The professorship is the top rank at the University covered by these Guidelines. Candidates must have the terminal degrees appropriate for their disciplines. Under usual circumstances, candidates must serve at least five years as associate professor, including the year when the promotion will be considered at the University level, before they are eligible for promotion to professor. Candidates must show clear and convincing evidence of high levels of attainment in the criteria appropriate to their work assignments and the missions of their units. Unless the candidates’ assignments are specifically regional, they should demonstrate national or international recognition in their fields and the likelihood of maintaining that stature.
