I'm wondering if there are some brain changes with puberty and what, specifically, they are. I was rather scattered in grade school and underperforming. Then I got to high school and everything kind of clicked and I turned into a straight A student (I was somewhat late developing).

Girls in particular seem very concerned about thier appearance by Jr. High/High school and some EF skills are going to be needed to remember to take showers, fix hair, do makeup, arrange outfits, etc. Maybe that will be the motivation needed, although I cringe that it may end up being the superficial stuff that is the motivation to learn some of these skills. Right now it's difficult to even get DD to take showers or change her clothes so she's not wearing the same clothes 2-3 days in a row.
