This paper presents the findings of a 4-year study that examined 225 cases of alleged sexual abuse of students by teachers. Data were collected through interviews with 225 superintendents who had dealt with incidences of sexual abuse--184 in New York State and 41 in other states. An analysis of 10 of these cases included interviews with superintendents, school attorneys, parents, and community members. The paper first defines sexual abuse and describes its different forms. The second section explains why administrators should pay attention to sexual abuse of students by staff. The third section compares the findings of various studies that have estimated the extent of sexual abuse by teachers and staff. Section 4 examines patterns of staff sexual abuse of students, and section 5 describes school district reporting patterns. Actions taken regarding the staff and students involved are discussed in sections 6 and 7. The eighth section offers suggestions for school-district prevention policies, and the ninth section presents guidelines for handling complaints and investigating charges. In summary, although the vast majority of teachers and staff do not abuse students, some do. The problem is exacerbated by lack of clear school policies, inadequate services for students who have been abused, and misinformation. Six tables are included. (LMI)
