Is that the ITBS? DD has a "SS" number on her ITBS results. I have never had any idea what that means, although I am guessing "standard score."

We did not have any "grade equivalent" information on our results.

Perhaps there is a chart somewhere that explains this? Does anyone have a link?

I think you CAN give the Iowa test out-of-level to get a better idea idea of how a student is performing. I do not think typical grade-level administration of the ITBS tells much beyond how a student is performing for a given grade, though.
