Dear Very Sad Mum
I understand how distressing this must have been for you. Unfortunately, distance from the school, and the fact that there are already brothers there, would not be relevant at a selection appeal. Nor would the GAT at Swimming, Cricket and Rugby.
B22. Is it a good idea to submit ....... practice SATs papers, as evidence? ......... I don’t think most panels would be happy to interpret SATs marks, and to accept that a “practice” was done under test conditions, without confirmation from the school. The view is likely to be “If the school wishes to comment on current performance or to provide/update KS2 predictions, it should notify us officially”.
There's quite a lot that we don't know about your case, which makes it impossible to say whether it should have succeeded. (What was the other score? Were any other standardised scores, such as a CAT VR, available? Was the headteacher's recommendation a "1" or a "2"? What percentage of the head's "1" and "2" recommendations actually qualified? Was the year 5 report very good, with references to high achievement? What exactly was the "misleading information"?)
If you still feel very strongly that an injustice has been done, the only remaining option is to seek a judicial review. That could be expensive and time-consuming, and I'm sorry to say it is not at the moment clear to me why a judge should reach a conclusion any different from that of the ombudsman.
If you wish to answer the questions I've posed above, either on the forum or by PM, I'd be happy to try and give my view of your case. However, the fact that the ombudsman has found no fault in the appeal suggests that it may be wise to move on and focus on the 12+.
