This list excludes terms of acting administrator. Terms of service are shown for the earliest of the dates when the persons were named to the position or when they showed up for the job. The “effective” dates of appointments weren’t always precise but were always after the dates of announcement, and they sometimes were before and sometimes after dates individuals actually began work on the job. Likewise, swearing-in dates were either before or after the start of actual work in the position.
