While young female offenders remain a small minority within the juvenile justice system, the unique needs and program demands of this population require particular attention in terms of research and policy. This report provides survey instruments and basic research guidelines that can be used to collect empirical data on youthful female offenders and their program needs. Basic steps in collecting this information include a profile of the youthful female offender population; an on-site survey of existing facility-based programs; and a needs assessment that matches profile data with program data to determine gaps between the needs of girls and young women and current program availability. The report describes the steps necessary to conduct a needs assessment. The issues that differentiate the management of youthful female offenders include victimization, addiction, healthcare, pregnancy and parenting, reentry, housing, and job training and placement.
