What I don't understand is that at my DD's school they have put together both nursery and Reception kids in the same class, with a total of 15.
If the goal is to have as less kids as possible together to minimise risk of transmission, why do they mix two different groups? If they were each in the classroom they used to be, there would be two groups with only 7 or 8 in each, better than a group of 15. Defies the purpose
It's because schools are under a legal obligation to provide both in-person and remote education - with no extra money.
Half the reception class and half the year 1 class are in.
Two teachers; one takes the children that are in, the other takes the children that are learning remotely.
The purpose is childcare to allow key workers to work, it isn't about keeping the children or their parents any safer.
