Well my local elementary the top 'gifted' program is officially for BOTH (1) and (2). And in reality those with (2) really struggle with it and after having gone through it with my son I don't recommend unless the kid is self motivated. I think it's really designed for the kid who are both (1) & (2) and they have changed the criteria a bit to lean it even more in that way.

I would rather the gifted program was for (2) because those are the students who's needs are not being met by the regular classes. But I have no problem with there being special program for (1). The problem as other people say is they are often thrown together and taught the same way when their needs are different.
