Interesting thing that came up the other day. My Primary teacher DH had a kid off school with a non-Covid illness and the mum asked for the lesson links and the home school material - which is obviously available in case of self-isolation. DH provided it but then wondered if he should have. He checked with the Head later and the school policy is not to - the Head said, if they are well enough to do the work at home, they are well enough to come to school, and feels they need to be wary of setting a precedent. In a way though, Covid has already set the precedent!
I think it is a really tricky one. On one hand, it would be super tough on teachers for this to become normal practice - that they have to provide full curriculum for any child who is off school at a moment's notice. But on the other hand, why does a child who is home with a positive Covid test get access to education while a child with a cold or chicken pox or whatever doesn't?
