"teacher the child may indeed in fact be brilliantly able but the test score is the measure used, and on that measure the AP says the child is so far below an acceptable score that admitting her would breach the school's admissions criteria."
You are extrapolating. They didn't say 'the child is so far below an acceptable score....' they simply said 'accepting her with that score would...' which would be the same as if the score was simply 1 or 2 below the last child admitted.
Of course it would breach the admissions criteria. Bad luck for them that they breached the admissions code by making not one but two errors and that the errors cost Perma's DD a place at the school.
"There really is no denying that a child way outside the acceptable zone is in a different position to a child who has a longer bus journey to school or a longer walk that its peers."
Absolutely correct. Totally different position. Fortunately for Perma, this case is not about prejudice, it is about maladministration, which puts her DD in exactly the same position as any other child affected by maladministration.
"The EFA is therefore highly unlikely to order a fresh appeal. That really is the bottom line, in reality."
The EFA is a relatively new body. If it follows LGO lines, then it should order a new appeal, or even recommend that the place is reinstated to expedite justice. I don't think anyone can say what it will do or is 'highly likely to do'.
"The BV ruling is indicative of the LGOs thinking on this. It's useful and it makes sense."
The BV ruling is irrelevant because that school had a pass mark, this school didn't.
"And lougle yes I do get the difference between a pass mark and rank order and don't consider it material, because it isn't."
Of course it isn't, in the world of Yellowtip, where the admissions code, admissions appeals code and several LGO cases can all be dismissed because it 'isn't fair'
