In this article, the authors trace the course of school discipline over the past 20 years and examine the status of school discipline reform today. They begin with an examination of zero-tolerance, suspension, and expulsion policies, as well as their assumptions and effects. They discuss alternatives that have been proposed and the guidance that has been offered by the federal government, and examine state changes that may be models for others. Finally, for any new model to be effective, support of teachers and administrators is essential; thus, the authors consider what educators really need if they are to successfully reform school discipline.
