Some schools have already been successful enough to have their charters renewed, which means their sponsors were satisfied that they met the original goals of their charter. A few charters have been revoked due to lack of proper financial management or lack of achievement. Charter schools have shown improvement in both parent and student satisfaction and in innovation in technology, curriculum, assessment, and governance. Through the Public Charter Schools Program the U.S. Department of Education offers grants to states, which then award subgrants to individual schools to assist them in planning, design, and initial implementation of new charter schools. Dissemination grants are also available to successful charter schools, with three or more years of experience, to support activities through which they help other groups open new or improve existing public schools.
Charter schools are also eligible for funding under other federal programs.
