Foundations of School Psychology Research and Practice Series Editor: Craig Albers Competent school psychologists function simultaneously as scientists, scholars, and practitioners. Therefore, they need a foundation of evidence-based prac- tices to inform their services to educators, parents, students, and others. The Foundations of School Psychology Research and Practice Series offers school psy- chologists the context and skills they need to be effective in both research and practice, integrating in-depth and up-to-date coverage of important theories, methodologies, applications, approaches, and issues across a variety of topics. These books are intended for trainers seeking comprehensive course readings, researchers looking to examine concepts from school psychology-specific perspectives, and practitioners ready to build on and apply their knowledge and preparation.
