Concrete that could be at risk of collapse has been identified in another 17 schools and colleges in England, the government has confirmed.
An update from the Department for Education (DfE) said the reinforced autoclaved aerated concrete - known as RAAC - had been found in the buildings, bringing the total to 231 as of 27 November.
In addition, one setting - Abingdon and Witney College - was recorded as a new case and an assessment is being carried out, the DfE said.
The list suggests at least three secondary schools are providing a mix of face-to-face lessons and remote learning as a result.
Bramhall High School in Stockport, Greater Manchester, St Thomas a Becket Catholic Secondary School in Wakefield, West Yorkshire, and St Clere's School in Stanford-le-Hope, Essex, are all offering some remote learning.
The last update from ministers in October set the number at 214.
