The Handbook of Research in School Consultation provides the field of school-based consultation with a comprehensive examination of research perspectives, methodologies, models of practice, and future research directions. The last decade has seen several critical developments in the study of school consultation, which provides structure and process for the adoption, implementation, and sustainability of systems and practices that support children’s learning and development. This preeminent collection brings together leading experts in the field to offer both producers and consumers of school consultation an invaluable snapshot of the current boundaries and rapidly growing content of the discipline. Thoroughly revised and expanded, the third edition broadens and deepens methodological and statistical foundations, details research on the science of consultee and organizational change, and specifies cultural, social, and linguistic aspects of school consultation research. New chapters on research design, teleconsultation, program and process evaluation, treatment integrity, social justice, transnational perspectives, and more will yield firmer competence and implementation of agreed-upon strategies. An ideal resource for researchers, trainers, and professionals in school psychology, school counseling, school social work, special education, and others, this handbook effectively keeps pace with the ever-evolving world of school consultation.
