The number of education settings with collapse-prone reinforced autoclaved aerated concrete (RAAC) has risen.
An updated list from the Department for Education shows that a total of 174 education settings in England have RAAC present as of September 14.
The original list - published in the first week of September - showed there were 147 schools and colleges with RAAC as of August 30.
The updated list suggests 24 schools in England have had to offer some remote learning because of RAAC issues.
Of the 174 education settings confirmed to have collapse-risk concrete, 148 are offering full-time, face-to-face learning to all pupils.
Gillian Keegan, the Education Secretary, said: “We are taking a cautious approach so every parent in England can be reassured their child is safe in their school.
“School and local leaders deserve huge credit for making sure the vast majority of settings with confirmed RAAC are continuing to offer pupils face-to-face learning - including all of the 147 schools initially identified two weeks ago.
“We will continue to work closely with affected schools and provide both expert and financial support to minimise disruption and keep staff and children safe.”
