With this solicitation, BJA seeks to provide financial and technical assistance to states, state courts, local courts, units of local government, and federally recognized Indian tribal governments to plan, implement, and enhance the operations of VTCs including service coordination, participant service and supervision coordination, fidelity to the VTC model, and recovery support services. VTCs effectively integrate evidence-based substance use disorder (SUD) treatment, mental health disorder (MHD) treatment, treatment for co-occurring disorders, mandatory drug testing, incentives and sanctions, and transitional services in judicially supervised criminal court settings that have jurisdiction over veterans with treatment needs in order to reduce recidivism, increase access to treatment and recovery support, and prevent overdose.
