How admission works
- Cal Poly admits by major, and admission is competitive in every major. You compete only with applicants to the same major.
- Unlike most CSU campuses, Cal Poly uses your 9th–11th grade weighted GPA in college-prep courses, with extra weight for up to eight semesters of honors, AP or IB courses. Ninth-grade grades count.
- Cal Poly's Multi-Criteria Admission also considers courses beyond the minimum requirements, work experience, internships, volunteering and extracurricular activities.
- Applicants from high schools in San Luis Obispo County, northern Santa Barbara County and southern Monterey County can receive extra points as local applicants.
