A faculty member, regardless of his or her percentage of appointment, is normally not permitted to accept or hold a regular faculty or administrative position at another educational institution. This is true regardless of whether the faculty member is on regular duty at Stanford, on sabbatical, or on leave without salary. (While on sabbatical or leave without salary, a faculty member may accept a visiting professor appointment at another educational institution.) If a member of Stanford’s professoriate wishes to accept a regular faculty or administrative position at another educational institution, he or she will normally be required to resign from the Stanford faculty; a leave of absence for such a purpose will normally not be granted. Upon recommendation from the department Chair and Dean of the faculty member’s school, the Provost may (at his or her discretion) approve an exception to this policy under special circumstances. Such exceptions are rare and based upon compelling reasons.
