A high school will delay reopening after 14 classrooms were identified as having reinforced autoclaved aerated concrete (RAAC). 

Claydon High School sent out a letter to parents this evening setting out the provisional arrangements for the start of term as it searches for temporary classrooms. 

Last week, the Department for Education (DfE) told schools to close buildings that are constructed with RAAC over safety fears and has identified four schools in Suffolk. 

The school will bring three year groups back on Thursday and three back on Friday before issuing further update about the following week. 

Years 7, 10 and 11 will return on Thursday.

On Friday, years seven, eight and nine will return to the building with years 10 and 11 issued with home learning - but this will not involve remote learning. 

The letter sent by Sarah Skinner, CEO of Penrose Learning Trust and Maeve Taylor the headteacher of Claydon High School said: "We have 14 classrooms and some communal areas that we are not permitted to use. This means that we will not be able to open to all year groups until we have procured temporary classrooms and re-timetabled lessons to make use of all available space in the school.

"Whilst we are sure this is disappointing to hear, the fact that the problem is confined to one building means that students can still move around school safely.

"We are currently working to secure temporary buildings to allow us to fully reopen. However, we will not know until early next week whether classrooms are available or when they could be delivered and set up. As soon as we have further information, we will update you.

"We aim to have at least three year groups in school at any one time until temporary classrooms are in place, however until we have re-timetabled we cannot be certain that this will be possible. We hope to be able to give you a further update on Monday or Tuesday at the latest."

The trust reassured parents full surveys have been completed of all of its schools a full plan of work will be undertaken as required by the DfE.

The letter continued: "On behalf of the Trust, we would like to apologise for the disruption. The start of a new school year should be full of excitement, positivity and a celebration of the great results achieved by the school over the summer. Instead, we find ourselves scrabbling to ensure we can get all the students back to school as quickly as possible.

"It is the sudden change in policy that no area can be used, regardless of whether the survey found the concrete to be unaffected, that has created the problem."

Other Penrose Learning Trust also identified by the DfE is Hadleigh High School and East Bergholt High School.
