It seems like you would use the Iowa Acceleration scale book and advocate for a grade skip and/or subject acceleration the same way that you would as if she hadn't done the work. I'm sure that every school and every state handles this differently. Another thing people seem to do is use the private schools to skip a grade when the public schools say no. I don't know if it would do you any good to homeschool for one year, compacting the two grades, then plan to temporarily re-enroll in the private school the year after to cement the new grade. What about the K-12 online? That's official public school in most states. Are they flexible? I mean, can you compact using the official K-12 virtual school so the new grade is cemented by the public school?
