Caraga Regional Science High School is a public school in San Juan, Surigao City, Philippines. It 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.

DepEd Caraga Region 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, Surigao City.

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 San Juan National High School.

For the first two years, CRSHS shared the roof of SJNHS which is now known as Surigao City National High School as it had no building of its own. CRSHS is a sister/brother of SCNHS. 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 science and computer laboratory rooms.

CRSHS started its humble beginning with 120 freshmen qualifiers mostly coming from the elementary schools of the same division (Division of Surigao City) 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 as 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.

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, Research, 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, Research, 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.

Regional Science High Schools implement a curriculum which is different from Regular High Schools (which uses RBEC curriculum), 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 school offers a highly 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 languages, 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 tackle earth & environmental science, and Introduction to Physical Sciences (Physics & Chemistry). Biology, Chemistry and Physics is introduced during second year. Sophomores tackle the areas of botany, inorganic chemistry, and mechanics. Zoology, organic chemistry, and thermodynamics is studied by juniors. Seniors have human biology, analytical chemistry and electricity, electronics, electromagnetics, and vectors.

In mathematics, students takes 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 are taken during sophomore. Differential and integral calculus and Differential equations, and Advanced Statistics are learned by juniors. Seniors tackle 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.
