In 1893, the Regents of University of California adopted the extramural instruction plan, which officially founded University Extension. In 1902, University Extension was reorganized as a self-governing body within the University. The doors of UC Extension in Los Angeles (officially “University of California Extension Division, Southern District”) were opened in September 1917. By 1919, more than 1,600 students attended almost 100 classes. Today, UCLA Extension offers multiple academic certificates and courses in 11 departments.
