More than 100 schools in England have been told to partially or fully shut buildings amid safety concerns over the concrete they were built with. The BBC went inside one school that has already had repair work done to find out what lies in store for others.
Inspectors from the Department for Education arrived at Springfield Primary School in Chelmsford four weeks before the summer term was about to end.
Their visit followed revised guidance released in April about schools built with reinforced autoclaved aerated concrete (RAAC).
As a result of the visit, the junior school section of Springfield Primary had to close overnight.
"Obviously the school had to move into overdrive to find additional accommodation for about 180 children," Mike Mackrory, the governor responsible for health and safety, said.
"Fortunately it was towards the end of the summer term."
