In a pitched battle over the state’s role in creating and funding charter schools, the voices are loud, passionate and coming from several sides. On an issue that will ultimately be determined by Georgia voters Tuesday, district superintendents, charter school leaders, columnists and elected officials — including several congressmen, State School Superintendent John Barge, and Gov. Nathan Deal — have all weighed in.The contention centers around a proposed amendment to the Georgia state constitution that would, if passed, guarantee the state power to approve and finance public charter schools.A “yes” vote would re-establish a state Charter Schools Commission that could overrule decisions by local school boards opposing new charters; it would also provide equitable funding to new and existing public charter schools, which, for the most part, receive fewer dollars per-student than schools in traditional districts.
