I would defnitely have your daughter assessed. I have 3 kids as well, same ages and sex as your children. Oldest was tested at 7 and is MG, but many folks assume he is PG because of his personality -- huge reader, big thinker. My daughter was tested this year (2 years later in school than my oldest) and is HG. No one ever thinks that -- she didn't read early, isn't a huge reader now, would rather play sports, etc. Youngest is in process of being tested now -- according to preliminary screens, he is very gifted in math but may not be overall gifted. But again, people assume he is because he's so math-y and talks about math ALL THE TIME. Incessantly.
I think it can't hurt to have your daughter assessed. I think sometimes we make assumptions based outward personality traits and don't give enough credit to quieter, shy-er kids.
