The IAS addresses whole grade acceleration, and all the myriad factors that can contribute to success or failure in that. It does not address single-subject acceleration, because that does not represent an immersion into a new group, and all of the dynamics that involves. Being the youngest kid for one hour a day is obviously not the same as being the youngest for seven hours a day.
It seems to me that when the school says, "The same standards apply," the first thing they should be doing is telling you how they define those standards. They may not be using the IAS at all.
