I can see why a catholic school might care if their students are catholic, but i can't see why they would care where you live, seems absolutely irrelevant to me.
Hm i'm not too sure, because where I'm from there isn't much variety haha and everyone generally goes to the closest school, buuuut, if schools did select on academic merit, wouldn't that mean there would be students who would miss out on going to a school close to them (because they weren't smart enough) and have to travel ridiculously long distances/move just to get an education?
that might be the case, but that is still better than selecting on location. what's worse? selecting according to postcode or on academic merit (like MHS and MacRob)?
If you believe in equality of opportunity you cannot support school zones:
"How Much Do Public Schools Really Cost? Estimating the Relationship Between House Prices and School Quality"
Ian Davidoff (Harvard) & Andrew Leigh (ANU)
http://econrsss.anu.edu.au/~aleigh/pdf/SchoolQualityHousePrices.pdf"Since houses in better school zones are more expensive high-quality public education is not costless. The price of buying into a good school zone may prevent poor families from accessing the public schools of their choice. Given that education can transform the social and economic opportunities of the underprivileged, such social exclusion may perpetuate cycles of disadvantage if left unaddressed."
Say you have two kids one X and Y and you had to pick 1. X lives within the school catchment zone, but Y doesn't. Y has a greater academic merit than X. How do you pick? I'd say the school should pick Y. Location shouldn't come into it. You don't deny a meritorious student a place at university because he doesn't live within a 2 km radius and accept the less meritorious student who does live within a 2 km. Neither should you do it anywhere else.
Just think how you would feel, if you were denied a place at university, not because your marks weren't good enough, but because you didn't live close enough. Is that fair?
