Just chiming in to support the last two posts--Dottie and Gratified really nailed it.
The tests today simply aren't made for these kids, so they're really being misapplied. It's just that they're all that we have, so we go with them. I have ranted about that in the past. Gratified's "flaky" is just the right word for them, I think!

My dream is that someone will come up with a test specially designed JUST to test the tail of the curve. Wouldn't that be helpful! But right now, we just go with what we have.
And I love this paragraph:
As for BB's ambivalence, I say do test if you can swing it, but keep your open mind and don't force fit the child into the data. Let the data help open doors for the child instead.
So right!
