The Philippine Science High School System is a specialized public high school system in the Philippines that operates as an attached agency of the Philippine Department of Science and Technology. It is considered as the top high school in the Philippines and is viewed to be one of the best in the ASEAN region by 2016.[1]

The PSHS System offers scholarships to Filipino students who are gifted in the sciences and mathematics. Admission to the PSHS is by competitive examination only, and only Filipino citizens are eligible to attend. Graduates of the PSHS are bound by law to major in the pure and applied sciences, mathematics, or engineering upon entering college. The system is known to have a very challenging curriculum which produces the best professionals in the country.

PSHS is known for its active participation in various national and international science, technology, and mathematics competitions such as Sipnayan, Kapnayan, MATHirang MATHibay, Metrobank-MTAP-DepEd Math Challenge, Philippine Mathematics, Physics, and Chemistry Olympiads, Australian Mathematics Competition and Australian Chemistry Quiz. Through private funding, students successfully reap awards in international competitions such as the Taiwan International Science and Engineering Fair, Intel International Science and Engineering Fair, International Math Olympiad, International Junior Science Olympiad and International Physics Olympiad.

A movie has also been released in honor of Philippine Science. Entitled "Pisay", the movie has acclaimed not only national recognition[2] but also international recognition as it was sent to the Toronto International Film Festival. "Pisay" was directed by an alumnus of the school, Auraeus Solito, and was nominated for Best Documentary Feature Film at the 2008 Asia Pacific Screen Awards.

Campuses and system organization[edit]


For 24 years, the PSHS was a single campus located at Agham Road, Diliman, Quezon City where the top 240 examinees in the National Competitive Examination held yearly were accepted as government scholars. All campuses have at most 30 students in each class. However, regional campuses only have three classes in contrast to the main campus which has eight classes per batch. Currently, PSHS has twelve regional campuses in addition to the main campus.

System organization[edit]

The Board of Trustees (BOT) is the highest policy making body of the PSHS System. The Executive Committee (ExeCom), composed of the directors of different PSHS campuses, is a collegial body that recommends policies and guidelines for the consideration of the BOT. The Executive Committee is chaired by the Executive Director, which coordinates the implementation of these policies and guidelines.[6] PSHS campuses are headed by directors who are members of the ExeCom.


The Philippine Science High School was established through Republic Act 3661, authored by Congressman Virgilio Afable, and signed into law in 1963 by President Diosdado Macapagal. This charter mandates the PSHS “to offer on a free scholarship basis a secondary course with emphasis on subjects pertaining to service with the end in view of preparing its students for a science career”. The school started operations in 1964.[7]

National Scientist Dr. Gregorio Velasquez led the PSHS through its first three years. The campus started in a small rented GSIS-owned property along the Quezon Memorial Circle. In 1970 PSHS started building on a 75,000 square metre lot along Agham Road in Diliman, Quezon City.

By the end of the eighties, PSHS started to spread across the nation. The first regional campuses were built, starting with the Mindanao Campus (now Southern Mindanao Campus), located in Davao City, in 1988.

The PSHS System Law (R.A. 8496) was signed by President Fidel V. Ramos in 1997 that established the PSHS System and unified all the existing campuses into a single system of governance and management. Thus, the PSHS continues fulfilling its mandate “to offer, on a free scholarship basis, a secondary course with special emphasis on subjects pertaining to the sciences, with the end view of preparing its students for a science career”.

Academics and admissions[edit]

Admissions process[edit]

Roughly 20,000 students take the Philippine Science High School exams annually. Those who achieve the highest scores are admitted to the PSHS Main Campus, located in Quezon City. They may, however, opt to study in a regional campus; The rest are admitted to campuses in other parts of the Philippines.

Admission to the PSHS System is through the PSHS System National Competitive Examination (PSHS-NCE). The screening consists of tests in Verbal, Abstract Reasoning, Science and Mathematics. To be eligible for admission, applicants must be Filipino students who must belong to the top 10% of the graduating class or must have special aptitude in science and math.

Academic grading system[edit]

The Philippine Science High School uses a grading system similar to the major universities in country. Grading is cumulative, taking two-thirds of the grade earned for the current quarter (i.e. the transmuted grade, such as 1.25) and adding it to a third of the transmuted grade from the previous quarter.

Grade Percentage Range Equivalent Range
1.00 96 - 100 98 - 100
1.25 90 - 95 95 - 97
1.50 84 - 89 92 - 94
1.75 78 - 83 89 - 91
2.00 72 - 77 86 - 88
2.25 66 - 71 83 - 85
2.50 60 - 65 80 - 82
2.75 55 - 59 77 - 79
3.00 50 - 54 74 - 76
4.00 40 - 49 70 - 73
5.00 Below 40 Below 70

Note: The percentage range is used in actual computations while the equivalent range is used to translate grades for external usage.

Director's List[edit]

A student who garners a weighted average of 1.50 or better qualifies on an honor roll known as the Director's List each quarter. Note: The distinction of 1.50 is important as only two decimal places are considered. If the weighted average is actually greater than 1.50, even by just a hundredth, the student does not become part of the list.
