Thanks indigo, yes, I have requested a copy of the IAS through interlibrary loan as my local one does not have it. Not sure if I get hold of one before the meeting. I will try to purchase a used copy as you have suggested.
DS will certainly qualify if they take an objective approach, but do not know what they will come up with, depending on whatever process they have, right now. I asked the principal for forms that I need to fill in, but he says there are no official forms for this process. I am starting to worry.
Also, he says kids who do not progress along with their peers may later turn out unhappy etc..I got scared by that idea, but I am sure DS is pretty social and can fit in with older kids. My brain is just a big mess right now. I am sure IAS can help me figure out most of these elements.
