Definitely look at the catchment area on the schools website. Were we live all of the Primary Schools are currently over subscribed so if you don't put down your catchment school as first preference you could end up with a place for a school which has places but is 12 miles away and only had places because because nobody wants to send their children there.
Our Primary Schools have never held Open Days either, parents are shown around during the school day. As mentioned by PPs, some now have virtual tours instead.
Definitely ask about things like before and after school care, clubs and what happens if a child doesn't have anyone to play with. Ours had a friendship bench, Y6s put on guided play sessions twice a week for the little ones, and peer counsellors to settle any arguments.
This is incorrect. In England, there is an equal preference system, and you are at no advantage for putting a school as your first preference. Depending on your area, you will be able to state between 3-6 preferences. Each of these is in effect a separate application, and every who applies, regardless of whether it was their first preference, sixth preference or somewhere in between, is ordered in terms of the admission criteria. This will vary by school,so you'll need to check for each one, but is generally along the lines of children in/previously in care, siblings, distance for non-religious schools. The Catholic school will probably prioritise baptised Catholic children before non-baptised, but that's not to say that you won't get a place necessarily- it depends on the school and how popular it is. Some areas have set catchment areas assigned for each school and prioritise children within this, whereas others just work on distance from the school.
Everyone is only offered one school, and so the only time your order of preference matters is if more than one school is able to offer you a place, in which case you will be offered the school that you put highest. If I put a school first and you put it sixth, but you meet the admissions criteria better (e.g. by living nearer), you will be offered the place above me, assuming that you didn't get into any of your higher choices. I don't get put above you because I put it first. Therefore, you should list the schools in your genuine order of preference, always including somewhere at least one school that you can be fairly sure you'll get a place at (usually the nearest school with no religious criteria). If you don't get any of your preferences, you'll be allocated the nearest school with places available after everyone's preferences have been dealt with, which could be miles away, so it's good to include a local school you'll get into even if you're not keen on it.
What most definitely does not happen (though it is a very common misconception) is that they work down the list of people who put a school first and offer places to them, then the people who put it second, etc. It hasn't worked like this for many years now, and the current system is much fairer.
I'm assuming you're talking about applying for reception rather than nursery. As others have said, I don't think I've ever seen nursery attendance as a factor for admission to a primary school- it gives no advantage. OP, you may be better posting in the Primary Education board where posters really know their stuff to ensure that you don't get given incorrect advice.
