San Joaquin Delta College is the successor of the Stockton Junior College that formed in 1935. The success of the operation was so notable that the College of the Pacific, now University of the Pacific, abandoned freshmen and sophomore instruction in 1936, bequeathing all instruction to the junior college.
The two institutions shared facilities through World War II, when the junior college added another unique, although temporary, feature: running an aviation school in Nevada.
Stockton Junior College became Stockton College in 1948, with the total student body at just under 2,000. The physical change was even more evident, with classes being moved to a 43-acre site just south of College of the Pacific. The educational pattern also changed, as the Stockton School System restructured into six years of elementary instruction, four of junior high, and four combining the junior and senior years of high school with the freshman and sophomore years of college.
The college's vision is the faculty, staff, and students of San Joaquin Delta College envision a community of learners who pursue and achieve ever higher educational goals, commit themselves passionately to life-long learning, and fully appreciate the diverse and dynamic world around them.
