Ok, so the standard thing is this:
every school has a set of criteria. They are available on the school website. They tell you what priority is given to different things, a typicla list may be:
- looked after children (fostered/adopted)
- SEN children whose statements specifiy this school
(these first two groups are usually very small)
- siblings of those kids already in school
- nearest child by distance
So that means if you have a sibling but live a long way away, you will get a place ahead of a child who lives close to the school.
Some areas still work on catchment, or on feeder schools. So if you go to x school, you will be given priority over a child who doesn't. If you live in the catchment you get priority over those who don;t even if you house is further away than theirs.
The criteria may be the same across one LEA, or not. Then academies within the same LEA mya have their own criteria.
Different LEA use different things for the residency. You need to check. Ours uses the house where the child benefit is paid to. So your dd's dad could move, and you could get the child benefit paid to his address and then claim his as main residency. As long as he does not have another house it shoudl count (can't let your main residence and rent elsewhere). You need to check what criteria your LEA uses, and also, if the person has to be still living there for the 1st September, when school starts.
As to living in/out of catchment etc. You can phone and ask about last years entry. How many kids out of catchment got in? How far away did they live? That will give you a good idea of if you have a chance.
When you come ot do the actual form, you need to fill it in according to the order you WANT the schools. If you don;'t get first choice, your second choice is considered to become your first, alongside all the others who put it first. It is no disadvantage to you.
if you only put down impossible to get into schools, the LEA will offer you a place at the nearest school which has space (note, not your nearest school) that may be miles away.
