No Jim. It's the government's responsibility to set policy and provide the funds. The organisation of education is done by those providing it - i.e. the schools. It's the same as with health - healthcare is "organised" by the healthcare trusts. The clue is in the name. The education policy (in England at least - I'm none too fussed what happens in the minor constituent areas which suffer devolution) should have been "The schools will return to work on dd/mm/yy. Get on and organise it."
//I work in the Sixth Form of a large secondary school, and at the moment I am emailing students with lessons that they have been timetabled to do. It's been a bit of a nightmare for the staff involved to arrange, what with one way systems around the school, staggered starting times, arranging skeleton staff to coordinate the students when they do come in, and also make sure that they are adhering to the COVID H&S policy etc. and that's on top of the usual work that has to be done. To try to do that for 1700 students would be nigh on impossible.//
Welcome to the world. Managers in industry, business and commerce have to tackle problems of equal complexity on a daily basis. They do so without closing down their businesses for six months. The supermarkets managed to put arrangements in place to comply with lockdown rules and guidance within a matter of days - less than that in some aspects. It wasn't perfect to start with (and still isn't in many ways) but it works and most people are able to get most of their goods. The education "industry" has had three months to prepare for resumption. It isn't ready and suggests it may not be so in another three (by which time most of the restrictions they have been preparing for are likely to have been lifted). I'm afraid they need a kick up the jacksie.
