Wow. So you're saying they never get promoted to their real level?
Ametrine, I tend to take a more holistic approach to these things. I favor keeping gifted kids with age mates for many reasons. One reason being that so many skills are purely developmental. Handwriting is a good example--not just handwriting, but writing. Social maturity. Interests. There is eye stuff, attention skills, executive function.
I do think academic fit is important, too. I think a skip might be a good idea when the need for academic acceleration is clearly greater than the difference in developmental skills compared to their new grade-mates that would be caused by the skip. So if a child with a high IQ is typically developing in all other areas they would be one year immature if skipped. Personally, I would want my child to be operating at least two grade levels ahead academically. I feel like only then would the skip be warranted.
So maybe that is where the "at least two years advanced" comes from. Also, depending on the school, there will be many kids operating comfortably above grade level in their respective grades. Again, depending on the school, a child who tests one year advanced might be in the middle of the pack.
