This discussion of changes in administrative roles and responsibilities within institutions of higher education suggests that these roles may change substantially in the first decade of the 21st century as the constituencies of American colleges and universities change. Analysis of a variety of trends in organizational structure suggests that future leaders at institutions of higher education will be more elitist, more career-minded, and more transient. Specific trends suggest that there will be increasing numbers of leaders at such institutions; that these leaders will be increasingly diverse in race, ethnic origin, experience, preparation, and competence; that they will have more specialized skills; that they will be more dependent on professional staff services; that they will follow career paths marked by increased professionalization and more mobility among institutions; and that an elitist notion of leadership will persist despite trends toward participatory decision making. The paper concludes that both change and continuity are essential in all facets of institutional leadership. (Contains 13 references.) (DB)
