This study assessed internationalization practices related to cross-border partnerships and educational standards among State Universities and Colleges (SUCs) in Region I, Philippines. It examined five domains of cross-border partnerships and five domains of cross-border educational standards, identified implementation challenges, and formulated a strategic action plan. A descriptive-correlational design was used. Five purposively selected university officials or coordinators directly involved in internationalization initiatives represented the five participating SUCs. Data were gathered through a structured and validated questionnaire and analyzed using frequency count, percentage, weighted mean, and Pearson product-moment correlation coefficient. Results showed a very high level of implementation for cross-border partnerships (overall mean = 4.75) and cross-border educational standards (overall mean = 4.89). Mobility programs and academic partnerships were the strongest areas, while research collaboration and scholarly engagement obtained the lowest partnership-domain mean, although it remained highly implemented (mean = 4.36). The manuscript reported that the overall relationship between cross-border partnerships and educational standards was not statistically significant. However, research collaboration and scholarly engagement, as well as internationalization governance, support systems, and quality assurance, showed significant positive relationships with support systems and institutional capacities for internationalization. Selected institutional-profile variables were also significantly related to specific internationalization dimensions. Implementation and compliance problems were generally assessed as moderately serious. The study concludes that Region I SUCs have substantially institutionalized internationalization, but sustained research collaboration, resource allocation, monitoring, and inclusive internationalization-at-home mechanisms require continued strengthening.
