I don't think GT kids are necessarily organizationally challenged. DS7 seems to have it pretty well in hand, considering he's only 7. I'm sure some kids are really bad, but I doubt the numbers are any worse than those for the general population. Just my sense from seeing GT kids...
Certainly GT kids are not necessarily organizationally challenged. I have not data, but I do think that at least some, though, do have (or appear to have) significant problems in this are. DS has organizational issues and all his teachers say that he is the last kid into the class and the last one out because he can't remember what he needs and his stuff isn't organized.
But as I watch DS13, I am struck by how much more he has to organize than an ND child. Initially, this was because of his own brain; he was interested in so many more things than other kids--everything that was happening in the classroom was of interest (what was on the board, the books on the shelf, the extra material in the text), so the details of what to take on the bus just never made it onto his radar until he was already on the bus and had time to reflect. Because of his curiosity, he had to organize more material than other kids.
Now, the fact that he is HG forces him to take on more organizational challenge. He goes to more different classes than other kids his age. He signs up for all sorts of extra activities and the teachers give him extra projects. Since his schedule is unique, his teachers can't use the same systems for coaching him that they use with the other kids. So he has more to organanize than other kids and less help getting it organized.
The bottom line for us is that his executive functioning is average, but he has to run a lot more stuff through that part of his brain and sometimes he just can't keep up. This leads to organizational problems. I am sure he isn't the only gifted kid who has this problem.
