I absolutely would not do this.
Would you let your solicitor test your children? Or the manager of your local Tesco’s? Or a police officer?
Fortunately I work in a school which a)knows better than to suggest we do this b) is fortunate enough to have in house nursing staff and money for overtime.
I still expect the tests to have a very high failure rate and be worse than useless in containing the continuing inevitable spread.
But the govt get to ‘try’ this for half a term or so and then wide eyed look surprised when it’s failed and hope to goodness they’ve managed to vaccinate enough people to get the hospital numbers down by then. All whilst appearing to be ‘doing their best’.
