Following a major statewide developmental education reform in Florida, we explored institutional transformation among Florida College System institutions. We used statewide survey data to examine lead administrators' perceptions of challenges encountered during the planning process, ways in which colleges engaged in sensemaking (i.e., social processes for developing shared understanding) and organizational learning, and perceptions of the institutional transformation processes and outcomes following the reform. We found that institutions engaged in numerous types of sensemaking and organizational learning practices to promote change. Yet, despite different approaches taken to institutional transformation, almost all respondents reported that the change process was highly collaborative and involved a broad range of stakeholders. Keywords Developmental education. Community colleges. Institutional transformation Community colleges across the nation face increasingly complex internal and external environments, resulting in an increased emphasis on the need for change (Bess and Dee 2012). One area of focus for change is developmental education, given that 68% of students attending twoyear institutions must take developmental (or remedial) courses and that only 28% of these students graduate within eight years (Community College Research Center 2014). Studies have shown that developmental education may have negative impacts on students including delaying time to gateway course completion (Scott-Clayton and Rodriguez 2015) and reducing credit accumulation (Martorell and McFarlin Jr 2011). In a meta-analysis of developmental education studies using quasi-experimental methods, Valentine et al. (2017) found that students assigned to developmental education who were just below college-ready performed significantly worse on the likelihood of degree completion, credit accumulation, and passing college-level courses relative to similar students who were not assigned to developmental education. Additionally, developmental education can impact students negatively through increased costs and debt related to courses that do not provide college credit. Annually up to $7 billion is spent on developmental education expenditures nationwide by students and institutions (Scott-Clayton et al. 2014). In Florida developmental education costs were estimated at $154 million annually, with students paying $73 million through tuition (Underhill 2013).
