Iloilo National High School (INHS) in Iloilo City officially opened its doors for School Year 2026–2027, welcoming thousands of students during the first flag ceremony. This event coincided with the nationwide opening of public schools, where around 26 million learners returned to classrooms across the Philippines. In preparation for this significant day, INHS administrators, teachers, and parent volunteers participated in the 'Brigada Eskwela' program, dedicating weeks to clean and organize classrooms and learning materials for the influx of junior and senior high school students. This academic year marks the full implementation of the Department of Education's new three-term academic calendar, which replaces the traditional four-quarter grading system. The revised schedule aims to enhance instructional time, allowing for longer, uninterrupted periods of learning, and is part of broader efforts to strengthen learning recovery in the wake of disruptions. As one of the largest public secondary schools in the region, INHS is adapting to this new structure to improve teaching delivery and student performance, aligning with the department's goals for educational reform.
