My DD currently at Burford and we have a more mixed view. There are some behaviour issues in her form that upset her and regularly disrupt learning. No worse than any other secondary I'm sure, but not the 'exceedingly high standard of behaviour' I was expecting. She's also had a few issues in corridors with older kids, hates the pushing and shoving in the canteen so won't use it, and they've been banned from their form room several times for bad behaviour.
As others have said, a broad range of extra curricular activities - there is something for everyone. Slight disappointment for us was they can't participate in the 'whole school' musical productions until Y9. Although DD (who's main interests are music and theatre) was in a fab lower school drama production of Arabian Nights last year and they developed her role into a lovely actor/musician role to play to her strengths.
No complaints about the teaching - DD doing well academically and loves most of her teachers.
She loves 'The Acre', the little farm area. It's her safe haven.
Music department is the best in a very wide radius - annual music residential is a big hit here and they always put on a great show.
DD has a couple of boarders in her form and they all seem to love it. We live quite a long way out and might even consider flexi boarding later on if she's still there.
It's a good school, but in this area most of them are. With hindsight I actually wish I'd stuck with our catchment school for a variety of reasons, although mainly due to our very specific circumstances. I think the things that bother her about school would be an issue anywhere, and there are lots of nice extras at Burford that she wouldn't get elsewhere. It's just logistically difficult for us because of where we live and what DD actually needs more than anything is more time for her extracurricular stuff....
