I would be curious to know how many students at Georgetown have studied the Nichomachean Ethics.I can't say that I know how many students have studied this great work, but at least the Nicomachean Ethics appears on Georgetown's Index to Online Great Books in English Translation that is linked to on its Philosophy Department page.
Having said that, I note that ethics is notably absent from the department's enumerated aims ("In short, the Department aims to equip its students both with technical skills in philosophy--logical, linguistic, exegetical and phenomenological--and with thorough knowledge of the great traditions of Western philosophy--ancient, medieval, modern and contemporary.").
