This article outlines the authors’ ongoing study of diversity, focusing particularly on the AQAL model as a linchpin in an evolving theory of “diversity maturity.” Recognizing the limitations of non-integral approaches to understanding and negotiating diversity dynamics, the authors explain how an integral perspectives come to inform their postconventional understanding. The authors share their preliminary theory of the diversity maturity process in which the integral vision/theory that unites diversity, complexity, and creativity is the dynamic relationship among and between quadrants, levels, lines, states, and types. The article concludes with an agenda for further theoretical and empirical inquiry.
