Our school is still opening in August for face-to-face instruction-- offering an online for 4 weeks until late September as well, but will have to be rigorous and the school has made it clear they expect the online kids to keep up with the face-to-face instruction and there are no tuition discounts for choosing online.
At pick-up and drop-off (obviously no buses) kids have temperature checks both in the AM and PM, Mandatory masks, no sharing of learning tools, toys, games, etc., no cafeteria food (must bring brown bag lunch), mandatory social distancing, and a souped up hygienic schedule for both facilities and baked in times for kids to wash/sanitize every hour.
The classes already have an 8-10 student to teacher ratio in normal times. I expect it to be smaller in the fall, though my wife thinks there might be a run on parents getting their kids into moderately priced private schools like ours, which would be horrible for social distancing and keeping the low ratio, as they fall outside of the jurisdiction as AG Ken Paxton ruled.
Let's see.
