From the Harvard lawsuit
Research paper by Arcidiacono examined the admission statistics for the Harvard Class 2014-2019
Overall admission rate: < 5.5%
Overall recruited athlete admission rate: 86%
Of the 4 hooks they looked at: Athlete, Legacy, Donor, and Children of faculty, being a recruited athlete was by far the strongest hook.
According to their analysis, if a hypothetical student has a 10% chance for admission at Harvard, being a legacy increases the chance to 50%,
being a donor or double legacy increases the chance to 70%, being a recruited athlete increases the chance to a "near certainty."
Their conclusion.
"This paper has focused on the substantial preferences ALDC applicants to Harvard receive. The advantages for athletes are especially large, with an average admit rate for recruited athletes of 86%.
This high admit rate occurs despite admitted athletes often being worse on Harvard’s ratings than the (entire) applicant pool itself." |
