Pupils have been swabbing themselves as school nurses watch on despite proof rapid tests only work if they are administered properly.
Students at Oasis Academy in Coulsdon, Surrey, were sent the kits on Monday and given instructions by nurses on how to carry out the tests themselves.
Only vulnerable children or those whose parents are key workers are allowed to attend lessons in person during the latest national lockdown. It comes as figures suggest schools could still be attended by up to 20 per cent of pupils.
But children are now being supervised by nurses, similar to how some walk-in testing centres are run, rather than having a nurse carry out the tests themselves.
