Sharon I am pretty sure that Grinity may have made a mistake predicting a DYS level GAI for kid#1. I could also be wrong but am guessing it won't be much higher than the FSIQ, as you say neither the VCI or PRI are super high. Kid#2 might not even have a much higher than FSIQ because his VCI is not super high but the WMI is, which will be lifting the FSIQ but won't count in the GAI.

But even without Grinity's years of experience I completely agree with her to do what works now and make changes later if you have to. I agree it's not ideal to have to reverse a skip, but there are a number of ways to do it that can be positive. A child that passionately hates school (and brings their anger home to share with the whole family) or determinedly underperforms may be harder to reverse.
