For the first 31 seasons of Boise State football, the Broncos competed at the two-year junior college level. From 1933 to 1964, the school was known as Boise Junior College, then from 1965 to 1967 it was known as Boise College.
Boise Junior College football started in 1933, one year after the school's establishment. The team initially competed at Public School Field before moving to the on-campus College Field (also known as Chaffee Field) in 1940. Under head coaches Dusty Kline, Max Eiden, and Harry Jacoby, the Broncos only saw modest results. In the early 1940s, the program was disrupted by the outbreak of World War IIâÂÂin 1941, coach Jacoby was called into Army service, forcing George "Stub" Allison to fill in for the remainder of that season. In 1942, the program was forced to go on hiatus due to depleted male enrollment at the college. In 1946, with the war over, the program returned under Jacoby, and in 1947 first-year assistant Lyle Smith was promoted to head coach.
Boise saw tremendous success under Smith, who won his first 37 games as a head coach (interrupted by a period in 1950 and 1951 in which he was recalled into Naval service in Korea and George Blankley took over as head coach and also saw success). The program moved into a new stadium, Bronco Stadium, in 1950. Success for the Broncos continued throughout the 1950s under Smith, culminating in a NJCAA national championship in 1958. That success continued well into the 1960s, with the Broncos ultimately earning 13 Intermountain Collegiate Athletic Conference football titles, by far the most in that conference's history.
By the mid-1960s, in response to tremendous growth, the school began the transition into a four-year institution. In 1965, the school began offering baccalaureate degrees and changed its name to Boise College. 1967 was the final year for Boise at the two-year level as they moved to the NAIA as an independent. It was also Smith's final year as a coach, as he moved full-time into the athletic director role at Boise. Smith did not suffer a losing record in any of his twenty seasons as head coach.
In 1968, Boise College became Boise State College, and the football program began four-year competition under new head coach Tony Knap, Smith's teammate (in the late 1930s) at the University of Idaho.
