Community colleges play a vital role in providing access to higher educational opportunities for their communities. College completion rates for community colleges, however, have been historically low and few students graduate within a two-year timeframe. Disaggregating these data also reveals significant equity gaps in these outcomes for many marginalized student groups. In order to improve student success rates, community college teams have increasingly engaged in various efforts to restructure their institutions to better support students, including applying the framework of Guided Pathways to more holistically redesign the way colleges function. Coordinating these efforts at scale, however, can be challenging for institutional leaders. To better understand how leaders create conditions for college communities to engage in large-scale and equity-minded institutional redesign, this research utilized a case study approach to examining a California Community College, which was an early adopter of the Guided Pathways framework, and its leaders. Through analysis of college documents and interviews conducted with diverse leaders, seven themes of "Cultures of Transformation" were identified that essentialized the strategic approach these college leaders used to guide, support, and implement this transformational redesign. The Cultures of Transformation included: Learning and Dialogue, Inquiry, Engagement and Collaboration, Distributed Leadership, Innovation, Partnerships and Advocacy, and Equity. Factors that had impacted momentum of redesign work and opportunities for future redesign efforts were also explored. The findings of this study can be helpful for educational leaders and policymakers who seek to better understand and gain perspective on strategies that promote holistic, largescale, and equity-minded change at institutions and across educational systems.
