FFS.
People have been complaining on MN that they want testing in schools for weeks.
They haven't rolled it out into schools until now because they've been trialling how it will work in a few schools in different parts of the country.
My DC school have been part of the trial: lateral flow tests for whole school weekly, then if someone tests positive, if close contacts were negative the same day, they keep coming to school and get daily tested.
If a cluster emerges (often asymptomatic kids) they work with PHE to decide whether to SI a class/year group.
So far this term my DC has had a total of 0 days SI. They've had to send 1 year group home once. No school closure (unlike many local schools)
Test results take 15-20 minutes. Any unclear results are retested, and some also get PCR.
We had to give consent, and could withdraw consent at any time.
I have had no complaints at all. Staff seem to be very positive- they've kept far more kids & staff at school compared to other local schools.
