Peter Weir denies that he is ‘following Scotland’s lead’ over face masks in schools

Mr Weir said the decision to advise post-primary schools that masks should be worn in corridors and communal areas was taken after scientific advice on the matter.

He told the BBC: “On the specific issue of movement around schools and in corridors they felt an additional precautionary move should be taken to add to the advice, I suppose, reflecting the developments in terms of what is now widespread best practice.”

Mr Weir rejected the notion he was simply following Scotland’s lead and added “as time moves on and our understanding of how best to deal with the pandemic develops, there is likely from time to time to be some changes”.

The official guidance to limit the spread of coronavirus comes into effect on August 31 when schools return on a full-time basis.

The DUP minister said it was not a replacement for frequent hand washing, social distancing where possible, covering your mouth and nose when you cough or sneeze and regular cleaning of surfaces.

Face coverings are not recommended as being compulsory for routine use in education settings.

However, staff and pupils may wish to use them during the routine school day and this is acceptable, the minister added.

The first year groups returned to school on Monday for the first time since lockdown began in March amid trepidation from some parents and teachers.

Sinn Fein’s former education minister John O’Dowd has said the decision to recommend the wearing of face coverings in school settings should have been introduced with immediate effect.

He added: “This latest move by the minister is yet another example of lack of clear decision-making and guidance from the education minister which has caused confusion for parents, teachers and students.”
