For your dd, this might work: Contact the school she went to before you moved. I live in an area where there are a lot of military people moving in and out, and sometimes a hs student can finish the requirements for hs graduation in their old school at the new school. She'd end up with a California diploma, but who cares? The Utah credits would just transfer back to CA.
That probably won't work for your ds, but you can always ask.
There was an article in our newspaper yesterday about a girl who graduated from Hs in June and from the local community college in August. She'd been taking classes at the community college, and the CC accepted her AP credits from the HS. I think it said she took about 10 classes at the CC during her junior and senior years.
