You cannot use ANY of the reasons that you have just given in your appeal!
a) All schools are treated as equal academically - so you cannot appeal for an Outstanding school because it is Outstanding.
b) Travel problems are yours, not the school's. Parents in your position would be expected to use before or after school childcare to get your children to school on time.
c) You are appealing FOR the school you want, not AGAINST the school you don't want. So special measures, Ofsted report and parking at the other school are irrelevant.
However, on the good side, this is a Year 3 appeal so you basically need to show that the balance of prejudice means they should give your DD a place, because the prejudice to her of not having a place is greater than the prejudice to the school of admitting her.
I am presuming that you are appealing for a place for the last few weeks of year 3? Or is your DD currently in Yr 2 (trickier)?
So, things you need to think about:
- How many children are in the class you would like your DD to enter? (basically, if already well above 30, the prejudice to the school of admitting an extra child becomes greater and greater)
- Have they worked with >30 (or whatever the current in-class number) in other classes, either at present or in the past (so if they have 32 in other classes, but only 30 in this, you can argue that they are well able to cope with an extra child added to the 30)?
- What does the school offer that the offered school does not, that meet your DD's specific needs? (e.g. orchestra; music lessons in a specific interest; coaching in a minority sport that she plays; coding club which your DD has attended before and loves; specific SEN support for her specific SEN)
- How far away from your desired school is your allocated school? How far have you moved? If you have moved a long way, and the allocated school is miles away, you can argue that the desired school will allow settling into the new area much better - this is a weak argument, but can be supported if e.g. your DD has been through a period of trauma such as separation / divorce.
- Size of school (in a very few cases, e.g. specific MH difficulties if supported by a CAMHS or GP letter, it can be possible to argue that a small setting would be better than a larger one)?
Do they have 'upward' sibling priority, so are you high in the waiting list? Or is there only priority for younger siblings?
