The Spring 2006 issue of the American Probation and Parole Association's Perspectives journal (Vol. 30, No. 2) features a collection of articles intended to extend the dialogue sparked by the Urban Institute's report, Does Parole Work? Analyzing the Impact of Postprison Supervision on Rearrest Outcomes. This article, posted with permission from the American Probation and Parole Association, begins with an argument for why we should study supervision, followed by an overview of the initial study. It concludes with some thoughts about policy opportunities for the field, arguing that the current focus on prisoner reentry provides a timely opportunity to "reinvent" parole.
