The audience for these documents includes those interested in familiarizing themselves with the child welfare, alcohol and other drug services, and court systems. These documents are also intended for jurisdictions interested in or in the process of developing cross-systems relationships. The primer and guide are targeted to management and administrative personnel in State, county, and tribal jurisdictions' alcohol and drug services, child welfare, and court systems. The primer is not an exhaustive review of each system's mandates, practices, and policies. However, this document does provide an overview of the framework, target population, key legislation and funding sources, and structure and organization of services for each system.
