I agree with Sheri on the preschool issue.
As far as Kindergarten, I would not skip it. Kindergarten and first grade are very different. Of course it does depend on each child, I'm just talking in general. A lot of times a child will be advanced academically, but maturely, they're just like other kids their age. So it wouldn't be a good idea to make them skip a grade. You would also have a hard time convincing the school to allow that.
Once she gets to Kindergarten, there are other options. I used to teach elementary school and every single year the levels ranged from kids with learning disabilities to gifted. So when it comes to the basics (math, reading, writing), I worked in small groups. So if the teacher does that, which she most likely will, your daughter would be placed in the more advanced group where the teacher can work at their level.
If your daughter were that far above the rest of the class, there are other options there too. When I was teaching, I sometimes had kids come to my room from a grade lower. They usually joined my class for reading. I also worked in small groups (3rd grade) and had second graders come to my room and were placed in my advanced group. So they can be challenged that way.
If you think she's that advanced, she might even be tested for gifted later on. I'm not sure what the earliest age they can test at, I taught the upper grades. I "think" they can be tested at age 5. In the public schools, that can sometimes take awhile. I had a few parents that turned to private testing to get it done quickly. That would be a company outside of the school system and it would come out of your pocket. I've referred children at the beginning of the school year and it was the end of the school year before they were finally tested. If you can't find anybody in your area, you can call the guidance counselor at your closest elementary school. They can give you advice on how it's being done now and can even recommend somebody to do it if you don't want to wait on the schools.
