This bulletin is part of the best practice series on programs that provide assistance in building or expanding juvenile correction and detention facilities and in training correctional staff. These bulletins are designed to present up-to-date knowledge to juvenile justice policymakers, researchers, and practitioners about programs and approaches that hold juvenile offenders accountable for their behavior in an effort to help state and local governments develop programs in areas designated for JAIBG funding. Twelve program purpose areas were established for funding. This bulletin addresses five main themes to provide practitioners practical guidance and advice on best practices for construction, operations, and staff training for juvenile confinement facilities. They include: (1) construction decisions; (2) master planning; (3) facility development; (4) operations; and (5) training. It suggests that when searching for models and examples of best practice it is most productive to begin with people who are the best practitioners. (Contains 129 references.) (JDM)
