Which area are you in?
We are in Lincolnshire / North Lincolnshire and thier admissions policies are on an 'equal preference' basis. That means that you are treated the same for each school irrespective of which order you put them on your form. So if we don't get choice number one but qualify to choice number 2 we are put into their admission system in exactly the same way as if we had put it first. So, we just genuinely put which one we would most like to go to first and there is no disadvantage to putting a school second.
I do believe that some areas are different, and with more academy schools that act as their own admission authority there may also be differences. I would suggest looking at you local education authority admissions procedure or posting in the forum for the specific area that you live and there will be an expert along to help you very quickly. These things have been looked at inside out by people on here so if you try your area someone will be able to help you.
Thanks for your quick reply. I will look up on local authority websites, but what if the schools are in different area, and I will using the form from my area, which is different as well. Which criteria will apply?
