The Regional Science High School for Region 2 traces its origins to the 1994–1995 school year, when it was established as an annex of Isabela National High School. It was initially housed at Tumauini National High School, which served as the mother school during its formative years.
In its first year of operation, the school admitted 79 pioneering students, most of whom came from Tumauini, Isabela. Several others traveled from neighboring provinces such as Cagayan, reflecting the school's emerging regional significance as a center for advanced secondary education in science and mathematics. During this period, Ms. Nelia Z. Anguluan served as the Officer-in-Charge (OIC), overseeing the school's early development.
Classes were conducted in a newly constructed two-story Secondary Education Development Program (SEDP) building within the Tumauini National High School campus. Due to limited financial resources, the school shared facilities—including classrooms, science laboratories, and educational equipment—with its mother institution.
The RSHS Hymn, which symbolizes the school's identity and spirit, was inspired by the Our Lady of Guibang Hymn, reflecting the cultural and spiritual heritage of the region.
Later on, the school transferred to its permanent site at Camp Samal, Barangay Arcon, Tumauini, Isabela, where it continues to stand today as a hub for science-focused secondary education in Cagayan Valley.
As one of the pioneering Regional Science High Schools in the country, RSHS Region 2 has consistently upheld a legacy of academic excellence. It remains one of the top-performing secondary schools in the region, excelling in various local and national competitions in mathematics, scientific research, campus journalism, and even sports. This well-rounded performance highlights the institution’s commitment to producing not only academically gifted students but also well-rounded individuals.
Over the years, the school has been led by a number of dedicated administrators. Notable past principals include Inocencio T. Balag, Fabio M. Macalling Jr., Peter Batarao, Nelia Z. Anguluan, Evelyn Bumanglag, and Romel L. Ricardo, whose leadership has contributed to the sustained growth and prestige of the institution.
