As dropout rates, drug addiction, and other problems continue to increase among youth, there arises a need for more effective approaches in dealing with problematic students. This book offers therapists and other helping professionals some practice-based solutions for fostering the healthy development of children and presents a model of therapeutic assessment and intervention that encourages effective collaboration among families, schools, students, and others within the school setting. The book is divided into four main parts. Part 1 explains key components, operational mechanics, and case studies of the school-based collaboration model. Part 2 outlines a philosophy and method of raising healthy children that is the foundation of successful, collaborative adult management of children. Part 3 reports case studies involving collaborative team interventions. Finally, part 4 presents guidelines for establishing and implementing a school-based ecosystem collaboration program. Contains over 100 references and an index. (GLR)
