Democrats have passed such a plan through both chambers, but Gov. Bruce Rauner, a Republican, says he'll veto parts of it.
Despite his veto threat, Rauner said Friday "We're going to make sure schools get open and we're gonna make sure that it's done on a basis that's fair for taxpayers all across the state, and it doesn't benefit only one community at the expense of residents of other communities".
Lawmakers approved a state budget this month that requires school funding be distributed through a new, more equitable formula that isn't law yet.
"If we wait any longer for Governor Rauner to do the right thing, principals will not be able to organize their schools, and we will use SB1's funding parameters to plan, since there are no other options on the table", Bittner said in a statement. "That's the only way this is going to get solved, and I think it's time that the governor take that approach".
Rauner will be in Rockford to discuss funding reform later on today.
On Monday, Rauner called on Senate President John Cullerton to send the legislation to his desk so he can issue an amendatory veto to remove certain funding considerations for cash-strapped CPS.
"Why are they sitting on that bill?"
However, a spokesman for Mayor Rahm Emanuel - who is traveling through Europe to boost Chicago's technology businesses - said the bill would benefit all schools in IL and "finally begin to close the state's worst-in-the-nation funding gap between wealthy districts and poor ones". It would ensure that none of the state's 850 school districts receives less than aid that the previous year, and would provide money to districts based on local property wealth and distinct student-population needs. His office posted a comparison chart online, but the numbers don't match official spreadsheets published by the state board of education. The bill establishes an evidence-based model that ties public school funding to "best practices" aimed at enhancing student achievement. Both Democrats and Republicans proposed a new evidence-based model, created to send more state dollars to districts with high poverty. Rauner accused Democratic legislative leaders of holding on to the bill to force a crisis.
