History
Establishment and early years Cal Poly was founded in 1901 as the California Polytechnic School, following the signing of the California Polytechnic School Bill by Governor Henry Gage. The school began classes on October 1, 1903, with 20 students enrolled, offering three-year secondary-level courses.
Originally coeducational, the school enrolled 16 male and 4 female students.Morris Eugene Smith. A History of California State Polytechnic College, The First Fifty Years. Masters Thesis, 1958. pg. 13. In 1929, California Governor C.C. Young prohibited women from attending. Women were readmitted in 1956. By Fall 2023, female students constituted 50.1% of the total student population.
Transition to higher education In 1924, Cal Poly came under the control of the California State Board of Education. During the Great Depression, financial constraints led to discussions in Sacramento about converting Cal Poly into a state prison. It was saved by Julian A. McPhee, who went on to lead Cal Poly as its president for thirty-three years.
In 1933, the institution transitioned to a two-year technological and vocational school. By 1940, it began offering Bachelor of Arts degrees, with the first baccalaureate ceremony held in 1942. In 1947, the school was renamed California State Polytechnic College to better reflect its expanding higher education offerings. A Master of Arts degree in education was added in 1949.
Expansion and satellite campuses In 1938, Charles and Jerry Voorhis donated a farm and school to Cal Poly. In 1949, the W.K. Kellogg Foundation gifted an 812-acre horse ranch in Pomona, California. Originally a satellite campus for Cal Poly, the Pomona campus became an independent university, Cal Poly Pomona, in 1966.
Integration into the CSU system In 1960, control of Cal Poly in San Luis Obispo and other state colleges was transferred to the newly formed CSU system. That same year, a plane crash killed 22 of the 48 people on board, including 16 Cal Poly football players.
Authorized to offer Master of Science degrees in 1967, Cal Poly reorganized its curriculum from 1967 to 1970 into specialized schools: the School of Science and Mathematics, the School of Agriculture and Natural Resources, and the School of Architecture. In 1968, Cal Poly's FM radio station, KCPR, was launched as a senior project.
In 1971, the California State Legislature officially renamed the institution California Polytechnic State University. Since the 1970s, the university has seen steady enrollment growth and significant campus expansion.
Major donations and 21st century developments On May 3, 2017, Cal Poly received a $110 million gift from alumni William L. and Linda Frost, one of the largest donations ever made to public education in California.
In 2022, the university established the Noyce School of Applied Computing, combining three departments - electrical engineering, computer engineering, and software engineering - under one umbrella through donations received from the Robert N. Noyce Trust. In 2024, the school received a $60 million gift from the trust to establish an endowment, funding operations for the foreseeable future.
In 2024, the CSU system recommended integrating Cal Maritime with Cal Poly San Luis Obispo. On November 21, 2024, the CSU Board of Trustees approved the CSU Chancellor's recommendation. As of July 1, 2025, the two universities operate as a single institution: Cal Poly. On May 21, 2025, the university announced that Dr. Corey Cook had been named vice president and chief executive officer of Cal Poly, Solano Campus in Vallejo, and Rear Admiral (Retired) Eric C. Jones, USCG, had been named superintendent of the Cal Poly Maritime Academy, effective July 1. The full integration of academics will be completed in fall 2026 and all Cal Poly Maritime Academy and Cal Poly, Solano Campus students will be enrolled as Cal Poly students.

The property includes the main campus, two agricultural lands, and two sites in Santa Cruz County. The Swanton Pacific Ranch, a 3,200-acre ranch in Santa Cruz County, provides educational and research opportunities, encompassing rangeland, livestock, and forestry operations for the College of Agriculture, Food, and Environmental Sciences. It supports Cal Poly's "Learn by Doing" philosophy with an emphasis on sustainable agricultural practices and laboratory experiments. University House serves as the university president's residence.
The census-designated place is in the San Luis Coastal Unified School District. - Text list
21st century construction In the summer of 2018, a dormitory-style student community was completed at the corner of Slack Street and Grand Avenue. This development includes seven 3- to 5-story concrete-framed freshman residence hall buildings with 1,475 beds and an adjacent four-level parking structure. Community spaces feature a café, community room, game room, mail room, welcome center, offices, and maintenance shop. Additional site improvements provide a large open space for activities and group events, volleyball and basketball courts, and outdoor gathering areas.
The Warren J. Baker Center for Science and Mathematics was dedicated on November 1, 2013. This $119 million, six-story building replaced the aging "spider" Science Building 52 with a new 189,000-square-foot structure. It includes laboratories, classrooms, offices for the physics, chemistry, and soil science programs, and spaces for the Western Coatings Technologies Center and the Environmental Biotechnology Institute. The center also features Centennial Park, a landscaped central green area.
The William and Linda Frost Center for Research and Innovation was dedicated on May 5, 2023. The 102,000-square-foot interdisciplinary research center features state-of-the-art interdisciplinary laboratory and teaching spaces for students and faculty in the Bailey College of Science and Mathematics; the College of Agriculture, Food and Environmental Sciences; and the College of Liberal Arts.
Commuting Campus parking is limited, with 2,892 general-purpose parking spaces, 3,492 dorm resident spaces, and a total of 8,648 parking spaces.Parking Lot Survey Cal Poly University Police Department, October 18, 2011 The Facilities Master Plan acknowledges that, despite adding more parking spots, the ratio of parking to students will decrease due to expected enrollment growth.Cal Poly Campus Master Plan Cal Poly Facilities Planning and Capital Projects, March 21, 2001 To address this, the plan emphasizes reducing demand for individual vehicle parking by constructing additional dorms and enhancing campus life. Cal Poly Commuter and Access Services has successfully promoted alternatives to single occupancy vehicles, with bus use more than doubling and bicycle use nearly quadrupling from 2002 to 2012.

Bachelor's projects All undergraduate students are required to complete a senior project, a capstone experience integrating theory and application from their undergraduate studies. Projects may include design or construction experiences, experiments, self-guided studies or research projects, presentations, reports based on internships or co-ops, public portfolio displays, or performances. These projects often lead to job offers or recognition. Notable examples include Punchd, acquired by Google, and Jamba Juice, inspired by a senior project idea.Collaboration Packs a Punch at Poly: Google Acquires Punchd, a Cal Poly Senior Project , Cal Poly Magazine (Fall 2011), accessed October 8, 2011.Blended Bliss, Cal Poly Magazine (Summer 2007), accessed October 18, 2011. The campus area known as 'Architecture Graveyard' hosts many senior projects, including experimental and unconventional structures.
