Announced today are 4 additions to the RG Group of Unis, Durham, Exeter, Queen Mary, and York. They were all previously part of the 1994 Group.
They all had a good reputation to start with and are not likely to be doing anything differenty at all, but presumably they think this will make them seem better.
So the question remains as to if any 'uni associations' which confer status really based on any actual superiority or just self-imposed hype.
Having taught within a range of institutions (including RG) I think that that it is definately the latter.
