Cal Poly SLO Admission Requirements and Selection Criteria

Cal Poly SLO utilizes a unique "Multi-Criteria Evaluation" (MCE) process that differs significantly from most other California State University campuses. While other campuses rely primarily on GPA and course completion, Cal Poly evaluates applicants based on a localized scoring system tailored to specific majors and colleges.

Core Evaluation Metrics

A-G Coursework Completion: Completion of foundational high school courses with a minimum grade of C or better.
GPA Calculation: Calculated using all transferable college-preparatory coursework completed in 10th and 11th grades, including approved honors and Advanced Placement (AP) courses.
Major-Specific Preparation: Rigorous evaluation of math, science, and technical coursework completed relative to the applicant's chosen major within the College of Engineering, College of Agriculture, Food and Environmental Sciences, College of Architecture and Environmental Design, Orfalea College of Business, College of Liberal Arts, or College of Science and Mathematics.
Extracurricular Engagement & Work Experience: Documented hours spent in leadership roles, work environments, community service, and major-relevant extracurricular activities.

Verification Notice: Cal Poly SLO, along with the entire CSU system, remains test-free for undergraduate admissions. SAT and ACT scores are not used in the evaluation or admissions selection process and should not be submitted.
