TYJ is committed to a developmental approach that advances and supports implementation of best practices at every decision point in the youth justice system. Policies and practices must reflect an understanding of adolescent development and the effects of interventions while integrating this approach among all stakeholders.
TYJ believes the youth justice system and its affiliated partners must be informed by the research and knowledge about adolescent brain science and the understanding of positive youth development. The 2013 National Research Council report recognized the following in support of this belief system:
- Adolescents are less able to regulate their own behavior in emotionally charged contexts.
- Adolescents are more sensitive to external influences such as the presence of peers and the immediacy of rewards.
- Adolescents are less able to make informed decisions that require consideration of the long term.
These adolescent “truths” provide the foundation for the adoption and implementation of developmentally informed practices, policies and procedures that have proven effective in achieving the primary responsibilities of the youth justice system, which include accountability, prevention of re-offending, and fairness and just treatment for all youth.

Mr. Tuell began his career in the Fairfax County, Virginia Juvenile and Domestic Relations District Court by working as a probation officer, intake and residential group care worker, and Administrator for twenty-two bed, residential facility for chronically delinquent boys, covering the period from 1979-1996.

All of which detail proven frameworks and the transformative process by which youth justice systems can consistently produce positive reforms to produce improved youth outcomes.
