My kids also waived their rights to see the letters.
We did, however, hear back some verbal information from coaches, Principals and counselors.
Principal about our son (while we were at the Athletic Scholar Awards): “He’s received some really strong, exemplary LOR’s. He should be proud, but you should be prouder.”
Different Principal (4 years earlier) about our eldest daughter: “Wow, I didn’t realize that her biotech internship had her directly working with the PI. They really like her at the UC.”
Counselor re middle daughter: ~“You have a great and kind daughter! The staff knows that they can trust her for anything. She has a number of unsolicited LOR’s from teachers in her college file.”
They didn’t have to say anything and I asked each child if he/she wanted to know what I was told and each said, “no”.
