Almost every Filipino student meets the science investigatory project at some point. Far fewer find out that it is the entry point to a national competition structure with a documented ladder.
What is the science investigatory project?
A student research project following the scientific method, prepared for entry into a science fair. In the Philippine system it functions as the unit of competition: it is what a learner enters at school level, and what carries them upward if it advances.
That framing changes how the project is best approached. It is not only a class requirement to be completed and forgotten. It is the artefact that would be judged at four successive levels if it went the distance.
How does the ladder work?
School level, then division, then regional, then national.
At the top sits the National Science and Technology Fair, usually abbreviated NSTF, run by the Department of Education. Below it, regional science and technology fairs select the finalists who form each region's national delegation. Below those, division science and technology fairs feed the regional level, and school-level fairs feed the division.
Regional delegations are capped. Reported guidelines allow a maximum of around 20 official participants per region, comprising the top regional finalists across the categories together with their advisers. The cap is why a division-level win is genuinely competitive: the funnel narrows sharply above it.
What are the categories?
Entries are commonly grouped into life science, physical science and mathematics, with separate elementary and secondary divisions, and further distinctions in some years between individual and team entries.
The exact list is set annually rather than fixed. A category structure you find from three years ago may not match the current one, which matters if a learner is choosing a topic to fit a category.
Where do the rules actually come from?
This is the part worth understanding, because it explains why the guidelines are hard to pin down.
The science fair is run through annual memoranda, not a single standing order. DepEd Memorandum 016, s. 2025 covered the National Science and Technology Fair for School Year 2024-2025, and an equivalent memorandum is issued each school year. Regional offices issue their own memoranda naming venues, finalists and delegations, and division offices issue theirs for the division fair.
The detailed mechanics — judging criteria, exhibit requirements, submission deadlines, registration — sit in the fair's handbook and in the year's regional and division guidelines rather than in a national order that stays put.
The practical consequence: the rules that bind a particular learner are the ones their division issued this year. This is the same pattern that governs intramurals, where the mandate is national and the operational detail is divisional. Our guide on how to find and read DepEd orders covers going to the current issuance.
When do the fairs happen?
Division and regional fairs generally run in the earlier part of the school year, with regional fairs commonly held across the September to December window to select finalists, and the national fair following later in the school year.
Under the three-term calendar introduced by DepEd Order No. 009, s. 2026, activity scheduling is constrained by the term structure, so the windows may shift. For SY 2026-2027 the terms and breaks are in our school calendar guide.
How is this different from the Festival of Talents?
They are separate ladders that share a shape. The science and technology fair handles research projects. The Festival of Talents is a different umbrella covering contests in other areas, running its own division and national levels.
Both use the school, division, regional and national structure, which is why families conflate them. A learner can be on both ladders in the same year for different things.
For a student choosing a project
- Check this year's categories before choosing a topic. They are set annually, not permanently.
- Get the division's guidelines, not a generic template. Judging criteria and exhibit requirements come from your division and region.
- Ask your adviser which level the school is entering. Some schools hold an internal fair and advance nothing; others enter the division fair as a matter of course.
- Build for the exhibit, not only the paper. At division level and above the project is judged as a display as well as a piece of research.
- Note the delegation cap. Advancing past regional means being among a small number for the whole region, so a strong division showing is the realistic near-term goal.
