happygardening I assure you I'm not "upset", just cross. And I worry for parents who are doing careful sums like OP when there are other things to be looking out for.
Independent schools keep pretending they're trying to help parents with fees but, as you have acknowledged, they just don't have the necessary funds.
A few weeks ago The Times carried an article about Westminster Harris Sixth Form and quoted the head of Westminster School saying he couldn't tell the difference between the pupils at the two schools. When the journalist, herself an Old Westminster, queried this bizarre statement, Mr Derham replied that Westminster School was becoming "needs blind". This is palpable nonsense.
Likewise you tell us that Win Coll is "hoping" to sell some land in order to build a "needs blind" fund. It hasn't done so yet, though, has it? Again, fine words but no action.
Actually, I think selling the Mappa Mundi would be an excellent idea. The govt would have to buy it one way or another. A big fund for "needs blind" admissions would be much more in line with William of Wykeham's plan for the school than turning it into a tourist attraction.
It depends what your priorities are and what you think is important. Andrew Halls of KCS Wimbledon recently told a BBC documentary that The Tatler Schools Guide was "important". It isn't. The founders of that great school would be appalled.
It was so revealing because this was the same Andrew Halls who'd told the Sunday Times that he'd just realised his fees were becoming unaffordable for numerous professionals. Oxford dons kept telling him that when he took MCS on its stratospherically expensive route to "Sunday Times School of the Year" but he wasn't listening then, probably because he preferred to spend his time reading Tatler.
