Several schools may have to shut or partially close following a new government announcement to shut down buildings constructed with aerated concrete.
More than 100 schools, nurseries and colleges in England have been told by the government to close classrooms and other buildings, including Hadleigh High School, East Bergholt High School and Claydon High School.
All of the schools are under Penrose Learning Trust, which confirmed the news on Friday.
Sarah Skinner, CEO of Penrose Learning Trust, along with each of the school's headteachers released a statement to parents.
The trust said the schools will need to consider delaying reopening or partial closure until the issue has been resolved.
The letter continued: "We will update you either later today or Monday as to whether we need to delay reopening and/or move partial opening. We are sorry that we cannot provide more details at this point in time. We are hoping to have surveys completed over the weekend which may change the situation and would rather you receive one communication regarding opening."
A spokesperson for Suffolk County Council said: "We have been actively seeking further details from the DfE.
"The key is to get a clearer picture of the impact on any schools affected ahead of the start of the new academic year, so that mitigations can be put in place urgently if all or parts of buildings cannot be used."
A month ago, Jack Abbott, Labour and Co-operative Prospective Parliamentary Candidate for Ipswich, urged the government to review school buildings across Suffolk after it was revealed that nearly 300 schools in the region had at least one part of their buildings needing repair or replacement, with more than 3,000 items found to be defective.
Mr Abbott said: "More than 100 schools across the country have been told they must immediately shut dangerous buildings.
"Coming just a few days before the new school year starts, it will cause severe disruption to children, their families, and their schools, and begs the question, what on earth has the government been doing all summer?"
