Do you really think that nobody is going to figure it out? What happens when they do?
There are two benefits to going under the radar. If there is limited Covid activity the school can continue uninterrupted. Even in the event the kids end up testing and come back with positive results, a Lakewood school with the covid numbers that YDT had would likely send those specific classes home for a week or so, and allow the hundreds (or thousands) of other students to continue to learn uninterrupted.
If someone “figures it out” they are no worse off than YDT.
