Admissions standards at California State University, Fullerton require undergraduate applicants to meet baseline California State University eligibility index thresholds, which generally demand a minimum unweighted high school a-g course GPA of 2.50 for California residents and 3.00 for out-of-state applicants. However, because CSUF is heavily impacted across a large percentage of its undergraduate programs, the realistic competitive grade point average required to secure admission into popular majors is typically much higher, often ranging between 3.4 and 3.8 weighted.
