Prior to the establishment of Catalina Foothills, some district students attended high school in Tucson Unified School District and the rest primarily in the Amphitheater district. The establishment of Catalina Foothills was postponed several decades due to the ability of district students to attend high school in neighboring school districts. As the population grew in the area, a large core of Catalina Foothills students attended Amphitheater High School in North Tucson, as the closer Canyon del Oro High School in Oro Valley was virtually closed to out-of-district students. As the Amphitheater district began to experience overcrowding, the need for a high school in the Catalina Foothills School District became apparent. Construction began in 1991 on a site centrally located in the district. The Catalina Foothills School Board had acquired the site in the late 1970s. The school opened to the ninth grade in 1992 when classes met at a district middle school. In 1993 campus was opened to ninth and tenth graders, and the first graduating class of Foothills High walked in late spring 1996.
