Recent legislative enactments have altered the boundary between US juvenile and criminal justice systems. Youth that were previously adjudicated as juveniles are increasingly being labeled "adults" and tried in the criminal court. This article begins with a review of policy and practice changes in the transfer of children to the criminal court. Through a discussion of relevant social and political discourses, the author examines the meanings of these changes for constructions of childhood and the contestation of childhood that they represent. The article concludes with a framework for analyzing and reconfiguring the trying of children as adults.
