Using the Juvenile Justice National Minimum Data Set to measure returns to sentenced youth justice supervision: stage 2

This is the second of 2 reports presenting measures of returns to sentenced youth justice supervision using data from the Juvenile Justice National Minimum Data Set (JJ NMDS). This report further examines timeframes for measuring returns and explores the potential for using JJ NMDS data to measure the seriousness of reoffending. A number of recommendations are made, including that timeframes of 6 months and 1 year be used; that an increase in sentence severity be used as an interim proxy indicator of escalating offending behaviour; and that future work include reporting on returns to sentenced supervision on an annual basis.
