So first post on the site but an important question. We have a profoundly gifted son who is in the 99th percentile. He's 10 and doing most subjects at the high school level, especially math. We're homeschooling him since going to school just didn't fit his needs or personality. We would like to explore having him complete high school during his middle school ages and begin working on a degree during his high school aged years. I just have no idea where to start as far as making sure the HS level courses would count for credit. Is it possible for him to work on high school and college at the same time? I'm sure there's lots of you out there who have some knowledge and guidance for something like this. Fire away!

Welcome!

A few ideas:

1) Look at your State's high school graduation requirements. You may find this by reading your State's legislation and/or your State Department of Education website.

2) Look at the websites of several colleges which your child might wish to apply to, and take note of their admission requirements.

3) Here is a post on a recent thread, the second half of which lists some resources which may be of interest.

4) The Davidson Database has helpful articles including Thoughts About College Admission and Writing Transcripts, by Wes Beach.

5) These books by Elizabeth Wissner Gross were written a decade ago however much of the information still applies:
What High Schools Don't Tell You and Other Parents Don't Want You to Know,
What Colleges Don't Tell You, and Other Parents Don't Want You to Know.
These books provide tips and ideas on what to do during the middle school years and high school years to help your child find and pursue opportunities in his/her areas of strength.

6) Because you mention that your child is profoundly gifted and in the 99th percentile, have you considered applying for him to become part of the Davidson Young Scholars (DYS) program?

7) In the event that your username is a real, identifiable name, you may wish to change it to a nickname to protect your child's anonymity, consistent with the forum rules.

Just for background (or consideration if it turns out you really like the idea), you might like to take a look at the early entrance options available at the University of Washington's Robinson Center for Young Scholars: https://robinsoncenter.uw.edu/programs/
They have several levels of programs for differing age ranges and needs. This is a very well-developed early entrance support system, probably the best one in the country. The Transition School in particular is highly competitive, but you never know; if your kid ends up thinking it could be right for him when h for him when he's approaching the age range (7th/8th grade) you can support him in applying.
Definitely check out the Davidson Young Scholars program.
If any of this stuff had been around when I was that age I'd have totally jumped on it, regardless of what my parents might think of the notion. :-)
