At least five topics are relevant to the professional development of school principals in Australia. First, the Deputy Principalship might well be considered an internship for guided experience in the skills of administration and in the art of leadership. Second, although programs of study in administration vary from institution to institution, a typical one involves scholarly pursuit of knowledge and also emphasizes the value of experience in enhancing the relationship between theory and practice. Third, regional associations of the Australian Council for Educational Administration provide opportunities for professional development, especially in relation to matters of professional knowledge and the professional culture. Fourth, an aspiring school principal can develop his knowledge and skill through travel, research, and by pursuing such specialized secondments as curriculum adviser, professional assistant in a regional office, or member of a research and development group. Fifth, professional development is influenced by such "career development resources" as personal commitment, persistence, visibility, time availability, knowledge, reputation for expertise, and articulateness.
