The volume provides a comprehensive reference relating contemporary research and thought to quality professional services. Part 1, "Professional Issues," has sections on the profession and professional supervision and leadership. Topics include ethics, legal issues, governmental relationships, and maintaining professional effectiveness. Part 2, "Focus on Systems," is divided into sections on supporting system functioning, and system level interventions. Some broad-based educational interventions are also included. Part 3, "Focus on Individualized Services," contains 55 chapters, grouped under "[The] Problem Solving Approach,""Assessment Domains for Intervention Planning,""Student Interventions," and "Specific Populations." Topics include progress monitoring, designing interventions, and measuring intervention effectiveness, as well as specific interventions. Part 4 (appendices) provides ethical guidelines, standards, position statements, state certification and licensing standards, a listing of training programs, and lists of medications used to treat children and adolescents. Each chapter contains a list of citations and at least five suggested readings. (EMK)
