Might be worth checking with your school to see if they have specific rules, too. At DD's school, they have to be two full grade levels advanced in all subjects to be permitted testing for a grade skip, which could still be denied. We're trying to decide about this now, but suspect that, with such stringent criteria, this means that we'll be met with a lot of opposition. So, a rising 1st grader would have to be working on a grade 3 level to be considered for a skip to grade 2. That's not just her school; that's district-wide.
