Just that really - deliberately not being too specific about our own criteria, but wanted as much of a cross section of opinion as possible. Having crossed Winchester off the list after visiting (great for some, I am sure - but not for us and just could not imagine DC1 being happy there), it now looks likely to come down to one of these two...
A friends DS who is at Oundle was told when he sat CE a couple of years ago that it was 60% cant remember if that was on all papers or maybe just the core subjects. Interestingly he was well off that mark in one of the core subjects but still got in.
Gunz - I think both schools have a nominal CE pass rate, but only to filter out those who really couldn't cope - they both put more emphasis on reference from current head and interview. DS would be going through scholarship exam route for either, so I didn't pay too much attention to what those nominal levels were - sorry.
Oakham is a fantastic school. I am an OO. PM me if you want more details but I would send my kids there without hesitation. The Good Schools Report sums it up perfectly. If you want a well-rounded, well educated, polite and erudite child Oakham is for you.
