Or any other tests that would be good for testing math at age 10? thanks!

I can't comment on your ds's ability at all, but I really urge you not to think that an achievement test offers a good indication of grade level. Explore would likely have been the closest because it's more questions at a given grade (all 8th), so you can get a sense from that grade at least. It's much more like end-of-grade type testing than a regular achievement test. For the other tests, I have a child who tested on the WIAT in 1st with grade equivalents of 8th grade. For the WJ, taken in 4th grade, the GE were almost all >18.0. There's no way the school would take those seriously, nor should they!

AoPS provides a great supplement either doing the classes online or just playing with alcumus and reading the books.
