In October 1998, policymakers in Delaware decided that juvenile recidivism should be assessed in terms of felony re-arrests; as such, the main measure of recidivism employed here is felony re-arrest following release from a juvenile detention placement. Two other measures of juvenile recidivism are also employed to provide a fuller picture of the problem: all re-arrests by type of arrest for fiscal year (FY) 2003 and felony plus misdemeanor re-arrest patterns for FY 1994 through FY 2003. Juveniles were tracked for at least 12 months following release from 4,518 Level V placements, from 4,316 Level IV placements, and from 733 Level III placements. Data sources included arrest data downloaded from the Criminal Justice Information System (CJIS) in January 2005. Summary statistics indicate that the for the Level III cohort released during FY 2003, the recidivism rate at 12 months for felony arrest was 44 percent; 45 percent for the Level IV cohort; and 25 percent for the Level V cohort released during FY 2003. Total re-arrest patterns are analyzed and cautions are offered for comparing and interpreting statistical data. Displays, figures, tables, appendix
