Crumbs, I can't believe the problems people have, it's so simple and stress-free here.
Our two main schools (the 3rd is right at the other side of town and no-one from our primary school goes there), are literally next-door to each other - their playing fields actually merge.
There are no catchment areas as such - everyone who lives in the town proper is in the catchment area for both. People from outlying villages are technically assigned to one school, but this only comes into play when schools are heavily over-subscribed, and the village children still have priority over children from other towns.
No catchment area by house prices either - because it's everyone in the house it doesn't matter if you live in a council house or an executive detached home.
Because of where the schools are, right next door to one another, some parents let each child choose and end up with children at both schools.
Both schools are good. One is perceived as better academically - in the top dozen or so comprehensives in the country, and on Ofsted's honours roll of the best of the best etc - but the other is still good. Both have nice atmospheres and strong sport, music etc. I would have been happy with either.
We only put one school down for our eldest, no 2nd, 3rd or 4th choice, because we knew that living in the town meant it was almost impossible for her to be refused a place. For no. 2 we did the same - he had even more chance because of the siblings-first policy. We'll do the same for no. 3.
My sympathies to all of you for whom it's obviously more of a palaver. It just sounds so alien to me.
