Local, State, and Federal correctional institutions are being significantly affected by the growing number of gang-involved offenders being committed to these institutions. The article discusses policy and procedural issues facing corrections administrators and examines Ohio's development of threat group management strategies. In addition, the article provides information concerning national trends in youth gangs, the behavior of youth gang members in juvenile correctional facilities, and California's approach to dealing with gang-involved youthful offenders. The Ohio and California programs have not yet been the subject of objective, empirical evaluation, but they appear to address many of the needs and risks of individual gang-involved offenders and have received positive initial assessments by both participants and observers.
