PHILADELPHIA - The Democratic candidates for Pennsylvania governor are poised to debate the problems and potential solutions in education.

The two-hour session is being held Wednesday night at the Free Library of Philadelphia.

The Philadelphia-based sponsors of the debate are the watchdog Committee of Seventy, the Philadelphia Education Fund and Congreso de Latinos Unidos, a Hispanic service group.

They say their goal is to have a thorough discussion about the fiscal and academic challenges facing public education in Pennsylvania so voters are informed and the candidates held accountable for their campaign promises.

All four candidates are scheduled to attend: state Treasurer Rob McCord, former state environmental protection secretary Katie McGinty, U.S. Rep. Allyson Schwartz and businessman Tom Wolf.

The debate is scheduled to be carried live by the Pennsylvania Cable Network.
