I'd agree with the others that I'd wait. I'd also add that test results from age two are unlikely to make a difference once she hits school age. Teachers and administrators may be disinclined to believe scores that are many years old and done when she was so young especially if you don't have more recent data.
And, now I'm going to take this a little off topic to ask AlexsMom a side question about her post.
We considered IQ testing (mostly because the IOWA manual has a mandatory FSIQ component that figures into the decision-making process) - but based on genes and observation, I knew she was at least 1SD up (enough to pass the "dealbreaker" guidelines), and even giving her a 0 or 2 for the IQ component, she had a high enough score for recommending acceleration. An IQ score wouldn't have changed our decision (or had any effect on the school, one way or another), so we didn't test.
It's been 2.5 yrs since dd11 went through the skip process using the IAS, so things may have changed. We did need the IQ scores and the manual at that time stated that you should not consider a skip unless the child was at least
two SDs above the mean not one (unless it was for early admission to K for a child who had just missed the cut-off in which case they were willing to accept 1-2 SDs.) Has that changed? Are they now recommending skipping kids with IQs in the 115 range?
The version of the IAS we used also said that without the IQ data, you couldn't even fill out the form. You could leave out above level testing and put in a zero there, but you could not for IQ.
I do also understand that the newest version of the IAS will take a CogAT in lieu of IQ. Is that the case on the form you are using? I'm not asking any of this b/c I question your decision. I am just curious about the process now a days and I've also seen the success level vary rather significantly locally from kid to kid & they often do skip kids here w/out the ability data. I don't know if this plays into the success from one kid to the next or not, though.
