DJJ's Community-Based Intervention (CBI) program serves as a model for Delinquency Prevention and Post Detention Services. The program is voluntary and provides strength-based, family-driven case management services to youth. Case managers work with youth and their families to: develop their own service plans, set goals for themselves, and model ways by which to accomplish goals. Based on clients’ identified needs, referrals are made to human and social services. In addition, CBI offers educational workshops, community service projects, school attendance monitoring, education advocacy, and cultural and recreational outings. CBI served almost 1100 youth in Fiscal 2001.

Youth are eligible for prevention services if they reside in one of the precincts or service areas served by the program.The program, which works with at risk youth, began in 1993 as the Reduce Children's Violence program. It began with two sites and has since expanded to 16 locations citywide.

Youth are eligible for post detention services if they were released home from a DJJ secure or non-secure facility. DJJ began providing post detention services in 1983; the program was formerly known as Aftercare. It won an award from the American Correctional Association in 1998.
