My D didn't get an invitation to Scholarship Day either, despite acceptances (and money) to Dickinson, Washington & Jefferson, Hobart & William Smith. Her GPA is a 3.6 (out of 4.0) with APs, honors, etc.
I just honestly don't know what they are looking for. She comes from a good private school, is taking a college level course, sang in Symphony Hall/Carnegie Hall, plays lax and is varsity captain. She even interviews well.
All I can think of is her standardized test scores are only mid-range? Pretty funny for a school that is supposed to not count that much on standardized test scores?
I'm disappointed with this outcome. I would have loved to see her there but without some scholarship it may put them out of the running ...
