This report reviewed results and recommendations of a project exploring youth recidivism, including to determining whether youth recidivism could be analysed using data from the Juvenile Justice National Minimum Data Set (JJ NMDS). There are substantial benefits in using a longitudinal data collection such as the JJ NMDS, but also some limitations. Preliminary data analysed showed that nationally, over two-fifths (43%) of young people with sentenced supervision in 2010-11 had returned to sentenced supervision within 1 year, while over three-fifths (63%) of those with sentenced supervision in 2009-10 had returned to sentenced supervision within 2 years.
