Grossmont High School is the oldest high school in San Diego’s East County. Its mascot is the Foothiller, so chosen because, at the time of the school’s construction, East County was much more isolated from the rest of San Diego than it is today and was often referred to as “the boondocks” or “the foothills.” Grossmont is one of ten regular high schools in the Grossmont Union High School District, which also oversees a charter high school and a continuation high school. The school has an approximate enrollment of 2,400 students.
Grossmont High School has been accredited by the Western Association of Schools and Colleges (WASC) since 1962. The current accreditation is valid through 2008.
Grossmont is listed as being in El Cajon but is actually right on the border of La Mesa and El Cajon. The majority of the student body is from the La Mesa area. Grossmont High School's rival is Helix High School.
