Children must meet various physical demands during the school day in order to be successful from both an educational and a social standpoint. They use important motor skills to move in the halls, sit quietly at a desk, and participate with peers on the playground. Physical therapists play an important role in facilitating the development of these motor skills in order to allow for optimal participation and socialization for each student. This chapter provides a description of the various roles played by the physical therapist within the school setting. The physical therapist may provide direct service to children receiving related services, indirect service to teachers and other staff by providing instruction or recommendations for children within the classroom setting, and consultation for staff and administration addressing issues that affect the student population as a whole.
