In this article, the author discusses the mechanisms of isomorphism through three examples of organizational actions for diversity, equity, and inclusion (DEI) in doctoral education: (1) eliminating Graduate Record Examination (GRE) requirements; (2) adopting bridge programs; and (3) reforming doctoral qualifying exams. Although these actions were once experiments and innovations, isomorphic forces and their underlying status considerations have encouraged their spread and this spread has made clear the need for thoughtful implementation. The examples here are from doctoral education, but isomorphism offers a framework for understanding reform efforts and innovations throughout higher education. Social comparison within status hierarchies is the heart of isomorphic change, and if it is not managed with care, potentially transformative moves may prove to yield little more than momentary enthusiasm--and may even undermine their original aims by creating new inequalities. The article closes with recommendations for leveraging isomorphic influences while managing social comparison risks by protecting learning, community, assessment, and justice--all within difficult political circumstances.
