It’s tricky! I would say it depends on part on how old your eldest is and when they’d be moving up to secondary. There are two very popular/high achieving secondaries in St A, Beaumont, which people from Fleetville have historically attended, and Sandringham which is up in Marshalswick.
Over the last 8 or so years two large housing developments have been built on land adjacent to Beaumont, meaning people in Fleetville have been squeezed out of catchment. Last year there was a real crunch as Beaumont initially dropped what had been a temporary bulge class and catchment shrank from c.900 m to c.550 m, as lots of people from the new developments filled the places. There was a big hoo ha and the school in the end permanently re-added the bulge class.
But there is still something of a black hole meaning the only schools you can hope for are Verulam (all boys, an ok reputation but not massively popular with St A families), possibly STAGS (all girls, good reputation but quite a trek from Fleetville) or Townsend (CofE, not a great reputation and an even bigger trek). Marlborough is a possibility but again a schlep across town.
That said, a number of people managed to get Samuel Ryder on continuing interest which has a reasonable reputation but again it’s quite uncertain whether you’ll get a place unless you live that side of Fleetville.
Things may be ok for the next 3-5 years (ie most people will get Samuel Ryder if they don’t get Beaumont).
However, to add to the uncertainty there are plans for absolutely enormous new housing developments near Beaumont and near STAGS, and currently no provision for any new secondaries! So in 5+ years we could have another big crunch point! 😬 And the added difficulty with the new developments is that school rush traffic is already awful so with lots of extra houses I fear St A could become unnavigable by car 😞
I definitely don’t want to put you off Fleetville though as we do really love it here. But what a number of people have done is move from here (eg Burnham, Brampton, Woodstock, Glenferrie) further East to be nearer Beaumont and be sure of being in catchment. To be safe you’d want to treat the southern end of Beaumont Avenue as the boundary of the catchment for Beaumont and be East of that.
There is still a very active WhatsApp group a year later discussing the issue of secondary places this side of town!
An alternative would be to focus on Marshalswick and Sandringham but if you need the train station it’s not really walkable, unlike Fleetville.
