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.
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.
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.
