He said: “Because the tests have to be three to five days apart, and we have to do two of them for all students, we have to recruit additional staff to make this happen as all staff already have jobs to do in September. It is a significant logistical challenge. Students have been home testing for weeks and it is the same test we do at school, so it is frustrating to have to divert school resources on this when there is an entirely viable alternative at the start of what will be the third year to be disrupted by Covid.”
