Hi hkc - i briefly talked with some folks with the MNVA (the district in MN that uses K12 curriculum) last year about how it works with HG kids. I think you first do an assessment and your child starts at his/her readiness level, and then no matter how quickly they finish a course, they move to the next level. I believe the kids take the state tests according to designated grade, but the curriculum moves at the child's pace.

Since it's free in MN, it can't hurt to call them. MN virtual academy I think there was some discussion on the MCGT yahoo group about this too.
