Juvenile Waivers to Adult Court: A Review of Outcomes for Youth, March 2011

This study followed four cohorts of youth in an effort to determine the impact of waiving youth from the juvenile courts to the adult justice system. The four cohorts included a group of youth who were automatically processed in the adult system due to the severity of the charges against them, a group waived to the adult system after starting in the juvenile court, a group returned to the juvenile court after having initially been waived to the adult system, and a group of “youthful offenders” who started supervision in the juvenile court with the option of moving into the adult system upon reaching age 18.

The Sex Offender Research Council’s Annual Report: An Analysis of the Sex Offender Special Sentence in Iowa, November 2014

To study the effects of the special sentence, two groups of sex offenders were analyzed: those serving a special sentence and a pre-special sentence cohort of offenders. Recidivism rates were compared between the two groups over a three-year period. For the special sentence group, the recidivism tracking period began at the beginning of an offender’s special sentence supervision start date. For the comparison group, the recidivism tracking period was observed following an offender’s sentence expiration, meaning that they were not under any type of correctional supervision when examined.
