Since the 1980's, fear of school violence has driven American public education toward increasingly punitive and exclusionary methods of school discipline. Yet recent research has begun to raise serious questions about the effectiveness and equity of suspension and expulsion. Despite such controversy concerning the use and effectiveness of suspension and expulsion, little is known about the actual perspectives of school principals; that is, to what extent do instructional leaders support the philosophy of zero tolerance in general, or the use of suspension and expulsion in particular? Previous research has suggested that there are distinctly different perspectives among principals towards school discipline and that these attitudes may be associated with differences in the use of suspension and expulsion. To address such questions, the authors surveyed Indiana's principals on their perspectives concerning school discipline and violence prevention strategies. Their goals were to (1) gain a sense of attitudes of principals towards school discipline; and (2) explore the extent to which principal attitudes and perspectives are related to disciplinary outcomes in Indiana's schools.
