This study examines the Association of American Universities Undergraduate STEM (science, technology, engineering, and mathematics) initiative and the ability of a national organization and its member institutions to reshape norms about the importance and value of teaching and dedicated efforts to teaching improvement. The study is framed with literature from institutional theory, meso-influence theories from organizational theory, and research on higher education intermediary organizations. Our findings suggest that Association of American Universities' influence was a powerful motivator for institutions to alter deeply ingrained perceptions and behaviors. We organize our findings into three categories of "enactments" based on the vehicles through which an influence behavior is motivated: prioritization, social pressure, and recognition. This study was able to provide concrete descriptions for what influence can look like within national organizations that are organizational field actors.
