We ordered our copy from Barns and Nobles (because we had a gift certificate). It is kind of expensive. If your library has it (or available through inter-library loan), definitely borrow it first.
For the 3rd edition, there are no blank forms in the IAS manual. However, there are three examples with forms filled out for each example. We made a copy of one example, white-out the responses, and filled in with our information just to see if DD might be a good candidate.
When we spoke with school recently, the district's GT coordinator did bring up the IAS and I do believe our school does have the blank forms if needed.
If all you need is the blank forms, consider asking your school's GT teacher. Personally, I thought reading the whole manual offered a better understanding (not to mentions some great references) of the big picture on grade-acceleration.
Hope this helps,
