Ok, I shall try to keep this brief.
DD (7) goes to a school outside of the village in a rural area so children who live in the village take priority. We missed out on a place for DS by .6 of a mile, he was first on the refusal list as a cat D pupil. Only one other cat.D didn't get in.
3 other cat D pupils did. 2 children have moved to the village since and have moved DS from 1st on the waiting list to 3rd 
DD is a v shy child and we would have to move her if DS doesn't get a place as I work away and DH can't be in two places at once, DS also attends the pre-school attached to the school but as I am told this is a human element and doesn't count.
We have learnt that one family rented a house in the village and have a place (no siblings) but have since moved out of the village, I stress that we need concrete evidence of this, but does it make a difference? We are also aware of another family where the parents have split and the children are only based in the village every other w/e, again, not sure if this makes a difference?
Our appeal is on Thursday, we are not holding our breath as it feels as though an appeal is our right, but in practice is absolutely pointless as they will say no anyway.
One of the TAs at the school has told us that in the past they have sent 5 of the brightest pupils on a year for the equivalent of one fulltime child's placement (say 30 hours) and this has been allowed by the LA and 31 pupils have been allowed to attended. Anyone know if we can suggest this?
Does anyone know of anyone who has actually won an infant class size appeal? We are really beating ourselves up atm as we would never have sent DD to a school we would have to move her from.
Sorry for the waffly post, I feel like a deer in headlights.
