A $1.2 billion budget for Gwinnett County Public Schools gets final scrutiny Thursday night. The second and final public hearing on the budget is set for 6 p.m. at the school system's instructional support center, 437 Old Peachtree Road. It is scheduled for adoption during the school board's regular monthly meeting at 7 p.m. The budget, which is down $60.6 million from this year's spending plan requires two unpaid furlough days and larger class sizes. It also is being balanced by leaving open 585 jobs being vacated primarily through retirements and normal attrition.
