Looking back to Class of 2025 data, 49% of attending students were in the top decile of their graduating high school class; 82% were in the top quartile. The average weighted GPA for enrolled students that year was 4.01. Back when standardized tests were still considered, the mid-50% ACT range was 28-33 and the equivalent SAT range was 1240-1420.

How Cal Poly SLO Rates Applicants

There are only two factors that this school ranks as “very important” to their admissions decision process and they are: the rigor of your courses and GPA earned within those courses. They “consider” items such as: extracurricular activities, talent/ability, first-generation status, geographical residence, volunteer work, and paid work experience.

Cal Poly, along with all other California State University campuses have gone test-blind, meaning they will no longer consider SAT or ACT scores in the application process. Previously, test scores had been a “very important” component of the review process at Cal Poly.

In the words of the admissions office:

  • “For the purposes of your application, we’ll consider your 9th-11th grade weighted GPA. That number is calculated from college-prep coursework as designated on your application. Weight is granted for courses designated as ‘honors,’ ‘college-level,’ ‘advanced placement’ or ‘international baccalaureate’ for up to eight semesters.”
  • “Cal Poly takes activities such as work experience, internships, volunteer programs and extracurricular activities into consideration. We are also interested in any leadership roles you may have held in these activities.”
  • “All candidates are objectively evaluated by the cognitive and non-cognitive variables under our faculty-mandated Multi-Criteria Admission (MCA) process.”

Tips for Applying to Cal Poly

If you plan on joining the nearly 59,000 Mustang freshmen hopefuls for the next admissions cycle, you should also know the following:

  • This university does not offer interviews or consider recommendations, essays, or demonstrated interest.
  • You will be required to select a major from a list of more than 60 on your application.
  • Applications can be submitted any time from 10/1 through 11/30.
  • There are no essays for applicants to Cal Poly SLO.

Should I Apply to Cal Poly?

If you earned a 4.0 (or better) weighted GPA in high school, you are a viable candidate to any program within Cal Poly –San Luis Obispo. Students with a 4.1 or 4.2 in a mostly honors/AP curriculum will fare best. That said, very few students are able to consider Cal Poly as a “safety” these days; all students need to make sure that they formulate an appropriate college list, containing a complement of “reach”, “target”, and “safety” schools. You’ll definitely want to do this in collaboration with an admissions professional who is aware of the latest trends and strategies associated with your prospective colleges.
