This practice guide will stress that efforts to safely reduce the inappropriate detention of low-risk girls must be rooted in JDAI’s [Juvenile Detention Alternatives Initiative’s eight] core strategies, but with an added intentional focus on applying those core strategies to girls’ unique needs and circumstances. These efforts require a strong and collaborative leadership team with the will and capacity to undertake meaningful reforms in the treatment of girls at the detention stage. The work must be rooted in careful analysis of detention management reports and individual case files to pinpoint policies or practices that may result in girls’ inappropriate or unnecessary detention, and they must lead to action as local leaders design, test and continually revise new strategies to meet girls’ needs (p. 2-3). Four chapters comprise this publication: understanding the challenge—the importance of focusing on girls in detention; getting started; using data to reduce inappropriate detention of girls; and developing a Girls Detention Reform Work Plan. Appendixes provide: Barnes County quantitative data analysis, Barnes County case file review, Girls Detention Facility Self-Assessment, and Making Detention Reform Work for Girls Research Question Worksheet.
