Providing a unique on-the-ground perspective, this book examines the implementation of three empirically supported response-to-intervention (RTI) models in four different school districts. The book addresses the complexity of putting RTI into place in the elementary grades, showing how the process actually took place and what impact it had on school climates and student learning and behavior. The challenges of systems change are explored and key lessons identified for improving intervention outcomes. Invaluable reproducible tools developed and field tested during the implementation of each model can be downloaded and printed by purchasers in a convenient full-page size.
