Charter School funding is a can of worms. When a child transfers to a charter school the State portion of the funding follows the child. Plus about 5K of the local funding. Which is odd, when I vote for a levy for the Parma Schools I am voting for a levy for the Parma Schools, not some unknown Charter School. Also, the public school district despite just loosing 8 or 10 grand when the child moved still has to bus the child from their home to the charter school.
As for the failure of public education, if your suggestion is that charter schools are the answer you are mistaken. They are considerably worse in almost every category. Don't confuse Charter Schools with Private Schools. Two very different animals.
