“In the past decade, attention to the challenges associated with people exiting state and federal prisons has increased tremendously. This increased attention is for good reason, as the impact of prisoner reentry on the well-being of individuals, families, and communities is well documented. Yet for every person released from prison annually, approximately 12 people exit local jails … NIC [National Institute of Corrections] launched the Transition from Jail to Community (TJC) initiative in 2007 to address the specific reentry challenges associated with transition from jail … More comprehensive than a discrete program, the TJC model is directed at long-term systems change and emphasizes a collaborative, community-based orientation … This report describes the TJC initiative, discusses the implementation experiences in all six learning sites, and presents findings from the implementation and systems change evaluation” (p. 9). Sections of this report include: the TJC model and its development; technical assistance and evaluation approach; model implementation in the learning sites; implementation and systems change approaches and evaluation findings; and conclusion. Appendixes provide: TJC Implementation Roadmap; case flow graphics; Triage Matrix Tool; Core Performance Measures Tool; baseline measures; intervention inventory; and TJC Scale Key.
