Department for Education officials said surveyors had been checking hundreds of schools every week for RAAC.

The total number of schools impacted has risen 18% to 174 in the two weeks since the crisis started after the DfE changed its collapse risk rating.

Just one education setting remains fully closed with all children in remote learning, down from four two weeks ago.

Twenty-three settings are now providing a mix of face-to-face and remote arrangements, up from 20 at the end of August.

Every setting on today’s list has already been assigned one of a team of 80 case workers plus project directors working with schools on the ground.

To support local teams, the DfE confirmed it had contracts with three leading suppliers of temporary accommodation to provide temporary units.

Last year, the department issued a questionnaire to responsible bodies for all 22,000 schools in England to ask them to identify whether they suspected they had RAAC.

The DfE said that it had now received responses to the questionnaire for 98.6% (95.5% at 30 August) of schools with blocks built in the target era.
