A few weeks out of a school career honestly won't make that much difference
Is it just a few weeks though?
My one year 10 son has not been in school for 42 days since Sept, my other year 10 20 days, due to high cases of Covid at their respective secondaries.
This is in addition to the initial March to July lockdown.
Remote learning was a mixed bag during lockdown and in my one son's first two out of six self isolations from school, we had days without any lessons whatsoever, before Ofsted guidelines re remote learning were introduced.
My year 10s have actually missed months of in-school learning in a GCSE year, not just six weeks. There is simply no time to catch up.
A seemingly endless cycle of self isolations have now dominated my home for months and while I do believe that a temporary closure is the lesser of two evils for US, the missed education in school is not minimal, sadly.
