Chapter I considers legal aspects of using paraprofessionals with emphasis on the stance of the Nebraska Professional Practices Commission. A second chapter outlines the roles and duties of teachers and aides, offers sample job descriptions for teacher aides, and describes guidelines for effective team relationships. A final chapter discusses the special education paraprofessional program in terms of administration, training, supervision, and evaluation of personnel. It is concluded that paraprofessionals play an important role by providing an opportunity for differentiated staffing and thereby enabling more productive and efficient use of professionals.
