Juvenile Justice Services administers programs and services around three organizational and functional areas:

Institutional Services: The Sununu Youth Services Center and the Youth Detention Services Unit provide an architecturally secure placement for committed juveniles and for NH youth involved with the NH court system prior to their adjudication.

Probation and Parole: conducts investigations and provides supervision of delinquent minors and Children In Need of Services (CHINS), as well as providing supervision of committed delinquents released from the Sununu Youth Services Center on parole. JJS JPPOs are located in the 12 DHHS District Offices and 5 itinerant offices.

Community Programs: all community-based services, both residential and non-residential, are administered by this unit, through JJS institutional and field staff in cooperation with the NH court system. The services are then delivered by local organizations and providers. These services include home-based therapeutic services, substances abuse assessment and counseling, mental health services and an array of residential services, (foster homes, group homes, and intensive treatment facilities).
