You won't be- though in my opinion, there should be 'cut off' points: ie a DC in say reception whose parents move should have to vacate their place IF there is a waiting list at the end of Y2, or Y6, and perhaps Y9?- whichever is the next 'point' along.
It would stop that iniquitous practice of 'renting in' especially fraudulently (the six month rented one bedroom flat IN catchment you leave vacant whilst YOU live in 5 bedroomed luxury elsewhere- in a house you couldn't or would choose not to afford IN catchment).
I am always 'amused' by London folk, in particular, who buy 'big' in a given, less desirable area, then once the DCs reach school age, lament loud and long, their song of entitlement, demanding that space be made available to their DCs in the more desirable, possibly more expensive borough's schools next door.
There is also the issue of (tax payer subsidised) private school places: the idea that if a fee paying parent suddenly gets into financial difficulty, it should be UNTHINKABLE that the private school advantage be withdrawn from their DC!- and perhaps passed to an 'outsider' who would never had gotten a full fee place in the first place. That sense of entitlement, again.
OK, in the state sector, I KNOW it's 'selection by catchment'- but if indeed we have that system, let's enforce it. It keeps the school community 'local' and allows a person who buys in the area to also be getting a local school place, not be kept out by someone who lives MILES away.
You pays yer money, etc.
