Training and Technical Assistance


Training and technical assistance (TTA) is the planning, development, and delivery of activities designed to achieve specific learning objectives, resolve problems, and foster the application of innovative approaches to juvenile delinquency and child victimization prevention.


The Office of Juvenile Justice and Delinquency Prevention (OJJDP) provides national leadership, coordination, and resources to those working to prevent and respond to juvenile delinquency and victimization. A major component of these efforts is the provision of TTA resources that address the needs of juvenile justice practitioners and support state and local efforts to build capacity and expand the use of evidence-based practices.

Training and Technical Assistance Network

A network of OJJDP-funded TTA providers is dedicated to providing targeted TTA to policymakers and practitioners.
