Yes, I agree.
Voluntary aided schools are "maintained" - they received their funding dollops from the local authority, not central government, so they are (not yet) supposed to put adults who are not working towards QTS in total charge of classes. It is very grey though.
It must be very hard for worriedmum to know how this new secondary element to the school is going to develop ... . But there's risk with any school that you choose.
Do its longer term plans sound good worriedmum? Is it going to be 11 to 18? Do they have all the necessary permissions? Does it have a good headteacher with a good track record at secondary? Similar for the Governing Body?https://www.gov.uk/government/publicati ... ed-schools
These publications show you what a maintained school should do when it changes its age range and who can do what.
