My kid‘s independent private Catholic school is open and has been open all year, They make the kids wear masks, put up makeshift plastic barriers at kids desks, now test weekly and my kid is doing great. frankly. You wouldn’t know the difference from pre COVID, but for the lack of direct interaction.
Amazing Faculty, caring administration, and yes we pay tuition for it but frankly I (and we) pay for public schools (through taxes) as well, so why can’t public schools get it together in my neck of the woods.
