Questions about impaction or applying to the major?

Major impaction means that the number of applications from fully eligible students to a designated major during the initial filing period far exceeds the number of spaces available in that major. However, students can still be admitted in an alternate major, or they may eventually be admitted to the oversubscribed major if they meet the supplementary admission criteria.

The Chancellor's Office of the California State University has granted the Psychology Department impaction status for its undergraduate major program. Students applying to the major are required to submit a supplemental application. New applicants, including transfer students, must be admitted to the University prior to applying to the major.
