Harvard's faculty consists of both tenured professors and "ladder faculty" (associate and assistant professors), and other teaching faculty (professors of practice, lecturers, adjuncts, and visitors). Adjusted to full-time equivalents, the heft of the Faculty of Arts and Sciences becomes apparent. So does the mix -- of regular faculty appointees versus others, often practitioners (compare business and law, for example). These data for the fall of 2003 exclude hospital-based medical-faculty members (who equal those shown, from the "Quad" departments), and 9,000-plus unpaid medical and dental clinical appointees.
