The ABC s of Response to Intervention & Behavior: Next Steps-A Practitioner s Guide to Implementation The ABC s of Response to Intervention (RTI) and Behavior is a practitioner s guide to implementing RTI and behavior based on research findings of other great researchers. This guide is user friendly and practical for real educators, those still in the trenches to use as a practical, easy to follow, step-by step guide to RTI implementation for students who exhibit challenging behaviors. The ABC s of RTI and Behavior is t intended to be a text book filled with excessive amounts of useless, meaningless research. This book was written by a teacher for teachers with the explicit intent to provide educators with a true resource for RTI and behavior implementation that makes sense, is based on research-findings, and is effective for both teacher and student success.
