Another thing to point out as far as cheating the system because "X school I'm in the catchment for is horrible and I don't want my child to go there":
My foster daughter's school, as I've said before, has a drug problem, she got involved with drugs through some of the older kids. She's spent the best part of year 11 getting wasted with her (expelled) BF when she should be in lessons and the school made a bloody halfhearted attempt to deal with it. This is the school she ended up at after missing out on the 'outstanding' school by a couple of metres, in an area where people are known to rent in order to get into the 'outstanding' school and avoid this one. When she got involved with the drugs, the reason many parents tried to avoid this school, she was still living at home with her mum, who was completely disengaged and unsupportive.
I have taught in a number of failing secondaries with such problems, including this one. Trust me, the kids of those on this thread who have/are planning on renting/cheating to avoid these schools are NOT the kids I worry about getting caught up in the drugs. The reason is simple: the parents are engaged enough and concerned enough about their child's wellbeing to support them, to listen to them, and to teach them the difference between right and wrong. The children I DO worry about are the ones like DFD was, the ones whose parents couldn't give a damn how their child is doing at school. I'm not saying it's only ever been the kids from the unsupportive homes who get caught up in anti-social behaviour in and out of school, but in the majority of cases the children of the concerned, engaged parents are not the ones who end up as school drop outs on drugs.
Now I'm absolutely not saying that on that basis, the children from unsupportive homes like my foster daughter, as she was in year 6, should be the ones who get priority for the local outstanding school, and the ones from the supportive homes the ones who get shoved into the failing one. Not at all. But I am saying that if you cheat the system and rent in order to avoid your catchment school because it has a bad reputation, you are potentially sending a child like my foster daughter into an environment of temptation, where she is at a disadvantage simply because she lacks the support network that your child has.
It's a postcode lottery, and I appreciate that. But that's the way it works in this country, it's the law, and anyone who rents/uses a second address/bends the rules because they want the best for their child when it means depriving someone else's child is a criminal in my book and upon being found out should be treated as such.
