Yes, the head is retring.
Good range of extra curricular activities available, there's something for everyone. That said, when we were visting schools two years ago, pretty much every London indie we visited had similar range activities, probably due to competition.
They have the usual sports clubs - lacrosse, volleyball, netball, football, cricket, fencing, gymnastics, cheerleading, karate. Many of them teacher led, other more specialist ones (like fencing or karate) cost extra.
Then there is music/art/performance - choir, singing, drama, LAMDA, jazz, ballet, art, fashion, cookery.
And more academic ones, these are all department led - book club, creative writing, chemistry, zoology, military History, history film , politics, STEM, chess, coding, politics.
Am sure I have missed some, there are probably close to 50 or so clubs.
Also, there's Duke of Edinburgh award at Bronze and Silver level, trips, guest lectures and so on.
It's a small school, only two form year group, so everyone gets a chance to do things - on stage, on sports ground and so on.
That was one our aims when looking for secondary school. DD is shy and had low confidence. In a larger place, she would have happily settled back in the background, passively avoiding participation in most non-academic things. In a smaller place like this, everyone participates.
