Our school's policy required proving the child was 2 grades ahead in order to skip 1 grade... Kind of silly. Good luck!
I actually think that is a good idea when looking at full grade skips and especially in the early years of elementary. There are a lot of bright kids, who aren't really candidates for grade skips long term, who work at least a grade above level in many areas.
For example looking at MAPS norms, say you've got a 1st grader who is performing at the level of a typical 2nd grader in reading and math (50th percentile for 2nd grade at the start of 1st grade). That kid would only be at the 87th percentile as compared to fall 1st graders in math and 89th percentile as compared to fall 1st graders in reading. At the end of the year (spring) performing at the 50th percentile for a 2nd grader would be the same at performing at the 83rd percentile (math) and 81st percentile (reading) in 1st grade. Those are strong scores, but not "grade skip" strong, IMHO.
