Looks like there's going to be an announcement on school contingency plans
"Other potential guidance that could be issued in a worst-case scenario includes grouping multiple classes together in sports and assembly halls. The department is also looking at "flexible staff models" should absences hit 10, 15 or 25 per cent, but insiders say schools are likely to "tip over" at 30 per cent"
"officials in the Department for Education (DfE) have begun discussing proposals that could see heads asked to prioritise primary, GCSE and A-level pupils for face-to-face teaching should schools be hit by widespread staff absences, with others taught remotely"
If that's true, then I hope they will be looking at having GCSE and A levels at least partly by TAG. Because even if those year groups are technically open, there will be a lot of pupils off (7 - 10 days each, on a rolling basis as infection goes round, with need for hybrid teaching, possibly by a cover teacher - could last 3 or more weeks) plus in some there simply might not be enough staff to stay open at all.
So if we want any hope of a fair system for this year's exams, they can't be exam only. After all, if your DC was at a school that had to shut for 10 days, and had disrupted teaching for 2 weeks either side, would you think it fair when the other school in town had no closure and could afford (and find) supply teachers?
Particularly for A level, as they will be competing for University places with those who had entirely assessed grades and who chose, or in some cases were offered incentives by the universities to defer a year. A step down (hybrid exam/TAG system) rather than full change might be a better way of levelling the playing field for a year group which is already facing the consequences if the unlevel amount of disruption in the previous 4 terms
