I feel bad that no one responded to you! But, also… I think you got no response because the question is so broad.
I would probably start by just looking to understand what it means to be gifted. There’s a book called “a parent’s guide to gifted children” by amend/kirchner-morris.
If your child was identified at school, keep in mind that the school programs are often a combination gifted/talented. And the testing reflects identifying both. So, a child may be talented (high achievement) in a subject but not really fit the gifted ID.
Then, I would just parent and observe your kid… help them follow their interests. If you run into any issues, keep in mind that your kid is always gifted and see if you can find any info in the gifted resources about that issue (perfectionism, having trouble making friends, school problems, etc)
Davidson gifted is focused on “profoundly gifted young people”. You can look up “profoundly gifted” for a better understanding of what that means and what issues profoundly gifted young people and their families face.
