People choose to create them because they perceive a need or opportunity. Nobody is forced to start one, work in one, or attend one. Although they are public entities, they are not government-run institutions. Control is vested in parents and citizens, often including poor and previously disempowered people. Folks who once thought themselves victims of the system suddenly become owners of their school.
Charter schools are communities for educators as well.
Since they confront less red tape, teachers can deploy their own judgment, set their own instructional priorities, pick their materials, and engage students in projects and activities that inspire them. All of this has the effect of creating a professional community in which staff feel a sense of collective responsibility for the school. In short, charter schools are learning communities in their own right but also become expressions of larger communities. Charter Schools' Impact on the System Most of the research on this point has been on the effects of charter-induced competition on the regular public school system. In most parts of the country the threat posed by charter competition is still very small and on the margin.
