A friend of mine became catholic when she married her husband, then they split up. She hadnt been religious beforehand, but now she's chosen to go to church every week for the last year in order to get her ds into the local catholic school. She's told me that she doesn't believe in all that 'mumbo jumbo' but the church school gets the best results locally. I understand that everyone wants the best for their children, but this seems a bit disingenuous.
I suppose it's open to all - if you're willing to fake religion you can get into the best school, I suspect that the good results are due to parental influence as you have to be very keen to commit to two years of Sundays at church, presumably this filters out parents who don't care about education, whereas the secular schools cater to all.
I'm not against faith schools or the system, if it gets great results then why not I suppose? Aibu to think faking religion is not ethical though?
