A nonprofit organization that tracks Georgia spending and policies by state leaders is warning school districts to prepare to “face growing financial pressures.” As school districts prepare to develop their budgets for the coming 2017-18 fiscal year, the Georgia Budget & Policy Institute predicts that more than $500 million promised by Gov. Nathan Deal’s proposed $9.4 billion education budget to fund student programs will be eroded because the state plans to shift other funding responsibilities back to local schools.
