The first term at Provo High School began in 1912, after a special election favored a $1 million levy to furnish the city with a high school building and equipment.
In 1912, the high school provided only one year of schooling beyond the eighth grade but it soon provided two years. By approximately 1914, the eighth grade had become part of the high school, giving the high school grades eight through ten. In 1917, the eleventh grade was added to the curriculum. In 1921, Provo High School began graduating students. Two junior high schools were opened in 1931 (Farrer and Dixon); they took grades 7-9, which had already been organized into a separate school sometime earlier. (The junior high and High schools shared the same facilities for several years).
The first high school building was constructed in 1919, with major additions and improvements the following year. It appears that prior to the construction of the high school building, classes were held at the Central School on the same block. Once the building was completed in 1920, it became apparent that there was a need for an auditorium; three years later, an auditorium was built for the high school. Another three years passed, and the Science and Arts building was added to the campus.
The high school located on University Avenue was constructed and occupied in 1956 until 2020. The new high school was then built in west Provo.
