Welcome, walkingon!
The question you're asking is crucial - how do we get what we need for our DC's (Dear Children)?
If you search previous posts on this board, you'll find that there are multiple ways we parents are trying to find what our kids need. Some will grade-skip or accelerated in certain subjects, some are homeschooled, some are involved in distance education, some do a combo of all of these.

Start with what is available in your current environment - in your town, your school system. From your post, I couldn't figure out what your DD'd explore scores were - do you mean 50th %tile for 8th grade norms, as a 4th grader? If so, those are really good scores. I would share the scores with your school, and see if they can accelerate or grade-skip, or at least supplement your DD's school experience in some way.

We have done distance learning on-line, and this has been a great experience (though expen$ive). Our talent search has Satuday programs that have been terrific. I'm a big believer in learning a musical instrument. DD plays violin, and is quite good for an 11 year old (she made All-State orchestra this year).
We also go to the symphony, museums, travel to historic places, etc. etc. etc. Is it enough? No, but we are doing what we can at this point for DD and DS.... Hope this helps.
