Just wanted to share our experience with a recent skip with DD10. Last year she completed 4th grade without any gifted services. We moved to a new district and she was skipped to 6th grade math and language arts. She was in 5th grade gt class for all other subjects, but due to early entrance to K and then many of her gt classmates being "red shirted" she is up to 2 years younger than her classmates. Academically the skip wasn't an issue and her teacher filled any gaps when necessary.
Maturity wise DD gets along better with her classmates than ever before. She used to be bullied, but now has found kids that think like her. Physically some of the girls look much more mature and I suspect this will be a bigger issue next year in middle school than it is now. Some of the girls do stay up later during the week and watch shows that DD is not allowed to watch, which creates a little bit of a gap. But these are issues we talk about all the time with DD and she is fine with being the youngest and has a great attitude about it all.
In mixed aged groups, DD seeks children about 2-3 years older and seems to have a comfortable rapport. So it is only natural that this works well in school as well.
Good luck with your decision. The skip and change was a good fit for DD and I am so glad we took the plunge.
