Update: On November 26, 2018, the California State University announced an extension to the fall 2019 priority application period. The deadline is now Saturday, December 15. This article has been amended to reflect this change. Learn more about the extension.

On October 1, 2018, the California State University opened the priority application period for students to apply to all 23 campuses for the fall 2019 semester. All students who want to attend a CSU campus must apply for admission through Cal State Apply.

That application period is now winding down and will close on December 15, 2018, at 11:59 p.m.

There are good reasons to get your application sooner rather than later. It's especially important to apply during this priority admission cycle (in other words, before December 15) if the campus or degree program you're interested in is "impacted," meaning there are more qualified applicants than there is space to accommodate them.

If you're not sure whether the campus(es) and/or degree(s) you'd like to attend are impacted for 2019-20, check the Impaction section of Calstate.edu. There are some campuses at which all undergraduate programs are impacted: Cal Poly San Luis Obispo, Fresno State, CSU Fullerton, CSU Long Beach, San Diego State, and San José State.

Impaction doesn't mean you will not get into a program or campus, but it does mean that campuses will look at where you went to school, among other factors. Applicants who are local to an impacted campus are given priority.

(If you've applied to the CSU in the past, you may want to learn what's different about Cal State Apply for this application cycle.)

Be sure to build in time to talk to a counselor or your parent or guardian if there's information you'll need from them to complete your application. (Want to know what happens after you submit your application? Learn what to expect next.)
