Like others our GCs asked the parent’s for brag sheets, talked to the kids and also got two teacher recommendations junior year that were not necessarily the same as the ones writing the official recommendations senior year. I don’t know how much they used from the brag sheet, but I think it helped them put the kid in context. I mentioned for my younger son that he dropped his 504 plan coming into high school, but that the lack of using extra time probably affected a few of his grades for the worse. Most teachers didn’t ask for extra info. The exception was the APUSH teacher, a lot of his questions were about what you did or did not like about his class. What your probable major was, why you’d chosen the colleges you had. He also asked for a photocopy of one of the papers you wrote in his class. It was pretty clear he wanted to be able to say specific things about how you tackled his class and how it fit in context of you as an applicant.
