THIS IS NOT A TRIMESTER AND THE CALENDAR ITSELF DOES NOT CHANGE THE CURRICULUM

The words “three-term” can make this sound like students are moving to a college-style trimester system.

That is not what DepEd is doing.

The calendar change itself does not replace the curriculum.

There are separate curriculum changes happening in Philippine schools, including the Strengthened Senior High School program. Those should not be confused with the three-term calendar.

The major change here is how the school year is divided.

Under the new calendar, there are three grading periods instead of four.

That means teachers will have longer periods to cover lessons before each major grading period ends.

For parents, this is probably the easiest way to understand it:

Your child is not moving into a college-style trimester system because of this calendar.

DepEd is rearranging the school year so teachers and students can have longer stretches to work through lessons without stopping so often for grading and other requirements.

THE SCHOOL YEAR STILL HAS 201 CLASS DAYS

For School Year 2026–2027, classes in public schools run from June 8, 2026 to April 8, 2027.

There are still 201 class days.

The three terms are arranged this way:

Term 1 runs from June 8 to September 15, with 69 class days.

Term 2 runs from September 16 to December 18, with 65 class days.

Term 3 runs from January 4 to April 8, with 67 class days.

So the big change is not that students suddenly spend far more days in school.

It is how those days are grouped.

The school year is also divided into different kinds of blocks.

At the beginning of the school year, schools have an Opening Block for things such as orientation, checking what students already know and preparing them for the year ahead.

Most of each term is supposed to be an Instructional Block, which is the period meant mainly for teaching.

Then there is an End-of-Term Block for assessments, catching up on lessons, helping students who are struggling and giving teachers time for some planning and professional work.

That structure is supposed to keep normal teaching weeks from being interrupted as often.

THE BIG CHANGE IS HOW DEPED WANTS TO PROTECT TEACHING TIME

This is really the reason behind the reform.

A school calendar can say that students had 200 days of classes.

But that does not mean they received 200 full days of lessons.

Classes can be interrupted by bad weather, school events, testing, teacher paperwork, meetings and other activities.

DepEd has pointed to previous school years when many official school days were affected by interruptions.

That means simply counting how many days schools were technically open does not tell us how much actual teaching happened.

The three-term calendar is supposed to deal with that by setting aside longer periods mainly for instruction.

Testing, remediation and some other activities are supposed to happen at more clearly defined times instead of constantly breaking up the teaching schedule.

The idea makes sense on paper.

If a teacher has a longer uninterrupted stretch to teach a lesson, students have a better chance of following it from beginning to end.

But that will depend on how schools actually use the calendar.

PRIVATE SCHOOLS DO NOT HAVE TO FOLLOW THE SAME THREE-TERM CALENDAR

The new three-term calendar applies to public schools nationwide.

Private schools have more flexibility.

They can continue using their own school calendars as long as they follow the required curriculum and meet the legal requirements for school days.

So we should not say that every school in the Philippines has suddenly moved to the same three-term system.

A student in a public school and a student in a private school may still have different calendars.

Philippine Schools Overseas are also being brought into the three-term system, although DepEd has allowed them some flexibility during the transition because they operate under the rules and conditions of their host countries.

This matters for families with children studying in different kinds of schools.

Their calendars may not always match.

THE REAL TEST IS WHETHER STUDENTS ACTUALLY GET MORE TIME TO LEARN

Changing a calendar cannot solve every problem in Philippine education.

It does not build classrooms.

It does not hire more teachers.

It does not put food on the table of a hungry student.

It does not replace missing books.

And it cannot stop a typhoon from forcing schools to suspend classes.

Those problems still exist even under a better-designed calendar.

Rearranging the calendar also cannot by itself solve classroom shortages or heavy teacher workloads.

DepEd says one reason for the three-term system is to make teachers' work more manageable by separating some assessment, reporting and professional-development work from normal teaching periods.

But that is still a promise.

We will know whether it works only after teachers and students live through the system.

The calendar succeeds if students really get more uninterrupted lessons, struggling learners get better help, and teachers spend less time trying to teach while also handling everything else at once.

If schools simply move the same interruptions into a new calendar, then not much has changed.
