HARRISBURG — A bipartisan panel of state lawmakers and advisers to Gov. Tom Wolf gave unanimous approval Thursday to a new formula to distribute aid to Pennsylvania’s 500 public school districts, a model that would funnel more money to districts with rising enrollment and students whose families are deeper in poverty.

The formula still does not have the agreement of the Legislature, and there are battles that remain to be fought over whether and when to start using the formula, and how much money to distribute through it. It also would not automatically correct the inequities built into Pennsylvania’s current system of distributing nearly $6 billion in for classrooms and administration.

For now, the formula endorsed by the 15-member Basic Education Funding Commission is being advanced as a way to inject transparency, fairness and predictability into distributing school aid in a state branded as harboring some of the nation’s worst disparities between wealthy and poor school districts.

The real-world effect of the proposed formula remained unclear, since the commission would not release a rundown showing exactly how money would flow through it to each district.

Wolf, a Democrat, said he supports the proposal.

It makes “really strong statement” that lawmakers from both parties could agree to it, Wolf said in an afternoon news conference.

Rep. Mike Vereb, R-Montgomery, a co-chairman of the commission, called the vote a “really historic moment” and pledged to seek rank-and-file support for it in the huge House Republican majority.

The unanimous vote came a year after then-Gov. Tom Corbett signed a law creating the commission to fix what many called a broken formula.

Education and school groups, including the Pennsylvania School Boards Association, Education Voters of Pennsylvania and Pennsylvania Partnerships for Children, quickly endorsed the commission’s product.

For the first time, the formula would recognize not just a district’s number of low-income students, but the number of students living at the deepest level of poverty and the proportion of the district’s enrollment they represent.

It also would emphasize a district’s current enrollment, addressing complaints from growing school districts and for the first time recognize a district’s charter school costs, geographic size and financial wherewithal to fund schools with local taxes.

The proposal arrives as Wolf is seeking the Republican-controlled Legislature’s approval for the state’s biggest-ever one-time increase in public school funding.
