But education chiefs hope schoolchildren will only have to wear their face masks in class until Easter - with measures lifting during the summer term.
Amanda Spielman, the chief executive of Ofsted, said Brit youngsters are "adaptable and flexible" - but admits she hopes masks and testing will be gone from schools soon.
On Tuesday, the Government intervened to stop councils requiring children in primary schools in England to wear face masks.
The move came after it emerged that Redbridge council in east London had advised headteachers to consider face coverings for primary school pupils in the borough as part of Covid health and safety measures.
New Government guidance for pupils returning to school next week states that children in primary school do not need to wear a face covering, but “recommends” that secondary school pupils should wear masks in classrooms without making it mandatory.
It means there's no legal power to enforce mask-wearing.
Education Secretary Gavin Williamson this morning backed the measure, and said children deserve credit for their efforts to keep friends and family safe.
Meanwhile, Mr Williamson has said summer holidays could be slashed with a five-term year and longer school days in the biggest reform since the Second World War.
He gave the biggest hint yet that the six-week break could be cut in an interview this morning.
The embattled minister, who has the lowest rating of Boris Johnson's cabinet, said the idea was being reviewed by the Government’s education catch-up tsar Sir Kevan Collins in the wake of the coronavirus pandemic.
Asked about the plans by Sky's Sophy Ridge, he said: "It's whole range of different proposals, the five-term year, lengthening of the school day, but also enhancing support to teachers and making sure they can be the very best of themselves."
Pressed on summer holidays, he said: "We're looking at holidays, we're looking at the length of school day, a whole range of measures."
