Based on my research the term “ALDC” refers to “recruited Athletes, Legacies, those on the Dean’s interest list, and Children of faculty and staff.”

Amused by "based on my research" being "I read the linked abstract". Not hating, just amused at what appears to be a euphemistic response.

Sorry, the original title of the post used the word "Staff" so I suppose I was primed for "ALD - Staff" and missed "ALD - [Children of] Staff"

From the introduction of the paper: "... recruited athletes, legacies, those on the dean’s interest list, and children of faculty and staff (ALDCs)."

Children of the faculty.

Children of the faculty
