Seton Catholic Preparatory High School

Seton Catholic Preparatory is a college preparatory, co-educational Catholic high school in Chandler, Arizona, United States. Named after St. Elizabeth Ann Seton, the school was established in 1954 and is staffed by the Sisters of Charity of Seton Hill. History Originally known as "Seton High School" or later as "Seton Catholic High School", the school opened in 1954 in downtown Chandler. Initially founded as a parish school, Seton began to operate under the supervision of the Diocese of Phoenix as a diocesan school beginning in 1973. On September 12, 1980, a fire begun by one of the students destroyed much of the old campus, including eight classrooms in two buildings; the school would temporarily operate from the remaining classroom building, administration building, and gym. The fire, which caused $800,000 in damage, was found to have been started by three minors—one a student—after the latter got into an argument with a teacher. At the time of the fire, the school had 130 students. After the fire, the school opted to relocate from downtown Chandler to a site more centrally located to serve the growing cities of Tempe, Mesa, and Chandler, which would allow the school to increase its enrollment. The school moved into the so-called Tri-City Campus in 1983 (and was even known as "Seton Catholic Tri-City High School" for a time in the 1980s); the former site was converted into a Boys and Girls Club. That fall, the school reached a then-all-time high for enrollment, 259 students.
