His school .... are holding an open evening on Tuesday for all parents wishing to appeal. I assume we will get the relevant Bucks appeal packs here
Have just posted something about this in the Bucks section.
You don't NEED to attend an appeal but I would suggest that you do.
Agree absolutely with Guest55. Panels can hear the appeal solely on the basis of the written evidence before them, but they are deprived of the opportunity to ask questions. This could seriously weaken the appellant's chances of success.
