Now revised and expanded, this volume explains how to design, implement, and evaluate a comprehensive, integrated, three-tiered (Ci3T) model of prevention. Rather than presenting a packaged program, the book provides resources and strategies for designing and tailoring Ci3T to the needs and priorities of a particular school or district community. Ci3T is unique in integrating behavioral, academic, and social?emotional components into a single research-based framework. User-friendly features include tools for collecting and using student and schoolwide data; guidance for selecting effective interventions at each tier; detailed case examples; and tips for enhancing collaboration between general and special educators, other school personnel, and parents. In a convenient large-size format, the volume includes several reproducible forms that can be downloaded and printed for repeated use.
