The expanding needs of children today demand effective prevention and treatment programs. Some model programs that address these needs are described here. Schools are now being called upon to serve a population with a tremendous multiplicity of physical, social, emotional, and academic problems in an atmosphere of public dissatisfaction with education. If reforms are to be realized, school psychologists will need to shift time away from psychoeducational assessment toward the promotion of healthy development. More collaboration and an emphasis on consumer satisfaction will be required. Current thinking and best practices are explored here in 85 chapters.
