The mission of comprehensive systems is to expand educational opportunities to the broadest potential audience in the most cost-effective manner. One entity is assigned responsibility for statewide planning, coordination and integration of programs. The state facilitates shared ownership and control of technology. Collaboration is mandated to maximize resources. Maine, Arizona, and British Columbia's Open Learning Agency are examples of comprehensive systems.
