@QuantMech , Michigan charter schools have no access to capital funding sources, such as bonds for buildings and technology. Despite that, according to a Stanford study, charter schools provide 2 additional months per year of learning.
The idea that charter schools are not accountable is ridiculous. They are accountable to the parents, who will send their children elsewhere if they are not satisfied. If you want to look at lack of accountability, look at your local public school system. Our district shuffles bad teachers and administrators between schools rather than firing them. That is one of the reasons we sent our kids to private schools.
@scout59 , Michigan has a on-line HS program too.
