Some parental advice from all the lovely parentals? Non parentals also welcome :D

There is no known or demonstrable academic advantage to skipping a grade.  There are, however, known and demonstrable disadvantages that range from social issues to the reduced likelihood of things like sports scholarships.  I'd say that you might want to approach the question under the assumption that there is no academic gain to be had, see what it looks like when the metrics are different.

In post 10 I mentioned my personal anecdote about skipping and whatnot.  There might not be across-the-board advantages to skipping per se, but at least in my situation the logistics of our school system were such that, had I not skipped, I would've been in independent study for all of 7th and 8th grade in math and science (as I basically tested out of algebra at the beginning of 6th grade, and had I still been in 5th they would've run out of things for me to do by the start of 7th).  That (being solely in an independent study and not a classroom setting at such a young age for multiple years) might've been academically/socially harmful in itself.  Maybe.

Just stuff to consider.
