The current building opened in 1952, though the school itself has been in operation since 1897. Idaho Falls is the older of the two traditional high schools, the other is Skyline, in the Idaho Falls School District#91. The school colors are orange and black and its teams are the Tigers; the mascot is known as "Sampson".

As the oldest high school in Idaho Falls, IFHS was established in 1897. The first building was a three-story structure on the corner of North Water and Walnut Street, behind what later became O. E. Bell Junior High School. Following the construction of a larger building that occupied the entire block between 6th and 7th Streets and S. Boulevard and South Lee Avenue (where the Wesley W. Deist Aquatic Center is presently located), the original school building became the school district administration building and was also used for overflow classrooms as part of O.E. Bell Jr. High. It was later razed and is now part of the parking lot behind the present O.E. Bell office building. When the current campus on South Holmes Avenue opened in 1952, the building on 7th Street became Central Junior High School, which burned down on 24 April 1973. The Civic Auditorium was concurrently constructed by the city in 1952, adjacent to the then-new Idaho Falls High School, and remains a major center for performing arts in the area. The school newspaper is the Tiger Times and the yearbook is The Spud Annual. Paul Haack wrote the school song. "Dear Old I.F. High", in 1927. The school district added the freshman class to the high schools in August 2012.

The demographic breakdown of the 1,298 students in 2024–2025 was: • Male - 51.2% • Female - 48.7% • Native American/Alaskan - 0.3% • Asian/Pacific islanders - 0.6% • Black - 0.3% • Hispanic - 18.6% • White - 74.7% • Multiracial - 5.2% 30.8% of the students were eligible for free or reduced price lunch.
