Salag National High School, with school ID 312430, is situated in Salag, Tabogon, Cebu, Philippines. In 2009, Salag National High School was established. At first, it catered only to first-year high school students, with Mr. Edsel M. Ursal as the first school administrator to ever set foot in Salag to serve the community. The one-storey three-classroom school building from Salag Elementary School was utilized to serve as classroom and offices of the newly opened high school in Salag.

Barangay Salag is one of the mountain barangays in the municipality of Tabogon with access to nearby sea where most local population depends on farming root crops, banana, corn and coconut with some locals living near the seashore for fishing.
