They sent home some of my DD’s year group earlier this week. I’m CEV and asked the school if she could also study from home (because last time this happened there were a few new cases in the days after the first one, and I didn’t want her about potential incubators
Fortunately they said yes, which has been a huge relief
I would put all secondaries onto online working now, with premises only open for DC who have particular need to attend (inadequate home tech or whatever)
Keeping working until the very last day is important for those in years 10-13, but that’s also the age group who ought to be able to work effectively online without parental input
