Can boarding schools survive coronavirus?

We know of a few private schools (one is a day/boarding school) in our area that have received @ $2-$5 million in PPP money. It was published in the paper. The article posted earlier suggests that those schools with a higher endowment will be ok. One of the big costs this year is the cost of testing everyone on campus and repeated testing - if they are providing that to employees & students. The other costs indicated by the schools who received $ of fed/state/county funds related to paying all their employees while school was closed.
