The school started with a single classroom consisting of 60 bright students coming from different provinces in the Ilocos Region, with Dr. Igmedio M. Cariaga as principal. For almost four years, it shared classrooms with its mother school DFLOMNHS located at National Highway, San Blas, Bangar, La Union. Then in July 1998, RSHS moved to its present site at Ma. Cristina East, Bangar, La Union. The RSHS-1 campus was donated by the Municipal Government of Bangar.
Admission to any RSHS is a three-step screening given to all qualified elementary students. To be eligible for admission, applicants must be Filipino students who belong to the top 10% of the graduating class and must have special aptitude in science and math. The screening includes two examinations and one interview.
Regional Science High School for Region 1 is one of the top high schools in the National Secondary Assessment Test (NSAT) and National Achievement Test (NAT). Likewise it also maintains a high passing rate in college entrance examinations from top caliber universities in the Philippines, such as: University of the Philippines College Admission Test (UPCAT), Ateneo de Manila University College Entrance Test (ACET), De La Salle University College Entrance Test (DLSU-CET), University of Santo Tomas College Entrance Test (UST-CET) and Saint Louis University- Baguio City College Entrance Examination (SLU-CEE).

The RSHS Library supports the students by providing resources ranging from traditional print and microform to electronic subscription e-journals and databases. Located on the administrative building, the library is composed of the General Library, which stores encyclopedias; the Natural Science Section which covers sciences, mathematics and ICT; the Human Sciences Library which covers history, languages and literature, and other fields of social sciences; and the Multi-media and Internet Library.
The school has also one covered court where sports activities and other productions are held. Construction of the facility began in 2001 as part of the project of the 5th batch of SCIons (class 2002).
Recent expansions include a two-storey Grade 7 building, with a PTA dhaving ing, an air-conditioned School Clinic, and a school museum called GASERA. A four-storey Senior High School Building now accommodates Medical and Engineering (STEM)-focused senior high programs.
