Most questions now are about learning-effects.
Kids don't learn from charters, just as they don't learn from buildings. First is the idea of the state opening up a non-district sector within public education. The states with the 'complete' charter laws that generate live programs charter some public body other than the local board to create these new schools in the community. Kids may choose to attend, taking the money with them. Second is the idea of the board of education as the buyer of learning-services.
