This report describes how four law enforcement agencies, selected as learning sites, utilized the principles described in “Planning and Assessing a Law Enforcement Reentry Strategy”. “The goals of the learning site project were not to identify a gold standard or the most comprehensive law enforcement-driven reentry program in the nation, but rather to report how diverse agencies implemented strategies in key areas of reentry that many professionals on the front lines of this work face. Although the intended audience is primarily practitioners who have been charged with developing a reentry strategy for their agencies, it is also meant to have value for those individuals and agencies that partner with or hope to partner with law enforcement agencies to ensure that more individuals reenter communities safely and successfully” (p. 3). Three sections follow an executive summary: collaboration—coordination and partnerships; program terms—activities and scope; and data collection and analysis—process and outcome. Also included are profiles of the four law enforcement agencies evaluated.
