CJJ members work to build safe communities one child at a time. With this vision in mind, CJJ serves as a premier national resource on delinquency prevention and juvenile justice issues. CJJ is based in Washington, DC, yet reaches every U.S. state and territory. Nationwide, more than 1,500 CJJ volunteers from the public and private sectors- professionals, concerned citizens, and advocates for children and families, and youth themselves- participate as members of state advisory groups on juvenile justice.
