I've read the head teachers post, and I've read the government guidelines issued to schools.
And I know which one makes sense to me.
Primary school buildings in the UK are staffed, designed and equippedfor 30 children in each room. With the best will in the world they can't magically be staffed, designed and equipped to serve the same number of children but with 15 children in each room. That is what he is saying. What is the problem with stating a simple fact.
The government advice was not written by someone who has much insight into how UK state schools operate. It talks for example about moving "desks" . I've been in hundreds of state primary schools and I can't actually recall one where the children sit at "desks", in the UK it is the norm for children to sit at tables, either arranged in pairs with two children together, or in pairs with six children. In most schools there simply isn't the basic furniture available to provide seating and working arrangements for children to sit at two metre distances.
It talks for example about staggering arrival and leaving times. Fine if you only have one child, pretty impossible if you have children in different year groups, and there is only one entrance gate.
I don't think the advice has been written by someone with experience of state schools, and certainly without taking advice from headteacher so.
I really can't see how state schools , who have already in the last couple of months made huge efforts in many cases to deal with new ways of teaching and new ways of supporting anxious parents and children , can now turn around and discover that they can after all, accommodate children in classes of 15, in comfort and safety, with adequate resources ,taught by competent and qualified adults, while also allowing space for children to play safely, eat lunch in a civilised way, wash their hands multiple times a day and be offered wrap around care. Surely if all this was possible state schools would already have been providing it?
