And the guidance (not the above regs) now says
"All schools, colleges, nurseries and childminders
From 17 May, in line with Step 3 of the roadmap, face coverings will no longer be recommended for pupils in classrooms or communal areas in all schools.
Face coverings will also no longer be recommended for staff in classrooms.
In all schools we continue to recommend that face coverings should be worn by staff and visitors in situations outside of classrooms where social distancing is not possible (for example, when moving around in corridors and communal areas).
Where schools are delivering education and training, including extra-curricular activities and wraparound childcare, in a community setting (for example, library or community centre), staff and pupils will be exempt from the legal requirement to wear a face covering if they are in a private room or the premises have been exclusively hired for the sole use of its pupils and staff.
College students may be asked to wear face coverings where:
the teaching setting is more similar to, or is, a workplace environment
it is a requirement in the workplace or indoor environment and students are likely to come into contact with other members of the public
The reintroduction of face coverings for pupils, students or staff may be advised for a temporary period in response to particular localised outbreaks, including variants of concern. In all cases, any educational drawbacks should be balanced with the benefits of managing transmission."
