Curmudgeon you have misunderstood. I will try to explain it the best I can. Let's say that last year the pupil who lived furthest away from the school and was offered a place on first allocation was living 2.1km away (let's call him Derek). Last year then, people who are on the "edge" are those living 2km and 2.2km away from the school i.e. people living this distance from the school could easily have been offered a place or not offered a place... it just depended on the number of children who were slightly closer to the school than them that applied. People "living on the edge" will never know if they are bound to get a place or not, because it depends entirely on statistics for that years applications i.e. the number of year 6 pupils living between them and the school who applied for a place at the school. So if on the 30th October (the day before the secondary school application forms have to be in) a family of four year 6 children moved in next door to Derek and all applied for a place at the school, Derek would not have got his place because these children are nearer (and yes, it really is down to house-by-house on "the egde"). So just because children on your road go to Charter, does not mean that your child will get a place IF YOU ARE ON THE EDGE OF THE ALLOWABLE DISTANCE. To make things even more unstable and changeable from year to year, the "edge" shifts and no-one can predict where it will be. Again, it depends entirely on statistics... how many year 6 children nearer to the school than you applied. No-one can ever know this in advance, not even the school and only 180 will get a place. The adjudication has found that the school was not measuring the home to school distances correctly for an area of children. The school was adding uo to 700m onto their distances which meant they were "beyond the edge" even though they lived much closer to the school than people offered places (derek). You are confusing this 700m with the "edge". This 700m is not shaved off the edge and therefore shrinking it. It is shaved off an individual's distance measurement, and only those individuals who were in the affected area. So if Derek last year got in and he lived 2.1km away, then this year the edge may stay at 2.1 km even with the adjudication... it just depends on how many people nearer to the school applied. It's a statistical lottery that no-one living on the "edge" of past years' maximum distance can predict. If 170 year 6 children move in opposite the school and apply for a place then yes the edge will shrink dramatically. However, allowing children on the affected estates the right to be fairly measured will in reality have very little effect for most people. It may mean that a couple of children on the "edge" don't get offered a place, but then that was always the case. And, by the way, the amount of year 6 children living on these estates and surrounding roads is pretty small.
