The less popular CSUs have had declining enrollment trends for many years. A decade or so ago, most CSUs were impacted, meaning that they had competitively-determined admission thresholds (based on a GPA and SAT/ACT formula before COVID-19, now basically GPA plus whatever points for extra academic course work, etc.) were applied. Now, most CSUs are non-impacted, so they admit at the CSU baseline (a-g courses completed, 2.5 recalculated HS GPA for California residents, 3.0 for non-residents), although they may have a few majors like nursing that are impacted and therefore competitive admission.
