In Wales pupils and staff who will be identified as close contacts of infected persons will be allowed to continue going to school or college.
Under Welsh Government`s new plans, close conducts from a positive test will either self-isolate for 10 days or take a lateral flow test at the beginning of the school day for the duration of their self-isolation period.
Training for school staff is set to begin this week and continue in January and testing would not be compulsory, Wales’ Health Minister Vaughan Gething said.
However, testing by itself “cannot eradicate the risks associated with contracting and transmitting Covid-19,” he said.
“Testing… needs to be taken alongside other infection prevention control measures, including appropriate social distancing and hand hygiene measures.”
Some scientists have raised concern that people could start disregarding health advice after a study found that the NHS Test and Trace test missed 50 per cent of cases
Eithe Hughes, director of the Association of School and College Leaders in Wales backed the idea of reducing the number of people isolating but expressed questioned how it would work.
Ms Hughes said: “Then I’d be wondering about why I’m hearing about policy on the media in the last week of term when there’s already so much else to be done.
“Then there are some questions around the logistics of actually carrying out this mass testing in essence… if it’s a large secondary school and you’ve got multiple year groups involved, what does that look like for a school every morning for 10 days?
“Then again, if there is a positive, and additional contacts considered, does that mean the process starts again for another 10 days?”
The Welsh government has pledged to give the necessary support, equipment and training to schools and colleges to enable weekly teats to be conducted.
