Two Suffolk schools have joined the list of education establishments built with aerated concrete, bringing the total up to nine in the academy.
Schools in Suffolk and across the country were plunged into crisis earlier this year after the Government revealed reinforced autoclaved aerated concrete (RAAC) was present in some schools.
It is now known that nine establishments in the county have been affected by the crisis.
The latest Department for Education list shows Stour Valley Community School in Clare and Brandon's Glade Academy are affected.
Pupils at both schools remain in face-to-face education.
Newmarket Academy, Hadleigh High School, Farlingaye High School, Claydon High School, East Bergholt High School and Thurston College are also listed as being affected by RAAC.
Thurston College has resolved the issues at its site, while Farlingaye High School has erected temporary classrooms after a third of the school was closed off.
Penrose Learning Trust, which runs Hadleigh High, East Bergholt High and Claydon High, also implemented temporary classrooms.
A total of 231 premises have now been affected by the crisis, according to the Department of Education.
