A guide for college presidents is presented that reviews briefly the significant research on leadership and power and discusses each presidential constituency. Attention is directed to the uses and limits of the following types of power in many daily situations: coercive, reward, legitimate, expert, and charismatic. Of these types of power, it is suggested that the most effective for the college president is charismatic power, the ability to inspire trust and confidence. When coupled with expert and legitimate power, the combination produces an effective presidency. The president's constituencies include the faculty, staff, students, the influence/benefactor hierarchy, politicians, public figures, the community, bureaucrats, the media, trustees, and alumni. These constituencies are considered in relation to such presidential activities as administration, governance, speaking, and personal relationships. The role of the president and the administration is discussed with attention to structure, delegation, competence, and loyalty. In considering the role of the president and institutional governance, the rationale for faculty and student participation in governance, as well as the importance of the president as the final authority, are considered. A bibliography is appended. (SW)
