We lived in a small community when DD grade skipped also. She started the year in kindergarten, but halfway through ended up in grade 1. It also went great for her, although day 1 wasn't so good, day 2 was and she was much much happier because of it. We are now thinking of another grade skip is needed and will be investigating that this summer.
Like you, the teachers and admin at her little school were very supportive and helped us get testing done and had everything in place to help her continue to learn at her own rate, even if it meant subject acceleration with the grade skip the following year, but we then moved and had to start over again in terms of getting school on board.
Good luck!
