But they did send their teachers to a "trans welfare" training session

oh, and cloth masks are useless, whether or not they cover the nose

Philadelphia schools choose to ignore the CDC and will require children and staff to wear face masks when they return to school. It’s no doubt simply a coincidence, but the few school systems still forcing face masks on toddlers are all in Blue States.

Young children, who are at least risk for contracting a serious case of COVID, will also still be forcibly masked, year-round, as will be the staff members who look after them. "Students and staff at PreK Head Start programs are still required to wear masks at all times, regardless of the Community Level," the district policy also notes.

When it comes to other points of the school year, masking is also otherwise "recommended" for students and staff. 

On July 27, The Washington Post published Donna St. George's piece about school districts returning to or considering returning to masking, with many districts in liberal parts of the country. 

According to Burbio, as of August 16, 1.6 percent of school districts, or eight total, require masks. Philadelphia is one of them, as is San Diego Unified, Milwaukee School District, Pittsburgh Public Schools, Jefferson County in Kentucky, New Haven School District in Connecticut, and Prince George's County Public Schools in Maryland. 

I’ll go out on a limb here, and suggest that the teachers and the administrators are looking for something to explain their dismal performance record, and masks are a convenient scapegoat.
