I'm pretty sure that HowlerKarma's dd is more gifted than mine and, while I do agree for the most part with what she said above, I wouldn't want it to turn you off to the idea that grade skips can be beneficial. While we, too, have found that the way dd learns still isn't a fit for the way schools are set up, school isn't horrible.

For her it is the difference btwn a kid who spent her school days tutoring the other students even in her weak subjects and who, in the early elementary yrs was depressed to the point that she sat at her desk crying in class to a kid who has needed a differentiated learning plan and for whom some of the classes still are not a great fit but who isn't totally wasting her time at least.
