Good thought on the "operating grade level" and thanks for the thoughts above that, too, you all.

Yes, I was basing it on the WJ achievement and also on some experience in dealing with her. THe WJ achievement, for example, had her doing independent 4th grade work in language arts. But, at home, she took the 5th grade benchmark test and passed. So, that told me that in 4 or 5 months (start of next school year), fifth grade reading work might be her level. So, either they need to assess her or I need to at home (we do EPGY math at home, so I have that, too, to help evaluate).

Question: how do I assess science and social studies? Is that really based on IQ and reading?
