In July 1998, the Washington State Legislature eliminated parole for youth released from Juvenile Rehabilitation Administration (JRA) institutions for all but high risk and sex offenders. In a 2001 report, preliminary recidivism findings were compared for juvenile offenders released on parole with juvenile offenders released without parole. Results indicated that parole does not have an influence on recidivism. In this study, the Institute used a longer follow-up period and added a second comparison group. This 2006 study is therefore a more rigorous test of the effect of parole on recidivism for most juvenile offenders.
