There are subtle, yet important, differences between major and campus impaction. Major impaction means that the number of applications from fully eligible students to a designated program or major on a CSU campus during the initial filing period exceeds the number of spaces available in that major. However, students can still be admitted to the campus in an alternate major or they may eventually be admitted to the over-subscribed major provided they meet the supplementary admission criteria.
Students interested in an impacted major or campus must apply for admission during the initial admission application filing period (October 1 through November 30 for fall admission). Applicants to majors that are impacted should apply to additional CSU campuses to maximize opportunity for admission. Impacted majors and campuses accept no applications for admission after the initial filing period.
