Caraga Regional Science High School

The Regional Science High School Union (RSHS-Union) is a specialized system of public secondary schools in the Philippines, established during the academic year 1994–1995. It is operated and supervised by the Department of Education, with a curriculum heavily focused on math and science. It remains within the ambit of the Department of Education, unlike the specialized science high school system of national scope, the Philippine Science High School (an attached agency of the Department of Science and Technology).
