I know this is an old-ish thread but thought I’d chip in, as so much of the very post is massively out of date.
Like the OP, we’d heard great things about the Beacon (including from old friends with boys higher up the school) but obvs wanted to see for ourselves.
On our first visit (2018) we went around mentally ticking boxes: 16 acres of sports fields, all-year swimming (outdoor pool getting a roof), 8 music rooms, 2 theatres (4 LAMDA teachers!), 2 libraries, French/Spanish/Mandarin available from Y1, etc etc… but more than that we loved the sheer energy and enthusiasm coming from the boys. AND they had impeccable manners.
Yes it’s massively pro-sport but in the nicest way (‘sport for all’ policy = six teams for rugby, cricket etc, everyone gets a go no matter how good/dreadful) but we especially loved that drama is just as big (heaps of drama scholarships, inc to the likes of Eton), and also there are loads of other ‘outdoorsy’ activities like open-air art sessions and forest school type stuff. Also: climbing wall, astro for footie, adventure playground (Y1-Y4), and separate playground for the littlies.
But what we really loved is that unlike some of the posters have said, we’ve found that they’re absolutely not a ‘one route only’ kind of school (and there are def lots of those about). Yes they DO send boys off to the trad public schools (and they’re the best school in Bucks for this, if that’s what you’re after... Radley/Eton/Oundle etc), but a big chunk also leave at 13+ for the two local day options (Berko & MTS), and there’s zero snobbishness about anyone wanting to try for Dr Challoner’s at 11+ (the school doesn’t officially prep for it – Bucks schools aren’t allowed to – but they’ll recommend tutors).
Side note: large numbers of small classes means they’re able to do lots of setting (whether for support or stretching). Compare Chesham Prep (no setting until Y5!!)...
As current parents, I’d say the biggest negative is that being such a popular school means the catchment is wide - families as far afield as Great Missenden & Wendover in one direction, or Gerrards Cross & Beaconsfield the other. Plan your play dates carefully.
Hope that helps anyone looking. Feel free to PM me with Qs.
DD is at Godstowe (as are many Beacon sisters).... I would say that while Godstowe is more famous, we’ve found the Beacon to be just as impressive.
