I think they all get the same number of questions...I read that somewhere, and if I find the link, I will post.
The primary version is typically for K-1, but some schools also give it in 2nd. It may or may not appear on your report. The school should know, though.
I don't think the score is supposed to be lower the first time they take the test. The first time DS took the test, however, his MPG math score was much lower than it was the 2nd, and 3rd time. IMO, this was NOT as a result of extreme growth - the 2nd test administration looked more on par with what I think is his "true score" if this makes any sense. In reading, I did not see such a dramatic difference. I think that giving reading MPG to kiddos who have been reading for years is kind of silly.
