My dc at secondary haven’t gone back yet (tomorrow and Tuesday), but I’m not really expecting social distancing.
Dd1 is at a SN school, and they have already staged it isn’t possible to social distance. She was at school part time for the whole of the summer term, and the same then too. It just isn’t possible, given the structure of the school and the assistance needed by all the pupils.
Dd2’s school are able to spread out a bit more, and I have had a very thorough document through about year groups and areas - it’s a private school so the pupil/space ratio works in their favour. The year group bubbles will be as separate as possible, but there will be be obvious bottlenecks. Again, these have been thought out as much as possible, but there will be crossover. It is inevitable. And then of course there is the whole bubble issue anyway. Dd2 has 70 odd in her year (I realise this is far less than most secondary bubbles), and while they have reduced movement around the school (staff moving rather than children), it still has to happen sometimes - lunch, PE, some specialist lessons.
It is what it is. I known there won’t be social distancing, but I had to confront that early on with dd1 going back to school after Easter.
My youngest is back (primary), and again while the year group is reasonably well isolated, pick up at the end of the day results in different year groups standing side by side for collection, even with staggered collection times. And after school care gets widened, so ds is in yr4, but after school care is yrs3-5, so suddenly his bubble of 60 becomes a different bubble with the same number (ish), but from 3 different original bubbles.
