@SculptorDad, You have been given many possible reasons for your daughter’s BS results including my own:

You seem to be taking her results as a failure of your advocacy. The schools were evaluating your daughter, not your ability to promote her. I can’t know exactly how you came across when dealing with the schools or how heavy they deemed your involvement, but if you were perceived to be selling your daughter, packaging her in any way, or telling her story for her, those would not be positives. Apart from a (brief) parent statement indicating your support of your daughter’s choice to attend BS and any questions you might have had about a school’s culture and programs, no more input was required from you. Schools make their decisions based on their evaluation of the student and how that student will fit into, contribute to, and benefit from their programs. Your daughters results were not about you.
With that, I’m afraid I have to stand by my original assessment; your daughter is a wonderfully accomplished young lady, but not a good candidate for most of the traditional boarding schools. I wish her well at Grier next year.
