In Georgia _most_ school districts are at the county level. But in some cases a city has a school district independent of the surrounding county - often if not always this is the county seat. In the Atlanta area, at least, Atlanta, Decatur, and Marietta have separate schools from the surrounding counties. (In the case of Decatur, this fact explains a lot of the higher property values there compared to adjacent unincorporated areas of DeKalb County.)
