The roles and functions of a school psychologist are multifaceted. School psychologists are traditionally trained in areas of assessment, intervention, consultation, and program evaluation, though they often participate in prevention and crisis intervention efforts and program evaluation (Harvey & Struzziero, 2008). School psychologists work at district, building, and individual student levels to provide comprehensive and effective services to children and families. Despite a wide range of responsibilities, the school psychologist works in conjunction with other school professionals (e.g., general and special education teachers, speech-language pathologists, audiologists, social workers, principals) and parents to foster individual student success. This chapter presents the general roles and responsibilities of the school psychologist, as well as the school psychologist's role within an interdisciplinary team when making appropriate educational decisions.
