How they are not having to send children in with a mask on.
Secondary school children are entitled to refuse masks and CV19 tests and must be allowed into school without either.
"Children are not under any obligation to wear face masks, the Government said on Wednesday night, telling schools not to send pupils home if they refuse to wear one.
While masks and regular Covid tests are strongly encouraged, they are not legal requirements and pupils should not be "denied education" as a result of non-compliance, officials said.
This week, Boris Johnson announced that secondary school students will have to wear masks in the classroom when they return if it is not possible for them to keep two metres apart.
Pupils are also being asked to take four lateral flow tests during the first two weeks of school, three of which will take place at school and one at home. After that, they will be asked to take two tests per week at home and report the results to their teachers.
But ministers have said both these measures are voluntary and pupils must not be kicked out of classes if they refuse."
