1) Holistic criteria also favor the powerful and well-connected, allowing them to bypass the same admission review that everyone else is subjected to. For instance, according to The Washington Post, President John F. Kennedy graduated from The Choate (High) School with an average score of 68 percent, when the school’s passing score was 65 percent, and yet he was admitted to Harvard.
2) Holistic admission criteria were invented by Harvard in the 1920s to limit the number of intellectually accomplished Jewish students that were admitted, which they immediately did. Can a device borne of such malicious intent have transformed itself into a wholly noble instrument?
Two very good points. As the country swings towards holistic admissions, expect more and more pissed off people. It's inherently unfair on many levels.
