What is the age limit for children still being sent into school?

[Grumpyoldpersonwithcats]

Surely there should be a cutoff? (13 or 14 maybe?)
Do for example the 17 year old children of key workers still get a school place in the new world order?

Just curious.

Some SEND pupils are 16 and 17 so that has to be taken into account too.

I hope those that are vulnerable, or with EHCP needs that mean it's the right thing to continue at school, can go with no age cutoffs.
The schools opening isnt just about childcare.
