An ad eundem degree is an academic degree awarded by one university or college to an alumnus of another, in a process often known as incorporation. The recipient of the ad eundem degree is often a faculty member at the institution which awards the degree, e.g. at the University of Cambridge, where incorporation is expressly limited to a person who "has been admitted to a University office or a Headship or a Fellowship (other than an Honorary Fellowship) of a College, or holds a post in the University Press ... or is a Head-elect or designate of a College".[1]
