Deadline for appealing is Monday. I hoped to know I’d be high on the waiting list before then but they aren’t releasing positions until after the appeal deadline.
I will not appeal on grounds of the school I want being able to offer anything that the school I’ve been allocated doesn’t as my dc (who is fabulous of course!) is not exceptional in anything which is only in the desired school. The only thing I can see is triple science and despite me being a science teacher they show no particular interest in it. 
The only grounds I can see are related to how positions have been allocated due to circumstance beyond our/the council’s control.
There is a new school. The DFE funding was not signed off on 1st March but has just been signed off this week. Some children who wanted the new school were allocated our preferred school as well as a back up until the new school was funding signed off. This is because they live closer than we do. I know of at least 5 and there are probably more. These back up places have now been removed from the children wanting the new school and will be allocated to people off the waiting list. I am hopeful we will get one as we missed out by 0.06 miles (less than 10m) on 1st March.
My reason to appeal would be if we now don’t get a place because other children not in the first round of allocations have now decided to apply for the waiting list and are higher than us. I assume (but can’t know for definite) that had the new school been signed off that we would have been allocated one at the preferred school and now if we didn’t because of the waiting list with new applicants on it who are higher up the priority we would have been disadvantaged by the organisation of the DFE.
Im hoping I don’t need to appeal due to our likely high place on the waiting list but should I put something in just in case we are in this situation when places are reallocated after the appeals deadline?
