Which Philly schools are still in-person?

The remainder of the district’s schools - about 150 traditional and alternative schools - will be open.

Why have schools decided to go virtual?

Philadelphia School District officials have said they want to keep schools open whenever possible, and want to avoid a blanket closure. In a letter to staff, Superintendent William R. Hite Jr. said the district will “continue to keep our schools open as consistently as possible as long as we have enough staff to maintain safe and orderly schools.”

District officials have said there’s no specific threshold a school needs to hit for closing, and that leaders examine each school’s staffing level, school climate, ability to attract substitute teachers, and other factors when deciding whether it can remain open or must shift temporarily to virtual instruction.

How many schools are in the Philadelphia School District?

There are 216 traditional public schools in the Philadelphia School District. (The city’s 85 city charter schools are authorized by the Philadelphia school board and funded by tax dollars but independently run.)
