Yes, you must apply directly to a specific major at Cal Poly San Luis Obispo. Each programme has its own GPA and course expectations, there is no undeclared admission, and changing majors later is difficult. Check the official admissions page for your intended major.

Common Reasons Applications Struggle

  • A late or incomplete CSU application.
  • An application that shows poor alignment with the chosen major.

My Advice

Choose your major carefully and check its prerequisites before you apply, because switching later is hard. Admission rates change from year to year, so verify the latest expectations for your major on the official Cal Poly page before your 2027 or 2028 intake.
