Hmmm, I lost my post.
I should have started school at 6.5 instead of 5.5....
If you have a kid who will miss the cut-off AND you think he/she is ready, enroll him/her into the closest university laboratory school. Those schools (at least the one my siblings, my inlaw sibs, and I have encountered in various states) are much more concerned with intellectual ability as opposed to chronological age.
