I see no point in sending schools back in the last few weeks of term. May as well keep them off
Reasons for going back for a couple of weeks:
Children that are leaving get to say goodbye and round things off.
Children get to touch base with friends and teachers and feel reassured that everybody's ok so they can relax a bit and enjoy their summer.
School staff get a chance to spend time with kids and check that there are no concerns about home life before the summer holidays begin.
Children in abusive situations have a chance to confide in somebody.
Parents get some sort of respite if only for. Couple of weeks.
(All mental rather than physical health considerations but they still matter)
Plus, it gives the govt a chance to see what letting children mix does to the figures in a controlled way because they have a natural break after a couple of weeks anyway.
If all seems well then permission could be given for some small group childcare schemes to run over the summer which will mean that parents can work and this will support the economy.
I'm a teacher and despite some minor health concerns I'm hoping for two or three weeks in school before the summer begins for those reasons.
