What does in-person school look like in the COVID-19 era? Here’s a look inside.

The first big yellow school buses rolled up at 8 a.m., and a handful of students stepped out into the September sunshine.

The school doors swung open, and one by one, a line of kids entered Nativity of Our Lord School in Warminster, each child’s hands reaching out automatically for the first squeeze of hand sanitizer of the day. The students had been spread out on the bus, and were careful not to get too close to one another on the way in. They all wore masks.
