Several Catholic colleges and universities, particularly those run by religious orders of priests (such as the Jesuits) used to employ the term "rector" to refer to the school's chief officer. In many cases, the rector was also the head of the community of priests assigned to the school, so the two posts – head of the university and local superior of the priests – were merged in the role of rector ("See "Ecclesiastical rectors" below"). This practice is mostly no longer followed, as the details of the governance of most of these schools have changed. Creighton University still appoints a rector. At the University of Notre Dame, the title "rector" is used for those in charge of individual residence halls.
