It's not exactly your choice to make, is it? If she gets in at Tiffin, it's free - you pay for the other two. All three are excellent academic schools. No one 'chooses' one or the other though - it is the schools which choose the child, and the ratio is something like one in twelve for Tiffin, one in six for St Paul's and one in three for LEH.
Why not apply to all three if your child is very clever? Is she Level 5 or more & in 'top group' for everything? If you're thinking of Tiffin, is she being intensively coached?
Finally, where do you live? That is relevant, too, or at least it is for poor so** like me who live around the corner & have to put up with the constant stream of yummy mummies in 4 WDs!
Huntlie - I think the OP was asking about the relative merits of the schools IF , theoretically, they had the choice - which they may well do. the child has already passed one exam and I think her parents are aware of the requirements in terms of preparation.
As for 4WD yummy mummies, yes I am a mummy, not necessarily yummy, but I admit I have been looking at 4WD today - can't stand the ice and snow of the Yorkshire Dales any longer.
Basically anyone who lives near a school (and we live very near 2 GSs) has to put up with a large number of buses (huge catchment area), 6th formers driving and parking
, parents dropping off kids and causing even more havoc, jaywalking local kids ... but hey it doesn't last long and sanity returns by 0900.
