Since RTI/MTSS became a major paradigm in school improvement efforts, nearly every book, article, or conference presentation has described it from a technical perspective. That is, they describe in intricate detail such items as how to conduct universal screening, how to do progress monitoring, how to establish cut-points for decision making, etc. However, only cursory, if any, attention has been given to school cultural factors at the school or district level. These factors are equally, if not more important, than the technical ones. This book addresses these and other school culture related topics that are central to the successful implementation of RTI/MTSS.
