If you haven't already done so, take some time to read through the report, "A Nation Deceived"
http://www.nationdeceived.org/There's an executive summary to get your feet wet (
http://www.accelerationinstitute.org/Nation_Deceived/Executive_Summary.aspx), and then you can plow into the full report for all the gory details.
You should also take some time to read some of the Personal Stories at the Nation Deceived website from students, teachers & parents:
http://www.accelerationinstitute.org/Personal_Stories/Read.aspxThis article might also be of interest, because it addresses some of the concerns of NOT putting your child into an appropriately challenging environment:
What a Child Doesn't Learn
http://www.wku.edu/academy/?p=430Our son skipped K, starting 1st @ age 4y11m. As with your child, the recommendation for skip came from the school... just a couple days before the start of the new school year! At that point, I was extremely ignorant about the world of GT-Ed, and even more clueless about all the potential testing. I'd have to say that reading through the personal stories above helped me the most.
Our son completed a second skip a few months back (at age 8) from 4th into 5th (6th for math) and is doing very well, both academically and socially.
Despite my frequent recommendation of the "Nation Deceived" report, I'll be the first to acknowledge that grade-skipping (single or multiple) isn't for everyone. And, as many have discovered, grade-skipping doesn't always provide a "fix" in and of itself.
But you're off to a good start -- you're asking questions.
