Schools with dangerous concrete race to replan start of term
More than 100 schools in England are scrambling to make arrangements after being told to shut buildings with a type of concrete prone to collapse.
The government gave the order just days before the start of the autumn term.
Some pupils have already been told they will be learning remotely, in temporary classrooms or at different schools.
The government has not said when a list of affected schools will be published, drawing criticism from the Labour Party.
Shadow education secretary Bridget Phillipson, who said Labour had not seen the full list, urged ministers to "come clean with parents and set out the full scale of the challenge that we're facing".
On Thursday, Education Secretary Gillian Keegan said affected schools would contact parents directly, adding: "If you don't hear, don't worry".
Schools found with buildings containing reinforced autoclaved aerated concrete (RAAC) have been told they must introduce safety measures, which could include propping up ceilings.
A "minority" will need to "either fully or partially relocate" to alternative accommodation while those measures are installed, the Department for Education (DfE) has said.
But the DfE has not given a timeline for replacing the material, which was used until the mid-90s.
Ms Keegan said the government was taking a "cautious approach", and that "over the summer a couple of cases have given us cause for concern".
At Willowbrook Mead Primary in Leicester, where arrangements have been made for children from different year groups to attend two different schools, while older pupils will have to use online learning, the head teacher said in a letter to parents: "I appreciate that the timing is far from ideal."
