Administrator preparation refers to leadership education graduate programs in universities, granting master’s and doctoral degrees in educational administration or educational leadership. These programs usually include completing requirements for state licensure to serve as school principals, superintendents, and other central office administrators. Students’ degree programs include a plethora of courses including educational finance, organizational theory, leadership processes, education law, education policy, instructional management, research methods, program evaluation and data management, systems planning and analysis, and human resource management. The two most prominent professional associations for individuals engaged in administrator preparation and related research efforts are the National Council for Professors of Educational Administration (NCPEA) and the University Council of Professors of Educational Administration. Researchers for NCPEA reveal that more than 370 graduate programs in educational administration include approximately 3,000 professors and nearly all programs offer the master’s degree and courses leading to administrative licensure, many with an online option. The terminal degree—PhD or EdD—is viewed as a necessity for candidates competing for central office jobs or principalships in many school districts. The historical context and evolution of theory within the field has been important in generating research and change in administrator preparation programs. The American Association of School Administrators (AASA) and the Interstate School Leaders Licensure Consortium (ISLLC), now called ISLLC 2008 Leadership Education Policy Standards, are the primary standards in place for administrator preparation programs. This standardization has raised significant criticism within the field, spurring best-practice research and efforts to reform existing programs. “Interdisciplinary” administrator preparation is a newer movement promoted by growing criticism of traditional administrator preparation. These new degree programs blend graduate-level courses in financial, entrepreneurial, and innovation skills in business administration, public administration, and public affairs with courses in departments of educational administration. In addition to new courses, the popularity of online courses and degrees increases each year. This new program content and the new mode of delivery require research to be conducted to compare the quality of credentials awarded online and through the traditional model.
