My daughter was skipped from the middle of kindergarten to the middle of first grade. She was very unhappy in kindergarten and was much happier in first grade. It was a big improvement. However, the problem is that the pace of learning isn't any faster in a higher grade and it wasn't a long term solution. I'm glad she is in the higher grade, but it wasn't enough.

My son goes to first grade for part of he day from kindergarten and that is working well.
