Marcos approves trimester system for schools without pilot testingA teacher instructs students as classes open for the new school year at an elementary school in Manila on June 16, 2025. The calendar change is a first for DepEd, which had long implemented the four-quarter system. "While the proposal has not undergone pilot testing, consultations have been conducted with various educational institutions prior to its presentation," the PCO said in its statement. The Alliance of Concerned Teachers criticized the calendar change and questioned whether teachers were adequately consulted prior to the decision. He also told the department to align the three-term setup with the existing semestral system in senior high school.
