Hi tigerlb923--we are reading the IAS book by ourselves hoping to be better prepared when we meet with the school.
Parts of the IAS evaluation does require teachers' input and assessment. It basically has 10 sections of evaluation (such as school history, ability and emotional assessment, etc.). Base on the final score, you can consider your options of skipping vs. not skipping grades, etc. (I have only gotten to chapter 2 right now.)
If you have a good local library, definitely consider checking it out. (Our local library does not have any of the books people have recommended, like this IAS, or books by Dr. Ruf, etc.)

And as far as being "obsessed," you are just doing what you believe is right. After all, kids only experience their childhood once. I was really discouraged when my formal DD's preschool teacher said "just let her be a kid" or "what's the rush." Then, I found out that during "reading time," DD was sent to a corner to read by herself while the teacher taught the others to read. It kind of made me sad (because DD was kind of sad) and decided that we might need to find other ways of schooling. So hanging there.... and it is great that we got this site to talk about these issues.
Happy Thanksgiving to all of you! (No school next week, so not sure how often I will get to check the site.)
