(WPXI) – Gov. Tom Wolf’s education secretary told lawmakers on Monday that he expects students to go back to school in the fall, and the Department of Education will provide guidance in the coming weeks to prepare teachers and staff to return to school buildings. Schools have been closed since March under Wolf’s orders to try to stop the spread of the coronavirus, keeping more than 1.7 million public school children home and exposing big differences in the ability of wealthier and poorer districts to educate children online. Education Secretary Pedro Rivera, testifying in a Senate committee hearing, acknowledged that schools will need additional aid to respond to various challenges posed by school closures and the need to contain the virus.
