Caraga Regional Science High School is a public school in San Juan, Surigao City, Philippines. Caraga RSHS is the leading school in the Division of Surigao City with high MPS during the annual National Achievement Tests (NAT), and has been consistent in making its name in Division, Regional, National and International level contests.


The birth of the DepEd Caraga Administrative Region or Region XIII on February 23, 1995 by virtue of the Republic Act No. 7901, required the establishment of a Regional Science High School with a permanent site.

Regional Director Sol F. Matugas tasked City Schools Division Superintendent, Dr. Glorina Mongaya-Tremedal, to seek support from former Surigao City Mayor Salvador Sering who agreed with the idea and so donated an area of 10,000 sq.m. located at the portion of Barangay, San Juan.

The Caraga Regional Science High School made Matilde J. Manliguis, appointed by Director Matugas, as head of the school aside from her designation as the principal of the SJNHS.

For the first two years, CRSHS shared the roof of San Juan National High School as it had no building of its own. The realization of the school building took over a year considering that the location was still swampy. Finally in 1999, it transferred to its new site with a six classroom building with a science and a computer laboratory rooms.

CRSHS started its humble beginning with 120 freshmen qualifiers mostly coming from the elementary schools of the same division and the nearby towns. The number of students gradually decreased yearly until what was left on its fourth year were the 49 students who became the pioneering graduates.

In 2003-2004, DepEd Caraga granted CRSHS the permission to operate a separate secondary school. CRSHS caught the attention of the entire nation when it maintained its place as topnotcher in the National Secondary Achievement Test (NSAT); consequently, putting the school in the Hall of fame.

In S.Y. 2012-2013 the school adapted to the new K-12 Curriculum and pioneers of this curriculum were introduced as "Grade 7 or 7th Graders" these students successfully completed and became the first Junior High School Completers of the school in S.Y. 2015-2016. The first batch of "Grade 11 or 11th Graders" will be introduced in S.Y. 2016 - 2017, The pioneering batch of K-12 Curriculum will graduate Senior High School in S.Y. 2017 - 2018.

In S.Y. 2015-2016 Ms. Ma. Luisa Guyano from Surigao City National High School replaced Mrs. Manliguis as the School Principal after the former principal retired.

Admission and Retention[edit]

Admission to CARAGA RSHS (Junior High)[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 will be 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. It would be conducted by the RSHS screening committee. The interview shall be rated in accordance with a prepared rubric and shall be an integral part of the score obtained by the student.


A student should obtain a final average grade of at least 85% in English, Mathematics and Science, with no grade lower than 80% in any of these subjects, in any grading period, and a final grade of 83% in the rest of the subjects. 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 before of increasing the cut-off grade in Science, Math, and English subjects from 85% to 88% and the rest of the subjects from 83% to 85%, however this wasn't implemented due to some circumstances.


Only students who have maintained the grade requirement set for RSHS shall be 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.
