Four Hall County charter schools may not have their charters renewed due to confusion over state law governing control of charter school budgets. If the charters are not renewed, the schools are likely to become schools of choice. According to the Georgia Department of Education’s current interpretation of the law, decisions about personnel and budget at schools that renew their charters will have to be made at the school level by local governance councils rather than at the school system level, Hall County Schools Superintendent Will Schofield said Wednesday.
