Well, I sent an email asking if we could opt out of the math portion of the test or be moved up to the 6+ version and got this response:

"The 2-5 content does go up to 11th grade, so we don’t give the 6+ at the elementary level. Since we use the test as a growth measure for students, I don’t think you can opt out."

Sigh

I also learned that he got 97th%ile on language, but I didn't get the actual score so I'm not sure if that's based on school or national norms. Our current school is relatively high performing, it's ranked like 90th out of about 500 in the state at 76% proficient vs state average of 48%. (Sure beats our old public school; 25% proficient in math, 44% english, the school where they refused to give us a giep and said they had a whole classroom of kids just like ds) Either way 97-99th performance is what we expected in the verbal areas and I do see some value in continuing those tests just so that we can track his growth in his weaker area. Looks like I will have a fight if I want to get him out of the math though and I have to decide if it's worth it. DS is slow on tests and just like the prior times he took the map he took hours per subject and the test overall took much of the past week of instructional time. Not that he gets a whole lot out of instructional time either, but testing can be stressful and certainly puts him in a situation where he is not practicing any social skills or developing in any way.
