Filling a vital need, this is the first comprehensive guide to supporting K-12 teachers in effective implementation of classwide positive behavioral interventions and supports (CWPBIS). The book presents a roadmap for designing and delivering professional development based on behavioral principles. Procedures are outlined for providing data-driven CWPBIS training and coaching that is responsive to the needs of each teacher. User-friendly features include illustrative case studies, learning questions and exercises at the end of each chapter, and reproducible training tools. The large-size format and lay-flat binding facilitate photocopying; purchasers also get access to a Web page where they can download and print the reproducible materials. [Foreword by George Sugai.]
