Regional Science High School Union (RSHS-Union) is a specialized system of public secondary schools in the Philippines, established during the 1994-1995 school year. It is operated and supervised by the Department of Education, with a curriculum heavily focusing on math and science. It remains within the ambit of the Department of Education, unlike the specialized science high school system of national scope, the Philippine Science High School (an attached agency of the Department of Science and Technology).

The RSHS System offers scholarships to Filipino students who are gifted in the sciences and mathematics. Admission to the RSHS is by competitive examination only, and only Filipino citizens are eligible to attend. Graduates of the RSHS are bound by law to major in the pure and applied sciences, mathematics, or engineering upon entering college.

In the past years since its creation, RSHS has developed a worldwide reputation as one of the best high schools in the Philippines, public or private. It attracts an intellectually gifted blend of culturally, ethnically, and economically diverse students. Almost 80% of RSHS graduates go on to four-year colleges; many attend University of the Philippines and other highly selective colleges and universities.

Location of Regional Science High Schools

Regional Science High School Union comprises 17 campuses nationwide. Some had been annexes of public secondary schools, while others ahd been established as specialized science high school prior to establishment of RSHS in 1994.

Below is the a list of RSHS's and their mother school or former name.


There is no unified logo for Regional Science High Schools. Each RSHS has its own logo.

Admission and retention[edit]


Students who belong to the upper 10% of the Grade VI graduating class and who have been recommended by their respective principals are qualified to take the entrance examination.

Selection is done in three stages and is conducted by the school. The first stage is the administration of standardized mental ability and aptitude test. The student applicant must belong to the 40 percent of the first stage of examination in order to advance to the second stage.

The second stage is the proficiency test in Science, English, and Mathematics. The stage qualifier should obtain at least 75 percent proficiency level in order to advance to the last stage of the selection process.

The last stage is the interview of the student and parents conducted by the RSHS screening committee. The interview is scored.


A student should obtain a final average grade of at least 85% in all subjects, in any grading period. If a student fails to meet the latter grade requirement the student will be in probation for a period of one year.

There were plans to increase the cut-off grade in Science, Math, and English subjects from 85% to 88% and the rest of the subjects from 83% to 85% but this was not implemented.


Only students who have maintained the grade requirement set for RSHS are allowed to transfer laterally, that is, from one RSHS to another. Transfer from general high school to the RSHS is not allowed in any curriculum year.



Regional Science High Schools implement a curriculum which is different from Regular High Schools (which uses RBEC curriculum) and Science High Schools other than RSHS (which uses ESEP curriculum) in the Philippines and Philippine Science High School (which implements curriculum prescribed by DOST).

The curriculum consists of four levels, which is two years of general studies, followed by two years of a student-chosen major. Students apply for majors in sophomore year, and take four semesters of major classes throughout junior and senior year.

The schools offer an accelerated curriculum for math, science and information and communications technology and a custom-made curriculum tailored for the school in the areas of the English and Filipino language, social studies, and humanities, with required courses and a wide selection of electives. Students have an opportunity to do independent research, and many compete in the annual Intel Science Fair.

The basic science courses includes earth & environmental sciences, biology, chemistry, and physics. First year students tackles earth & environmental science, and Introduction to Physical Sciences (Physics & Chemistry). Biology, chemistry and physics is introduced during second year. Sophomores tackles the areas of botany, inorganic chemistry, and mechanics. zoology, organic chemistry, and thermodynamics is being studied by juniors. Seniors have human biology, analytical chemistry and electricity, electronics, electromagnetics, and vectors.

In mathematics, students take up elementary mathematics, elementary and intermediate algebra, plane and solid geometry, and probability and statistics during freshman. Linear algebra, analytic geometry, plane and spherical trigonometry, and statistics in research were taken during sophomore. Differential and integral calculus and differential equations, and Advanced Statistics are learned by juniors. Seniors tackles advanced topics in mathematics.

Students takes a four-year English course. Grammar and composition is tackled by freshmen and sophomores, while journalism, and speech and drama are included in the junior and senior course respectively. Technical writing is also included in the freshmen English course. Philippine literature, Asian literature, world Literature, and contemporary literature are taught during freshman, sophomore, junior, and senior years, respectively.

Information and communications technology (ICT) is also a part of the curriculum. Freshmen, learn about computer fundamentals, digital design, and programming. Sophomores undergo a computer programming and applications course. Digital signal processing is learned by juniors. Data communication and networking is a part of the senior year.

Four years of Filipino language and literatures are required. Sining ng Pakikipagtalastasan (communication arts) courses are studied by freshman and sophomores. Juniors tackle pagbasa at pagsulat sa iba't ibang disciplina (reading and writing in different disciplines) while seniors learn about retorika (rhetoric). Included in their panatikan (literature) course are Ibong Adarna, Florante at Laura, Noli Me Tangere, and El Filibusterismo, which are tackled during freshman, sophomore, junior, and senior years, respectively.

Social studies and history classes are required. Philippine history, Asian history, world history, and the Life of Jose Rizal are taken up by freshmen, sophomores, juniors and seniors, respectively. Sociology, geography, economics, and political science are learned during freshman, sophomore, junior and senior, respectively.

Health and Physical Education courses are also required, with many activities to choose from.

Previously Values education was taught in RSHSs in freshman and sophomore levels, however the subject was removed from the RSHSs curricula in 2003. The subject was replaced by Technical Writing and Introduction to Statistics in freshman curricula and Statistics in Research in sophomore curricula.

Each of the 17 Regional Science High Schools are given by the government an allocation for Maintenance and Other Operating Expenses (MOOE) separate from other public high schools in the Philippines. The annual subsidy of RSHSs is divided as follows: 10% for the procurement of supplies and materials for mathematics, science and English, 15% procurement of instructional materials including textbooks for Science, Mathematics, English, and other subject areas, professional books, video materials and software in science, mathematics and English including internet subscription, 20% for procurement of science and mathematics equipment including the maintenance and repair of previously owned equipment and upgrading computers and printers, 12.5% will go for payment of electric and water bills, 25% for expenses for training/professional upgrading of all teachers, principals/OICs directly managing RSHSs, including attendance in seminars that may be sponsored by DepEd or other agencies; expenses for students participation in science and mathematics related activities, 12.5% for student researches and projects, and 5% for extra essential services such as security services.


Students of RSHSs receive a monthly stipend from the local government of its respective region. This monthly stipend is intended to support the academic expenses of the students such as research projects. Stipend of students vary from every RSHSs or maybe none at all like in Regional Science High School III, X as well as NCR.


Roughly 70% of alumni are in the sciences, engineering, and mathematics. The rest are in the humanities, journalism, law, business administration, accountancy, public administration, the military and religious ministry.
