As the Hall County Board of Education heads toward budget season, discussions have already begun on possible cuts to help balance a shrinking budget.According to Superintendent Will Schofield, the system will have to seriously consider changes in the way it operates now.“We have to look at creating a more efficient model of schooling, but in the short term there’s not much that’s not on the table,” he said.Discussions have started on setting priorities for field trips, cutting out-of-state professional travel, slashing fleet vehicle use in half, using furlough days, streamlining athletic and extracurricular travel and possibly not filling vacant positions.“We’ve got a number of vacancies throughout the system right now and we can, in tough times, choose not to fill all or a percentage of vacancies,” said Schofield. “Of course, that translates into class sizes getting a little larger.” School officials are anticipating low state and local funding, which make up about 90 percent of their total budget.Four years ago, the system’s operating budget was about $217 million.
