In 2007, the National Institute of Corrections partnered with the Urban Institute to develop and test the Transition from Jail to Community (TJC) model for effective jail-to-community transition. The TJC model and initiative advance systems change and local reentry through collaborative, coordinated jail-community partnerships. This brief details the two-stage screening and assessment process to determine risk and need levels in the jail population. It describes the importance of screening and assessment in an evidence-based jail transition strategy, including selecting screening and assessment instruments, implementing a screening and assessment process, and integrating risk and need information into comprehensive jail intervention strategies.
