This study evaluates the impact of the Maryland Reentry Partnership Initiative (REP) on crime in Baltimore between 2001 and 2005. It compares 229 REP clients to a contemporaneous cohort of 370 prisoners released to non-REP neighborhoods in Baltimore City. The quasi-experimental design tests whether REP reduced the prevalence and incidence of criminal justice contact, and whether the program was cost-beneficial. REP clients committed fewer new crimes, and that REP was cost-beneficial, returning $3 in benefits per dollar in new costs. The total net benefit to the citizens of Baltimore is $7.2 million, or $21,500 per REP participant.
