For the first time, Isidore stepped onto the national stage of the Global English Language Olympiad of Southeast Asia (GELOSEA), a prestigious international academic competition that brings together learners from across the country to showcase their mastery of the English language.

GELOSEA focuses on developing excellence in grammar, vocabulary, spelling, reading comprehension, and critical thinking.

On November 8, 2025, Ada Jiahnna B. Sacdalan, Ziv Marcus M. Delos Reyes, Dannel Jacob G. Vialu, and Chloe J. Gaspar competed in the National Round, and all four secured medal awards, earning their well-deserved spots in the International Round in Singapore, where they will proudly represent the Philippines alongside top English achievers from various Southeast Asian countries.

Their victory also reflects the unwavering support of the school administration, the heartfelt encouragement of their parents and family, and the expert guidance of their coach, Teacher Brenelli S. Francisco, who supported them every step of the way.

As the team prepares for the next stage in Singapore, the entire Isidore community stands united in cheering them on.

Congratulations, Ada, Ziv, Dannel, and Chloe!
