Oh-- and one other thing that I've learned from years of 2e advocacy--
you mentioned a year of academic growth. This is definitely the right idea-- just understand that for all that modern education is aimed at
outcomes-- those are still not guaranteed for any child. What should be present, though, is the
opportunity.
Your child is being deprived of the
opportunity to learn a year's worth of math curriculum. The teacher and school likely do not see this problem because they are looking at a very different outcome than you are-- they see "Xth grade mastery" as the desired outcome, and you see "one year of academic advancement during this school year, starting from September's level of attainment."
Obviously, from the school's perspective, a child that has attained the objective in September frees up classroom resources for those children who haven't. But this does leave such advanced children in a holding pattern-- and that is not a neutral thing, but a negative one. (See "what a child doesn't learn"). Often teachers/schools are slow to realize this unless a child is acting out.
You must be incredibly frustrated that the in-class differentiation that was promised is not materializing at all. I think that a lot of us here can definitely empathize, having been there ourselves. It's maddening.
This is a simple thing, really, to explain-- but requires some finesse not to alienate or cause defensiveness in your classroom teacher. Tread lightly.
