ArabellaBeaumaris - when my three dses reached the transfer to secondary age, their headmaster advised all the parents to take account of their children's preferences when selecting their school.
They are old enough to go to school open days, and to make a judgement on which school they prefer, and it is important that they know you value that judgement.
Obviously the parents also have a big say and do have the last say, but I wouldn't have forced any of mine to go to a school they really didn't want to go to. With ds1 and ds2, it was moot anyway, because they both chose local, selective state grammar schools, which we were happy with. We did ask ds2 to consider going to the same school as ds1, as that would have made things easier for us, but he had good reasons for preferring the other school, so we let him make that choice.
With ds3 it was a bit different - he did have a couple of coaching lessons for the 11+, but had a total meltdown because he couldn't cope with the work, and didn't want to carry on and do the 11+, so we dropped the coaching, and let him put the local non-selective secondary down as his choice of school. Luckily it was a good school, and we felt happy about him going there - had we not felt it was a good school, I think we would have had to veto his choice - but as long as the child's choice is a good one, made for good reasons, it is right for the parents to back them up, I think.
Quint - your poor son, it sounds really difficult for him and you. I would suggest you explain the waiting list position to him, and tell him that, if he goes to the independant school in September (because he does need to go to a school, unless you would be willing to home-ed him), that you will tell the other school that you definitely want to stay on the waiting list for a place, and you will check up regularly with the school to see what movement there has been.
You may well find that, if a place comes up more than half a term into the new school year, a lot of children will have settled well into their current schools and will turn down the place if it is offered, so in practice the waiting list might be quite a bit shorter. There is also the unspoken hope that, once at the school, he will settle in and be happy, and will not want to move. Here's a
for you and a
for him, and I hope that it all works out for you both.
