Our school uses the Stanford achievement tests each year in addition to the mandatory state testing for NCLB. The principal said they use it for "planning" but I'm not sure what that all entails. Anyway, my son is in 2nd grade but 3rd for math. I've asked if he can take the entire 3rd grade level test for the Stanford, to use as out of level testing to help us plan for his placement/curriculum next year. In spite of grade and subject acceleration, things just still don't seem a great match in terms of school.

Has anyone else used this type of test this way? Or should I look at more private testing to help with school advocacy?
