Flagstaff High School (FHS) is a secondary school in Flagstaff, Arizona. Flagstaff High School has been opened to the public since 1923. FHS is a four-year public high school of approximately 1,500 students. The students are primarily of five ethnic groups: White, Native American, Hispanic, Asian, and African-American. Approximately 50 percent of the students are minorities; 147 are from various Native American tribes and live at the Bureau of Indian Affairs KinLani Dormitory. The student body represents a broad socio-economic range from low income to upper middle class. Each year approximately 50 percent of the graduates enroll in four-year colleges and universities and 25 percent in two-year institutions.
In addition to sections of Flagstaff, the school serves sections of the Navajo Reservation: Birdsprings, Leupp, and Tolani Lake.
It also includes Bellemont, Fort Valley, Kachina Village, Mormon Lake, Mountainaire, Munds Park, and Oak Creek Canyon, as well as portions of Blue Ridge.
There is a tribally-controlled dormitory facility contracting with the Bureau of Indian Education (BIE), Flagstaff Bordertown Dormitory, which houses Native American students who attend Flagstaff High.
Prior to the establishment of Sedona-Oak Creek Unified School District, Flagstaff High directly included Sedona in its attendance boundary, and took students from the Red Rock school district, which did not operate any schools.
