In recent years there has been a marked increase in leadership programs, witness the proliferation of books on leadership, articles in business publications about leadership, and institutions offering training in leadership. But, until recently, leadership education was not readily available from accredited universities. This paper examines professional leadership education in those universities in the USA. Our purpose was to ascertain the underlying academic foundations of leadership master's degrees and to determine if there was a discernable difference from the foundation of the MBA. We located 15 institutions with leadership master's degrees. Using catalogs, program descriptions of these programs appear to be more influenced by behavioral science/humanities than the foundations of MBA programs.
