If you like it or not, the job has been stated by government as ‘childcare’ so if they are providing this, they are doing their job.
I think this is at the heart of the 'patchiness' of provision.
Emergency childcare in school was a really early announcement, as soon as the schools were told to close.
Since then, provision of home learning has developed, both nationally (BBC Bitesize, Oak Academy) and within every single school.
However, the original announcement on school-based childcare provision HASN'T changed or developed to keep in line with this. Where the childcare is based in a single school, for that school's children and supervised by that school's staff, provision for the home learning may well have developed along the same lines as the home learning for other pupils. Where there is a hub, or where some primary schools have stuck very closely to the original line of 'in school childcare is just childcare', or even where different children are attending every day so spending a minority of their week in school, there may well have been less of a change.
So in fact, schools where the 'daily childcare' includes daily completion of home learning tasks are doing 'more than their job', rather than schools doing pure childcare doing 'less than their job', if that makes sense?
