In higher education, internationalization is essential because it exposes students to a globalized environment; however, teachers must be sufficiently prepared for this challenge to internationalize. Many studies emphasize the significance of faculty views on and institutional support in relation to institutionalization; however, there is a knowledge gap regarding how perceptions, support, and barriers interact with teachers’ readiness for and obstacles to internationalization, particularly in the Philippine setting. To fill this gap, this descriptive-correlational study used random sampling to examine 200 higher education teachers’ views on and readiness for institutionalization, the institutional support available, and barriers to institutionalization at state universities and colleges in Central Visayas, Philippines. Online surveys were used to collect data, which were then subjected to regression and descriptive analysis. Findings reveal that teachers have positive perceptions, receive ample support, and encounter barriers to internationalization. Based on their attitudes, beliefs, and pedagogical strategies, they were ready to engage in internationalization activities, they were well prepared in terms of professional development, cultural competence, and language proficiency, but only moderately ready to engage in internationalization, because of limited prior experience. Their institutions supported them through dedicated offices responsible for coordinating international efforts; however, they were also challenged by their institutions’ lack of financial resources and limited access to global networks and partnerships. According to the study findings, improving teachers’ preparedness necessitates building institutional support, promoting positive attitudes, and systematically removing obstacles. It is advised that institutional policies are strengthened. Research is required to fully understand these dynamics in various educational situations.
