Given the advent of new forms of schooling in American education, specifically, integrated social-service schools (ISS), a radical rethinking of traditional leadership models is needed. This paper suggests a new role for K-12 public school leaders--that of the school president. Data were derived from a review of the job descriptions of the presidency in 40 Jesuit college-preparatory high schools nationwide. Findings indicate that a congruence exists between the job descriptions and the emerging needs of public ISS schools. Leaders of ISS schools must perform chief-executive officer (CEO) functions, procure and distribute resources, hold together policy and praxis in a complex structure, communicate effectively to a variety of stakeholders, coordinate a wide range of professionals, and promote external relations. Given the triple task of teaching, research, and service, the university is the most appropriate place in which to explore models of leadership for ISS schools and to prepare prospective and current practitioners for the role.
