The proposal by the Department of Education to shift the basic education calendar from a quarterly system to a trimester format is being framed as a solution to teacher fatigue, disrupted lessons and fragmented learning.

But for many educators and parents, the proposal revives a deeper and more troubling question: why does Philippine education keep changing its structure, yet continue to fall behind?

The planned shift, which would reduce the school year from four grading periods to three longer terms, is still under review and subject to consultations. Education officials say the goal is to give teachers longer uninterrupted teaching time and reduce administrative overload caused by frequent grading cycles.

Critics, however, say the issue goes far beyond how the school year is divided.

From stability to constant adjustment

For decades, Philippine public schools followed a relatively stable system. Before major reforms in the 2010s, students completed elementary and high school within a ten-year basic education cycle, guided by a predictable academic calendar and fewer structural overhauls.

That changed with the introduction of the K to 12 program, curriculum realignments, calendar shifts, and now, another proposed reconfiguration of the school year.

“What we see is not reform, but constant adjustment,” said one public school teacher who asked not to be named. “Every few years, the system changes, but the classroom realities stay the same—or get worse.”

Today’s quarterly system, introduced alongside recent curriculum reforms, was meant to standardize assessment and pacing. Instead, many teachers report that it compressed lessons, multiplied paperwork and reduced time for mastery.

The trimester proposal is now being positioned as a corrective move.

The case for trimesters

Education officials argue that longer instructional blocks could help students focus on lessons without frequent interruptions from exams, breaks or reporting requirements. Fewer grading periods could also mean less paperwork and more time for lesson preparation.

In theory, trimesters allow deeper discussion, project-based learning and better pacing—features often associated with high-performing systems abroad.

But critics say theory has not translated well into practice in the Philippines before.

A familiar pattern of rushed reforms

Education analysts warn that repeated calendar and curriculum changes point to a larger governance issue.

“If the quarterly system was flawed, why was it implemented without enough safeguards?” asked an education researcher from a Manila-based university. “And if trimesters are now the answer, what guarantees do we have that the same mistakes won’t be repeated?”

Teacher groups argue that reforms are often introduced faster than schools can adapt—without enough classrooms, learning materials, or teacher training to support them.

This pattern, they say, raises questions about accountability among policymakers pushing sweeping changes.

Falling behind the region

The concern is sharpened by regional comparisons.

Neighboring countries such as Singapore and Vietnam have shown steady gains in international assessments, built on long-term planning, curriculum stability and strong teacher support systems.

The Philippines, by contrast, has struggled with low learning outcomes, with repeated reforms failing to close gaps in reading, math and science.

Education experts note that successful systems do not rely on frequent structural changes. Instead, they invest in teacher quality, curriculum coherence and consistent policy direction.

“Changing the calendar does not automatically improve learning,” one analyst said. “Without addressing class size, resources and teacher support, it becomes another cosmetic fix.”

A question of leadership

For critics, the trimester proposal highlights a larger issue: whether those shaping education policy fully understand classroom realities.

“The constant revisions suggest decision-makers are experimenting on students,” said a parent leader from Quezon City. “If past reforms didn’t work, accountability should come first—not another overhaul.”

The frustration has fueled a growing belief among educators that some officials pushing reforms are disconnected from schools, raising doubts about whether they deserve the authority they hold.

Call for caution, not haste

Even groups open to exploring a trimester system stress the need for caution.

They are calling on the Department of Education to slow down, release detailed studies, pilot the system properly and weigh long-term consequences before implementing another nationwide change.

“Reform should be evidence-based, not reactive,” said one school administrator. “Students cannot afford another experiment that fails.”

As consultations continue, the debate over trimesters has become more than a discussion about calendars. It is a referendum on how education policy is made—and whether lessons from past missteps are finally being learned.

For many parents and teachers, the message is clear: without deeper study and accountability, changing the schedule may only confirm what years of reforms already suggest—that the system keeps moving, but not forward.
