A mum was almost reduced to tears hearing her daughters ask to wear more layers at school because all the windows are kept open in freezing classrooms.

Clair Jackson, 37, is now having to send Alayla, nine, and Amelia, six, into school wearing thermal vests, extra tights, teddy coats and ear muffs.

The children attend Claremont Primary and Nursery School in Nottingham, which is keeping windows open under government guidance for Covid 19.

Ventilation of school buildings has been a key part of keeping coronavirus at bay, Nottinghamshire Live reports.

But Clair is upset after hearing her two daughters had been cold in their classrooms, with the windows left open as temperatures dropped outside.

Following a spell of wintry weather, Alayla and Amelia had asked while getting ready for school if they could wear an extra pair of tights.

Clair, of Sherwood, Nottinghamshire, said: “It was around November 26 and I think the weather had gone colder, and they asked for more layers.

“I said ‘why? You’ll be red hot’ because I know the school has the heating on. But that’s when they told me they had been really cold.

“When I asked why, they said because all the windows have to be open but I hadn’t even been told about it.

“I felt so bad, I nearly cried thinking about it.

“I think if letters had been sent out about it, some parents might not have brought their kids back or at least if they did, they would have been prepared.”

Claremont Primary and Nursery School is one of many schools carrying out such Covid procedures.

Clair said she raised the issue with the headteacher but was told staff were following Government guidelines and there was not much they could do.

The mum said: “I went straight out and got them both thermal vests, extra tights, teddy coats and ear muffs and told them if they want to wear a coat in class, they can.

“The school said they would try to move them around more, but I think the whole thing is confusing and contradictory.

“They even said they had the heating on high but what’s the point? It’s just going out the window.

“If children have any symptoms, even a normal cold, they have to isolate but surely this can’t be helping.”

Clair questioned why windows being open was not being implemented in other places such as shops.

She added: “Would those working in Government want to sit in an office all day with the windows open?

“I think the Government needs to rethink these guidelines because they may as well be having their lessons outside.”

In its Covid guidance to schools, the Department for Education encourages opening high level windows and allowing extra indoor clothing.

It reads: “It is important to ensure it is well ventilated and a comfortable teaching environment is maintained.

“This can be achieved by a variety of measures including natural ventilation, opening windows – in cooler weather windows should be opened just enough to provide constant background ventilation and opened more fully during breaks to purge the air in the space.

“Opening internal doors can also assist with creating a throughput of air.”

The guidance also states this should be balanced with “maintaining a comfortable temperature”.

Headteacher at Claremont Primary, Robert Campbell, provided a statement on the issue.

He said: “The safety of Claremont children is our top priority and we’ve taken every step to ensure our school is compliant with national guidelines for Covid 19 since our pupils returned in the new academic year in September.

“We’ve worked hard to do everything we can to make sure our school remains open in a way that is safe for everyone.

“This includes keeping classrooms well ventilated.

“We understand the concern about open windows in the winter, but we have taken steps to mitigate this by closing them to a minimum distance, weather permitting, to allow air flow, opening internal doors where possible and by adjusting the heating accordingly.”
