To sustain world preeminence, 21st century university and college leaders in the United States are redesigning their institutions organizationally and culturally to align with the direction of local and global societies and markets. The New American University enterprise model at Arizona State University has become one of the leading organization and cultural redesigns in United States higher education since its inception in 2002. Yet, sustaining a 21st century model such as this one means every individual in the college or university must understand his or her specific role to further progress the new model forward. Therefore, to advance and sustain a 21st century higher education redesign model at a U.S. college or university, it becomes imperative that every master-level professional who works in the academic/student services field at the institution understand his or her specific role in helping to further progress the new model forward. To this end, there is a need to change the way graduate students in higher education/student affairs masters programs are educated to work in the 21st century institution. This change can prepare new professionals to understand these enterprise models and how to integrate them into their practice in order to meet the needs of the institution, local and global societies and markets. The purpose of this action research study is to highlight one program, the ASU M.Ed. Higher and Postsecondary program, and show how graduates from 2007 - 2011 understand New American University concepts and integrate them into professional practice within higher education. Through use of a quantitative approach, this action research study described how the ASU M.Ed. in Higher and Postsecondary program graduate students' understanding of New American University concepts informs their thinking and practice to lead and respond to changes and challenges facing today's 21st century higher education field.
