This report presents the results from the third biennial Texas OER Landscape Survey, administered in 2023 and commissioned by the Digital Higher Education Consortium of Texas (DigiTex) and the Texas Higher Education Coordinating Board (THECB). The survey aimed to explore the open educational resources (OER) landscape, policies, and practices at 169 higher education institutions, including 11 health-related institutions, across the state. The 2023 Texas OER Landscape Survey revealed an OER landscape marked by institutional commitment, diverse adoption goals, and the instrumental role of OER champions on campus. This report not only highlights areas for improvement but also underscores the necessity of ongoing collaboration and faculty support. The trajectory observed in OER adoption is institutionally driven, placing a growing emphasis on student learning impacts and resource quality alongside financial considerations. As librarians and other key stakeholders play pivotal roles, the landscape unfolds organically, showcasing the self-sufficiency of institutions in advancing OER use and development to reach their goals for student success.
