She isn't ready for a grade skip. While she understands math, she hasn't memorized all the addition facts. Her handwriting is still iffy, although improving. However, it would cause problems in 2nd grade.
The biggest thing is that we don't have a piece of paper that says she is HG. The IQ test they did at school when she was four said she was barely above average in intelligence - and they discounted the high vocabulary as just being a younger sibling.
I can easily see her skipping 2nd, but she just isn't ready to move into 2nd now - not that they would let her.
