Is your daughter very outgoing? Many quiet/reserved children will score lower on a one-on-one IQ test than on a group/paper one.
I agree with Dottie that this could be the reason for the discrepancy. I was painfully shy as a child and I have horrid memories of my IQ testing experience. I know for a fact that I was nervous, uncooperative, and generally a wreck. As a result, my parents were told I wasn't gifted. I have no idea what my scores were, but I always did well on the OLSAT and group achievement tests. I was finally identified as gifted in 5th or 6th grade but I'm not sure what they used.
I agree with Dottie that if it's an advantage to have her identified, then seek out a tester who would be a good match for her.
