Trimester, or trial run?

By Herman M. Lagon

The announcement about a possible trimester system in basic education sounded familiar to some of us, almost like hearing a song we have been playing on loop for years. In very few private schools, the idea is hardly new. At Ateneo de Iloilo, for instance, the K–10 program has lived with a trimestral rhythm for nearly a decade. The school calendar there moves in three steady arcs: an opening surge, a midyear stretch, and a final push toward March or April. It is not perfect, but it is not alien either. Yet the present national conversation feels less about the calendar itself and more about the old tension between policy imagination and classroom reality. The question is not whether a trimester can work. It clearly can. The question is whether a trimester imposed from the center, without the slow work of listening, adapting, and preparing, will carry the same results.

The difference usually comes from how reforms begin. In schools where the trimester system works, it rarely started as a top-down order. It began with hard, honest questions: How do our students really learn? When do teachers start to burn out? Which subjects need longer, quieter stretches to truly make sense? That question alone opened months of discussion. The conversations did not rush. They unfolded over time, drawing in teachers, parents, counselors, and even the staff who saw the school’s daily rhythm. What grew from those talks was not a strict timetable, but a pace everyone could live with. Studies show reforms work better when they grow from real conditions and teacher capacity (Fullan, 2007; OECD, 2019). Change sticks when the people living it help shape it.

The hesitation heard from many teachers today carries a familiar message: the real issue is not the calendar, but the classroom. The 2022 PISA results placed the Philippines near the bottom in reading, mathematics, and science, with many students still caught in learning poverty (World Bank, 2023). That did not happen because the year has three terms or four quarters. It grows out of crowded rooms, missing textbooks, unstable power, and teachers juggling reports while racing the bell. A public school teacher in Capiz once described her class as “a jeepney at rush hour,” with 50 students sharing 30 chairs. A trimester will not suddenly produce 20 more seats.

Supporters of the proposal are not entirely wrong, though. There is a quiet logic behind the idea. DepEd has pointed out that the current calendar is fragmented by hundreds of mandated observances and reporting requirements, which often interrupt instructional time. A trimester system, on paper, promises longer, uninterrupted learning blocks and scheduled breaks for planning and remediation. Internationally, some systems using trimester or block scheduling report improved focus and deeper learning when properly implemented (Dexter, Tai, & Sadler, 2006). The appeal is understandable. A school year that breathes in three measured cycles sounds healthier than one that constantly sprints.

Still, the concern from the ground is less about the concept and more about the sequence. Teachers worry that a trimester will multiply grading cycles, deadlines, and forms without removing the tasks that already crowd their schedules. Many remember earlier reforms that arrived with glossy presentations but little material support. The spiral progression approach in K–12 aimed to build mastery by revisiting concepts over time. But in practice, teachers often lacked proper training, clear sequences, and enough materials (Orbe & Manalo, 2018). Mother Tongue–Based Multilingual Education and Spiral Progression, though strongly supported by research, also faced setbacks where resources were scarce and implementation was uneven (Walter & Dekker, 2011). Good theories can falter when they land on unprepared ground.

There is also the human side to consider. A trimester shortens the clock. Lessons move quicker, tests arrive earlier, and the time to recover from missed classes becomes tighter. In schools with enough resources, a faster pace might help. But for a child who misses weeks because of floods or sickness, it can feel like time running out. Research shows that faster or extended schedules can improve outcomes, but results vary widely and depend on the quality of support and implementation (Patall, Cooper, & Allen, 2010). Our school year already adjusts to storms, heat, and sudden suspensions. Without stronger support, a quicker cycle may deepen old problems.

Schools that have lived with the trimester system often share the same quiet insight: structure alone does not shape a young person. The calendar is just the bones. The real formation happens in small spaces — homeroom chats, after-class corrections, guidance sessions, and enhancement schedules that help a confused teenager breathe. When the academic rhythm tightens, those spaces shrink.

Across schools, the feeling is less rebellion and more quiet exhaustion. Teachers have ridden through reform after reform, each introduced with big promises. They sit in trainings, rewrite plans, adjust grading systems, and then prepare for the next shift. Studies show that improvement often comes from stability, because teachers can deepen their skills over time (Hargreaves & Fullan, 2012). Too much structural change can sap the energy of those who are supposed to make reform succeed.

A more honest stance might be a modest one. A trimester calendar can work, but only when it grows from real classroom conditions. It needs decent rooms, enough books, teachers free to teach, and communities that understand the rhythm of the change. Without these supports, the shift may simply move months around while deeper issues stay untouched. The learning crisis did not start with the number of terms, and it will not end there. Calendars help, but classrooms matter more. The wiser reform may be to listen before we divide anything at all.
