My two cents - and I must admit, first, to being new to this, and second, that it sounds like your DD is at a higher LOG than my kids - but now seems the perfect time to do something about your dd's education, before problems come along and underachievement sets in. I'd consider having your DH read articles about the importance of keeping gifted kids challenged - print them out from Hoagies, etc. Here's one of my favorite quotes:

"When gifted children are not given opportunities to work at their own level and pace, they settle for less than their best. They learn to slide by without stretching themselves. Patterns of underachievement are subtle and cumulative; they become harder to overcome with each year. Students who attain A�s on their papers with no effort are not prepared to take more challenging classes in high school and college. When work is too easy, self-confidence to attempt difficult tasks is steadily eroded. A student who has the potential to win a scholarship to an Ivy League university settles for a B average at a state college."

There are private testers. There is a list of recommended testers at Hoagies. http://www.hoagiesgifted.org/psychologists.htm We went to the Gifted Development Center, which fortunately is local to us.

(and lol about comparing your test scores with your DH's. My DH likes to lord it over me that he scored 1 point, or two-tenths of a percentile, ahead of me on the lsat. Speaking of the importance of gifted ed, DH is a product of gifted ed and I am not. Which one of us do you think got into HLS? It wasn't me - my college grades weren't good enough - I didn't learn how to study, or even to think, until much later. And at the moment I like to blame elementary school for being far too easy smile )
