Or rather, when is it measured?
This is very premature but we're about to buy a flat which is about 0.4 miles from what looks like a great school. I've looked at their FAQ and they list the last distance admitted for reception as being 650-ish metres - i.e. 0.4 miles. We're either just in catchment, or just out of it. I get that this will shift year on year.
What I'm wondering - is that the furthest-from-school DC that was initially offered a place and accepted? Those, plus appeals? The furthest-from-school DC who actually started at Reception that year? Something else?
I live in London and there's a lot of movement in and out, so I'm trying to gauge whether we'd be able to join a waiting list and be in with a good chance, or whether this distance already takes into account some waitlisting, iyswim.
