HARRISBURG, Pa. — Amid questions over mask-wearing requirements in schools, Gov. Tom Wolf’s administration is trying to make it clear that masks are to be worn practically at all times by students in Pennsylvania’s school, drawing complaints that school leaders must again change their preparations.

The administration this week released additional guidance that Health Secretary Dr. Rachel Levine said Tuesday clarifies the state’s intentions for mask-wearing in schools as they prepare to reopen in the coming days and weeks.

Masks must be worn in school, even when students and educators are six feet apart, Levine said.

But with some private or career technical schools already open, school officials say it is another frustrating change in guidance. They say they had previously been told that students and educators could remove their masks in the classrooms if they were at least six feet apart.
