The COVID-19 pandemic has significantly impacted higher education, forcing institutions to rapidly transition from traditional face-to-face (F2F) learning to online learning environments. This sudden shift has presented significant challenges for graduate students, faculty, and administrators because of limited training and support for implementing innovative strategies and technologies. These challenges lead to an imbalance in the operational environment, disrupting classroom instruction and creating anxiety from the additional workload supporting complex and uncertain environments. The design for this research project was an instrumental case study focusing on one private University in South Central Texas designated as a Hispanic Serving Institution (HIS). Our population for this case included University graduate students, faculty, and administrators in the school of education from the Summer of 2021 through the Spring of 2022. Data were collected and analyzed using Miles and Huberman’s code-to-theory framework to identify categories, themes, and develop a Comprehensive Institutional Model (CIM) to support the transition to remote and blended modalities in graduate education. This instrumental case study also highlights the need for universities to invest in reliable and up-to-date Information Communication Technology (ICT) platforms, provide accessible training, and develop sustainability strategies and plans. Ultimately, the success of online learning depends on instructional support, instructor presence, and engagement. Universities must work to ensure that all stakeholders are ready for teaching and learning in this new environment.
