"Through no fault of their own, millions of children have been exposed to and affected by the criminal justice system by witnessing their parent being arrested, by seeing their parent in court, or by visiting their parent in jail or prison. Indeed, many of the thousands of adult men and women who are arrested, prosecuted, and incarcerated each year leave behind minor children who must grapple with their parent’s absence for days, months, or years. Although such exposure does not always result in negative outcomes for children, the extant research does suggest that parental involvement in the criminal justice system can put children at risk of residential instability, economic strain and financial hardship, mental health problems, poor academic performance, and antisocial and delinquent behavior. Parental involvement in the system can be traumatic for children and can hinder the quality of the relationship they have with their parent ... This toolkit and the strategies and experiences described herein are intended for people who are interested in developing family-focused jail programs in their own jurisdictions, such as jail practitioners and community-based organizations working with jail administrators and jail detainees" (p. 1). Sections cover: family-focused jail programs; Children of Incarcerated Parents Bill of Rights; considerations for developing a comprehensive family-focused jail program-identify goals, ensure that the process is collaborative, determine what components should be in the program (parenting classes, coached phone calls, contact visits, and others), and implement the program (program structure and sequence, eligibility, and staff training); challenges and lessons learned (have adequate and appropriate space for the various program components, strike a balance between having fun and providing a service, minimize the trauma associated with visiting a parent in jail, account for high population turnover in jails, and secure adequate, sustainable funding); and conclusion.
