Youth Justice
County governments play a critical role in shaping juvenile justice systems at the local level. As the primary providers of youth-serving services, county leaders are uniquely positioned to advance effective strategies that support youth when they encounter the justice system. By fostering collaboration among county agencies and bridging the gap between youth and community-based services, counties can create more coordinated and responsive systems. These efforts expand opportunities for diversion from formal court involvement, leading to better outcomes for youth, enhanced public safety and long-term cost savings.

Through technical assistance, national partnerships and member-driven initiatives, NACo’s Youth Justice programming equips county leaders with resources and peer learning opportunities to strengthen local youth justice systems. This initiative includes peer exchanges, best-practice reports and briefs that highlight effective county strategies for investing in and sustaining evidence-based approaches that foster positive outcomes for youth, families and communities.
How to Get Involved
The Counties for Juvenile Justice Innovation Network cohort was announced in Spring 2024 and concluded after nine months. NACo also hosted two peer exchanges in 2025.

Peer Learning
NACo’s Youth Justice program hosts peer-learning events that bring together county officials, youth justice leaders and experts to share best practices, address common challenges and explore innovative solutions. The events foster collaboration and build partnerships that improve outcomes for youth and strengthen families and communities.
In addition to these events, NACo develops county-focused resources that highlight actionable best practices in the youth justice system. These resources help counties turn ideas into action through case studies from counties across the country and are designed to be easily adaptable to local needs.
In June 2025, NACo hosted a Youth Justice Peer Exchange, which convened county officials to learn about key themes and emerging best practices in youth justice. The program focused on the following themes:
- Reliance on evidence-based strategies for early intervention
- Collaboration within intergovernmental systems and stakeholders
- Effective community engagement and partnerships
In September 2025, NACo hosted a Youth Justice Peer Exchange, with support provided by the Annie E. Casey Foundation. The program focused on the following themes:
- Collaboration with community partners to reduce out-of-home placements
- Innovative probation models grounded in adolescent brain research
- Adopting inclusive and person-centered language that emphasizes positive outcomes, reduces stigmas and mitigates negative connotations
