opened in 1913 at the present site of L. M. Prince School and Amphitheater Middle School on East Prince Road near North Stone Avenue. The school expanded to include four additional classrooms in 1924. By 1928, the district established the Amphitheater Carnival, an annual community event that endured until 1958. By 1934 district enrollment had grown to over 500 students from 48 students in 1919. By the 1930s, district residents desired the establishment of a district high school rather than continuing to send district high school students to Tucson High School in the Tucson Unified School District located near the University of Arizona in central Tucson. Using a combination of state and federal (Works Progress Administration) funding, Amphitheater High School was completed in 1939 on East Prince Road under the direction of E.C. Nash, the district's first superintendent appointed in 1937. Amphitheater High School became Tucson's second high school. The Amphi district experienced gradual population growth, ultimately being dubbed Tucson's first suburb in the 1930s by the Arizona Daily Star newspaper. As residential and commercial growth progressed northward along the Oracle Road corridor, additional school sites were developed. The district boundaries and population continued to expand with the growth of the Tucson area, and by 1942, the district extended north of the Rillito River into the foothills of the Santa Catalina Mountains north of Tucson. By 1943, the district boundaries were finalized and extended north to the Pima County line. Dramatic growth transformed the district in the 1950s from a rural district into one of relatively urban character. Marion Donaldson was hired as district superintendent in 1951 and served in such a capacity until 1967, directing the development of the district. Donaldson brought innovation in educational programs that received national recognition and also championed the construction of new schools in a community with a very limited tax base. A new junior high school was constructed with federal funds and later bond money, opening on September 8, 1952. In 1955, the junior high on West Yavapai Road became the campus for Amphitheater High School and the old senior high school building on East Prince Road became Amphitheater Junior High School. The tremendous growth in the Tucson area following World War II in the 1950s prompted changes in the district. A divide gradually emerged in the district between the urban neighborhoods of North Tucson and the increasingly affluent suburbs north of the
