teachers from primary school have known your child for seven years give high recommendation and in our case appeal panel ..... seemed to make up their minds in ten minutes ......
Unfortunately there is a lack of consistency with primary school recommendations. Some are realistic, some are too harsh, some are too lenient.
There is also the problem that, while schools usually have a good knowledge of the standard of classroom work, they are not so good at judging performance in the 11+.
In my local authority, primary school heads have to state in advance of the 11+ the expected range of marks (the pass mark is 121, and heads are required to say whether the pupil is expected to score 131-141, 121-130, 110-120, etc.). I would guess that their accuracy averages out at around 50%!
At the moment I feel I should take it further
Just a cautionary word: I'm afraid there's no point in taking things further just because you disagree with the panel's decision. The panel needs to have done something wrong, e.g. not following the correct procedures, or failing to consider your evidence. See the Q&As, section D.
It might be worth trying to get hold of the clerk's notes to see among other things whether - in the panel's decision making - there was any mention of the points you regarded as important. (They were entitled to disagree with these points, but not to ignore them.) See:
