Last week petitioners in Pennsylvania's school funding lawsuit filed a brief and affidavits refuting the claim made by the Republican leader of the PA Senate, Joe Scarnati, that the lawsuit was rendered moot because the state adopted a school funding formula in 2016.

The brief details how state funding increases have not kept pace with rising mandated costs, including pension expenses. Because of this, aggregate state funding available to school districts for classroom costs have effectively decreased by $155.3 million since 2013.

In addition, according to an affidavit filed by KRC Labor Economist Mark Price, funding gaps between low- and high-wealth districts have significantly increased since the case was filed. Four years ago, a typical high-wealth school district spent $3,058 more per student than a typical low-wealth school district. Today that difference has grown to $3,778/student.

In other words, four years ago, high-wealth districts spent $76,450 more for each classroom of 25 students than low-wealth districts. Today, they spend $94,450 more.
