This study addresses the critical issue of low-income student success at Tri-County Community College (TCCC), with a specific focus on reducing the financial barriers posed by commercial textbooks. Recognizing the disproportionate impact of these costs on low-income students, the study implements an improvement initiative leveraging Open Educational Resources (OER) as a solution. Faculty at TCCC were provided with training and support to integrate OER into their courses, replacing more expensive commercial textbooks. The study employed improvement science methodology to evaluate the effectiveness of this initiative. The primary objective was to assess whether the use of OER could narrow the academic success gap for low-income students. This involved a comprehensive data collection and analysis phase, comparing low-income student success in OER-implementing courses against historical data from previous semesters. The study's findings offer valuable insights into the potential of OER to enhance academic equity, as well as noting common concerns about OER among faculty and students.
