DS has Wonder Woman for a teacher and somehow she manages to give him work at the right level. She seems to put in a ton of hours doing prep work that other teachers do not necessarily do. And since the school has a very open layout, I think she gets the help of paras, at times. She also uses the computer with DS....for instance puts him on the computer when she is teaching to the 60 percent so that he doesn't have to sit through that. Not an ideal situation, and it would be better for him to be in a class learning with kids of similar ability (i.e. a higher grade for math), but there are all kinds of logistical problems with that as well, for instance the class schedules not matching up.
I am grateful that our district has a magnet for highly gifted upper elementary kids, but it only has room for about 25-30 kids per grade (coming from many elementary schools all over the district), and so few kids qualify. My fear is that at some point someone is going to decide that this is no longer "politically correct" and scatter the kids back into the neighborhood schools. Teachers/principals are already griping & making noise about how they lose the best scoring kids to the magnet, dropping the averages for their schools.
