Currently looking at local state sixth forms. One of them has a (self-seeded) reputation for being "the next best thing to a private school, without the price tag". Bold claims, glossy brochures and aggressive marketing, which makes me instantly suspicious.
One thing that jumped out at me from their website (for both the secondary and the sixth form) is that they use the term prep instead of homework. Is this not a very self-conscious, wanky move? This is a college that was only built ten years ago, so it is clearly a deliberate choice rather than a long-standing tradition.
It feels subtly exclusionary class signalling to me - like they don't want to attract the kind of families that don't know what prep means.
