A junior school has been closed after a building surveyor identified "urgent concerns" with some of its ceilings.
The survey at Avenue Junior School in Norwich was taken on Tuesday night following concerns raised about other Norfolk schools of a similar age.
Head of school Mike Hooper said the decision to close was "to ensure everyone’s safety" and the school was working closely with Norfolk County Council.
Norfolk County Council said the school was closed "as a precaution" and it was liaising with the school to minimise the impact on the pupils "as much as possible".
In a letter to parents, Mr Hooper said: "During the inspection, urgent concerns were identified relating to the ceilings in several rooms.
"Consequently, there now needs to be a thorough investigation of ceilings across the building."
He said he understood "the inconvenience this closure may cause".
The school, which takes children from Year 3 to Year 6, hopes to update parents by 15:00 BST "with the latest information about the situation and our next steps".
A county council spokesperson said it had called in surveyors following the issues detected in Synergy Multi-Academy Trust’s schools.
She said: "This has identified some concerns about ceilings at Avenue Junior School and the school has therefore closed today as a precaution.
"We are working with the school urgently today to make plans for the children’s learning, so that we can minimise the impact as much as possible.
"We apologise for any inconvenience, but the safety of the children has to be our priority.”
Fakenham Junior School and Reepham Primary both had to close some classes at short notice earlier this month over structural problems with their ceilings.
