I dont claim to be a master of this, but hope that this info will go a small way toward helping if you did not get the result you wanted.
If it is still the same this year a letter or email will come to you, simply stating pass or fail.
Then contact the school to get the scores. If your child is not too far off the pass mark, telephone the coucil and make an appointment to see
you childs paper. They will let you see it, but not take it away.
This can be useful, as you can pinpoint all manor of things.
In my particular case, the council worker, Linda, at the kent office pointed out to me that the questions that my son had completed were all correct,
it must have been a time issue, and one more mark on his maths would have been a pass.
With this information, you can,if you wish, appeal to the schools you want.
You may hear that the school you want is oversubscribed, full to the brim.
This was the case for us, but although the school was full we won on appeal.
My Son who has aspergers, was one point short, but I know a freind whos child was eight points short. This child won on the third appeal.
The key point is that the child has a consistent history of good results, perhaps in thier key stage exams. My honest veiw is that excuses wont win through. Things like, my sons pet died the night before the exam, or
he had a cold. These things may be considered, but you cant beat consistent acheivment history, consistent with a pass.
Good luck to you all, but if you dont make it , dont give in yet...
