Iucounu, IMO, it will get better. Elementary schools are poorly equipped to differentiate math, especially in early grades. When our DS was 6, he wasn't getting any appropriate math, but it's steadily improved as they got to know him and understand that his needs were real. We have seen that through later elementary it became clearer to school personnel what DS9 needs. (Our 3rd-4th-5th grade track record shows a steady increase in appropriate placement, not all the way to his max capacity, but acceptable to us).

Once you're in middle school, it is so much easier, because the kids are typically traveling between classes; it's less of a big deal to place a kid some years ahead. A scheduling hiccup rather than a nightmare. And once you're in the range of things like EXPLORE testing, or Math League, it's easier to provide them evidence of what your kid can do.

Good for you for advocating for your DS.
