This study analyzed data from 674 institutions collected through an AACRAO 60 Second Survey to investigate the levels of institutionalization of SEM in U.S. postsecondary institutions. Both Resource Dependency Theory (Pfeffer and Salancik 2003) and Institutional Isomorphism (DiMaggio and Powell 1983) were used to frame the study. The researchers analyzed the data through frequency distributions, Pearson Chi Square, and ANOVA testing. Ultimately, the findings indicate that both strong and normative isomorphic pressures shape the adoption of SEM at a structural level of institutionalization and that modest isomorphic pressures prevail for procedural and incorporation level of institutionalization of SEM.
