Totally agree with you Firefox1066
My DS1 has just started W in Y6. Though it's not announced that 'X' or whoever is on any kind of scholarship, the boys soon figure out who are. But what is clear, is that they are not treated differently to the ones who aren't on a scholarship.
Boys are really encouraged from day one to try and do as many co- curricular activities. This helps to engage and make new friends, introduces them to subjects they have never tried or wouldn't have dare tried in the first place. The old head master always used to emphasise that a busy boy is a successful boy. And I do believe that there is a lot of truth in that.
At W there are boys that come from quite far, but thus equally local to. This is the same for T and other indie schools. You've got to remember that the school will be taking in boys from all walks of life and that's just not locally, and not typically of what you'd expect from you local primary/prep school.
Though we were explained that they like to weed out the ones who are likely to distrupt the other boys and teacher, learning in general, they don't always get it right. But boys who don't perform, misbehave are dealt with accordingly. And not only can the scholarship be taken away for bad behaviour or poor performance, I've heard that if they really misbehaviour very badly they can withdraw your place.
What I'm trying to say is that both W, T and other indies are all very good schools academically, providing excellent eduction, activities, trips etc. Depends on your DS what they're like and if and how they would fit in that particular school is what you've got to go on.
At the end of the day, academically they're all fantastic, but no matter how good the school is, the bottom line is if your child doesn't put in the hard work which is expected, and don't behave. Then it really doesn't matter what school they go to, indie, grammar or state.
And one more thing, my DS along with a few more boys from Y6 and Y7 were invited to see the headmaster. This wasn't just because they've done well academically, but this was on everything, behaviour, but most importantly effort. What was clear from his message was that effort and behaviour are very important, and the results/grades will come if you put in the effort. As some kids who don't, because they think they're clever and don't need to put in the work become complacent and results dip. Apologies for going on!
