Let's look at Georgia's non-unionized public schools. So far as I know, Georgia does not have teachers' unions. But there's still no reason to believe charter schools in Georgia would be any more magic than in Chicago.
According to CREDO at Stanford University, which has done state-by-state charter school studies, they find CHARTER SCHOOLS IN GEORGIA PERFORM SIGNIFICANTLY BELOW THEIR TRADITIONAL PUBLIC SCHOOL PEERS IN MATH: No Difference Found in Reading Performance. That's their press release. Here's the detailed study.
So if someone has a charter school idea that they think will perform better than public schools, they can talk to their local school board about that, and maybe that local board will agree. There's no need to authorize an unelected Atlanta board to force that charter school on us.
Vote No on the charter school amendment in November.
