Calton Primary School in Gloucester will be closed tomorrow because of an “unexpected premises-related issue”.
The school says it will be closed on Tuesday 13 October.
Staff are working urgently to resolve the issue and put arrangements in place to reopen as soon as possible.
The school says it is hopeful children will be able to return on Wednesday, with a further update due tomorrow.
In the meantime, teachers will provide learning activities through Arbor and Oak Academy so pupils can continue learning at home.
