Research on implementation of a case management plan informed by valid risk assessment in justice services is important in contributing to evidence-based practice but has been neglected in youth justice. We examined the connections between risk assessment, treatment, and recidivism by focusing on the individual criminogenic needs domain level. Controlling for static risk, dynamic criminogenic needs significantly predicted reoffense. Meeting individual needs in treatment was associated with decreased offending. However, there is "slippage" in the system that reduces practitioners’ ability to effectively address needs. Even in domains where interventions are available, many youth are not receiving services matched to their needs. Implications and limitations of findings are discussed.
