Little League has three structural components, each dependent upon the other and each vital to the success of the program.
The administrative and service core of the movement is Little League Baseball, Incorporated, a non-profit membership organization that maintains the international program, with Little League International in Williamsport, Pennsylvania. Part of the Little League International structure includes various Regional Centers in the U.S. and throughout the world.
The next component is the District. All the leagues within a District (a geographical area usually encompassing 10-20 leagues) elect a District Administrator (DA). The DA and his/her staff of Assistant District Administrators serve as liaisons between the various Regional Headquarters and the local Little Leagues. They are usually the most experienced Little League volunteers in the area and are charged with helping to ensure that all the volunteers in their districts are well trained, and all the leagues are operating within the guidelines set by Little League. The District Administrator does not have the authority to suspend, limit or revoke any rules, regulations or privileges of charter by a local Little League, but may recommend such action to the Charter Committee in Williamsport.
The final, most important component is the local Little League. The league provides its services in the community. It furnishes physical facilities, volunteer services and resources to provide a program for children. Through effective leadership and strong administrative policy at the top level, together with training extensions and adherence to rule and policy at District and local league level, Little League is able to provide liberal benefits to children who participate.
