How admission works
- Every major at SDSU is impacted: there are more eligible applicants than spaces, so meeting the CSU minimum does not guarantee admission.
- Freshmen from high schools in San Diego County south of State Route 56 and in Imperial County are local applicants and get priority. Transfer students from Cuyamaca, Grossmont, Imperial Valley, San Diego City, Mesa, Miramar and Southwestern colleges are local transfers.
- Like most CSU campuses, SDSU uses the CSU admission GPA, calculated from 10th–12th grade a-g courses with extra points for up to eight semesters of honors courses. SDSU does not publish its cutoff for each major.

CSU counts every application submitted, including ones later withdrawn, left incomplete or not meeting minimum eligibility, so admit rates among complete applications are somewhat higher. “Non-residents” includes out-of-state and international applicants. “<10” means CSU did not report a group smaller than 10.
