Admission to UC San Diego as a freshman does not guarantee admission to engineering majors at the Jacobs School of Engineering. Due to high demand, all engineering majors at UC San Diego are considered "capped" for incoming freshman applying for enrollment, which means additional screening procedures are in place. Admissions for all incoming students to UC San Diego is managed by the campus-wide UC San Diego admissions office which has a capped majors page.
For transfer students applying to engineering majors, note that all engineering majors are "capped," meaning that admission to UC San Diego does not guarantee admission to these majors. Admissions for all incoming transfer students to UC San Diego is managed by the campus-wide UC San Diego admissions office which has a transfer admission page.
Current UC San Diego students who wish to move from a non-engineering major into an engineering major, or from one engineering major to another engineering major, are considered "continuing students." More information:: "My Jacobs School of Engineering Major Change Application."
