A current lawsuit alleges that Pennsylvania has broken its constitutional obligation to provide a "thorough and efficient system of public education." As part of a collaborative series for NPR, the new education reporter for Keystone Crossroads has been looking into education funding. WPSU's Emily Reddy talked with Kevin McCorry, who says there are huge funding disparities among Pennsylvania's 500 school districts and with Dan Urevick-Ackelsberg, an attorney at the Public Interest Law Center in Philadelphia, which is a part of the lawsuit.
