Inside DepEd’s Trimester Plan for School Year 2026–2027

DepEd first presented the trimester system as a proposal in February 2026. At that point, the department said no final decision had yet been made and that consultations were still ongoing. DepEd described the reform as part of a broader effort to simplify planning, improve use of academic time, and reduce teachers’ workload.

By March 19, 2026, the reform moved beyond the proposal stage. Search results from the Department of Economy, Planning, and Development’s official post indicate that President Ferdinand R. Marcos Jr., chairing the DEPDev council, approved implementation starting School Year 2026–2027. A matching media report from Manila Standard described this as approval of a three-term school calendar to counter learning disruptions.

What “trimester” means in practice

The basic structure is this: the school year stays roughly on a June to March cycle, but instead of the usual four grading periods/quarters, it is reorganized into three academic terms. Under the framework reported by DepEd and major media, the terms are:

• First term: June to September
• Second term: September to December
• Third term: January to late March

DepEd’s framework keeps the school year at 201 school days, but redistributes those days across the three terms. Each term is supposed to have around 54 to 61 instructional days, with fewer interruptions from non-academic events.

Why DepEd wants the shift

DepEd’s stated rationale is not simply “fewer report cards.” The department says the goal is to create longer, more continuous teaching blocks, improve lesson pacing, and lower the administrative burden on teachers. Education Secretary Sonny Angara said the intent is to safeguard education quality by reducing fragmentation in the school year.

A major policy driver is the repeated loss of class time from typhoons, extreme heat, local suspensions, celebrations, contests, and school paperwork. EDCOM 2 said that in SY 2023–2024, around 53 teaching days were lost, roughly equivalent to losing a full quarter, and that more than 115 mandated celebrations and activities can further cut classroom instruction depending on local practice.

How the new calendar is supposed to work

DepEd’s proposed framework has three types of blocks:

1. Instructional block
This is the main teaching period in each term. It is intended to protect sustained classroom instruction and reduce interruptions from assemblies and non-academic activities.

2. Enrichment block
This is where remediation, enrichment work, grade computation, checking school forms, planning, and wellness breaks are meant to happen. In other words, DepEd is trying to move many teacher-heavy and catch-up tasks out of the core teaching flow.

3. Opening block
This appears to apply to Term 1 only and is intended for opening-of-school-year requirements and startup activities.

What happens to grading

The practical implication is that schools would move from four grading periods to three grading periods. The academic year would still end with assessment and recognition processes, but the reporting structure becomes term-based instead of quarter-based. That is the core operational meaning of the “3-grading period system” in the approval announcement you shared.

One important caveat: I did not find a final, publicly posted DepEd implementing guideline yet that spells out the exact revised rules for classroom assessment, card issuance, ranking, honors, or promotion under the newly approved system. What is public so far shows the framework and the approval direction, but not the full final operating manual.

What DepEd says will change inside the classroom

DepEd is also pushing “low-disruption alternatives.” That means celebrations and observances would, as much as possible, be integrated into lessons and outputs instead of requiring separate half-day or whole-day school programs that interrupt classes. DepEd gave examples such as embedding national or cultural observances into reading materials, writing tasks, science discussions, and project-based learning.

So the reform is not only about changing the calendar. It is also about changing how schools handle events, so instructional time is protected even when schools still observe important national or local occasions.
