading, writing, math, and behavior. A state-of-the-art resource for K-12 practitioners and administrators, the book also will fill a unique niche in graduate-level courses.
