We managed to do this for DS back in grade 2. In the spring I went in to request that for the next year they would put DS with the teacher that would best be able to differentiate and since I knew how much work it would be I asked if it would be possible to also put X who was also gifted in the same class so that they wouldn't have to have two teachers differentiating for gifted kids. The school happily did it (although in our case it was only 2 kids and we were coming off a DISASTER of a year so they kind of knew they had to do something for DS). The actual differentiation was pathetic in the end but at least he had a buddy.
