This document, after presenting a general overview of the many changes in secondary education, focuses on a highly selected number of changes that have particular meaning for school administrators. Some of the ramifications of educational technology are discussed with emphasis on information systems, computer assisted instruction, and data processing in school management. Next, the emerging role of the school administrator as a management specialist rather than an authority figure receives attention along with the related topics of systems analysis, interaction analysis, group organization, and decision making. To demonstrate school programs that are the products of superior educational leadership and planning, unique aspects of programs in a Las Vegas, Nevada, high school, a Hughson, California, high school, and the Niskayuna, New York, Public Schools are presented. Finally, that administrators and educators must broaden their conception of education to cope with the wide range of pressing problems faced by society is emphasized as the school's role in contemporary society is analyzed.
