Impaction at the CSU

As you get ready to apply to the CSU, you may find that a campus or undergraduate major you're considering is "impacted," meaning there are more applications from qualified applicants than there are available spaces. If you're interested in an impacted major or campus, be sure to apply for admission during the initial filing period, October 1 to November 30.
