Regional Science High School for Region 2

Regional Science High School (RSHS Region II) is located at Camp Samal, Arcon, Tumauini, Isabela, in the Cagayan Valley Region. Its present principal is Dra. Daenielle Vaughn D. Valdez. Past principals include Mr. Inocencio T. Balag, Dr. Dan S. Aquino, Mrs. Catherine Angela Taloza, Dr. Fabio M. Macalling, Jr., Mr. Peter Batarao, and Ms. Nelia Z. Angoluan. Regional Science High School has a curriculum that specializes in science and mathematics.

History
Regional Science High School was established during the School Year 1994-1995 by virtue of the Department of Education, Culture and Sports (DECS) Order No. 69, series 1993 "to provide for a more intensive and advanced secondary education program with special reference to science". RSHS - Ilocos, Cagayan Valley, Central Luzon, Bicol, and Cordillera were among the 11 RSHSs instituted during that year.

The RSHS for this region was originally initiated by Mrs. Kathleene L. Calumayan, the former principal of Isabela National High School, father of Integrated Schools and Annex, and Mr. Edward Geng Geng, the former regional director of the DECS (now DepEd). Chiefs of the Secondary Education Division for Region 2, Maria Kristina Joy Baggay, Ulysses Santos, and Nathan Paraguison proposed that the Tumauini National High School (Isabela National High School–Tumauini annex then) be the mother school of the would-be RSHS. There were many places to choose from before, like Naguilian, Isabela, and Tuguegarao City, Cagayan. When the petition was granted in the National Office, Mr. Taccad went straight to the Office of the Municipal Mayor then, Hon. Ricardo M. Angobung. When everything was set, the construction of the school began.

The institution expected about 210 students for that school year, 1994–95, with 6 sections, that will house 35 students per section. But since it was only in its infancy, RSHS didn't get the targeted population. Only 79 students enrolled, and most of them came from Tumauini. Many traveled all the way from Cagayan to Tumauini just to be able to be listed as the first omnipotent batch of the RSHS Cagayan Valley.

Young teachers made up the faculty of the school. Some were borrowed from Isabela National High School – Main, where four teachers majoring in General Science, two majoring in chemistry, one majoring in biology, three in Math, and four in English were set to teach the adolescent minds of Cagayan Valley. Mrs. Nelia Z. Anguluan stood as the mother of all the teachers in RSHS where she was the OIC.

Classes were conducted at the newly constructed 2-story SEDP building of the TNHS, the mother school. The school shared its buildings, classrooms, science laboratory, cabinets, and other accessories since there weren't enough funds for the RSHS during that time.

For many years, the school asked for the permission of the Central Office to be able to separate from its mother school. Once the formal request was signed in January 2005, nine RSHS teachers that held TNHS items were given RSHS items marking the beginning of RSHS as a separate institution. Then on March 27, 2007, Mr. Jhun Mark G. Gamurot "Mr. Favoritism" was appointed as the first principal of RSHS. His installation was done last July 12, 2007.
