Boris Johnson’s government is expected to announce the phased reopening of schools as early as next week, with March 8 slated as the target date for reopening. The Telegraph reported on Thursday that secondary school students will be tested en masse once classes begin, and parents will be asked to test them twice a week at home from then on.

The Department of Education did not confirm or deny the report, which came ahead of a meeting between department heads and teachers’ union bosses on Thursday. Talks between the department and the union are expected to focus on how to implement a testing regime. The unions have pushed for at-home testing, and according to the Telegraph they called on-site testing “inoperable” and “ridiculous.”

However, commenters online immediately shot down the idea of at-home testing. One pointed out that the lateral flow tests that would be used have a false positive rate of 0.32 percent, which would generate 6,400 false positives per week, assuming one million secondary school students are being tested. If every one of England's 3.4 million secondary school students are tested, more than 20,000 false cases could be reported every week.

Another Telegraph report this week stated that the government will not ease lockdown restrictions until new coronavirus cases dip below 1,000 per day, a target that would likely be impossible to meet if so many false positives were being reported.

A study by Imperial College London, published on Thursday, found that infections across England have fallen by two thirds since January, but the country is still recording around 10,000 per day – ten times the government’s supposed target.

Aside from the glut of cases – both real and false – that such a testing regime would bring, some commenters said it would be “unenforceable and unreliable,” while others simply balked at the “cruel and unnecessary” idea of subjecting their healthy children to non-stop testing.
