Yep, if we want to send our son to the Catholic school in our area (a very popular one) we will have to get a signed form to say that he attends our church... which he has know for over a year. We are not Catholic (Church of England) but preference is given to children who attend any Christian church on a regular basis in our area I think... plus, like the others said there are also a certain percentage for non-denominational students. Problem is though.... because this school is so popular I guess some Catholic students will have to miss out so that the non-denominational students can attend.
