school that said it didn't tolerate bullying and catered for Gifted kids.... it wouldn't take a lot for us to walk but, as you said mm, there is the ART.
Sometimes if there is more than one classroom per grade, the school arranges for the 2 kids to have not classes together. This has been helpful for us.
Other than the Art, how have the academics been?
I get that your son 'loves the school' but does he have school-friends?
If the academics are 'pretty ok' and there are real friends, then it seems like now would be a good time for you to sit down with DS and say, 'Ok, if we are going to let you try and stay for the Art class, and the school isn't going to help with 'child X' let's brainstorm things that you can do so that you don't continue to be the target of child X, and you make a commitment to trying things from that list.
Things that frequently end up on other such lists are -
Martial Arts classes 2x/week
Attempt to schedule 3 weekend playdates/month that involve something besides videogames (Read 'A good friend is hard to find' for more details)
Learn meditation breathing so that when bully attempts to get emotion out of DS, DS is very boring indeed.
Social Skills class.
Notice that I'm not saying that DS 'should' have to handle this without the school's help.
I'm not saying that it's DS's fault that his is being bullied.
I'm certainly not saying that DS is the one with the problem.
I'm not even saying that any of the things on your list will actually make the bullying stop - but I do think that taking an active approach is better than passively waiting for the situation to change. I think that weighing the pros and cons and expecting effort on DS's part is better than the reactive 'I must stay at this school because of Y.'
However, we do not live in a perfect world. The just right school may not be within 1 hour of your home. School admins aren't filled with perfect people. The only thing that we really have some control over is what we ourselves do.
Make sense?
