ATLANTA — Georgians must decide this fall whether the state can take over low-performing schools, a proposal backed by Republican Gov. Nathan Deal but fiercely opposed by education groups.For parents, teachers and others, the divide over Amendment 1 on November ballots is emotionally charged. Opponents warn that passage will leave parents with few routes to protest decisions made by an appointed official accountable to the governor.Proponents argue that those urging a 'no' vote are more concerned about adults working in schools than children assigned to school districts based on their addresses.The Nov. 8 vote is the latest attempt to institute a takeover model already used in Louisiana and Tennessee, with mixed results on student improvement.
