The California State University (CSU) System and Cal State Apply, Explained

What the CSU system is (and how it differs from UC)

The California State University (CSU) is one of the two public four-year university systems in California, alongside the University of California (UC). It is a large, access-oriented system of campuses spread across the state, offering thousands of undergraduate and graduate programs with a strong focus on teaching, applied fields and workforce-ready degrees.

The CSU is a separate system from the UC, with its own admission rules, its own application portal and its own eligibility standards. Applying to a CSU campus does not put you in the UC pool, and vice versa — they are entirely different applications.

One structural change to note: a planned integration of Cal Poly and Cal Maritime takes effect in Fall 2026, which changes the exact number of standalone campuses. Because system structure and campus lists can change, confirm the current campuses and programs on the official CSU site.

Cal State Apply: one application for every campus

Cal State Apply is the single, centralized application used for every CSU campus. You create one account, enter your coursework and information once, and can add multiple campuses (and, at some campuses, specific majors) to the same application.

The application has a defined filing period each year. Historically the freshman priority period runs from October 1 to November 30 for the following fall, though some campuses extend deadlines when space allows. Always check the current dates and any campus-specific extensions on the official portal before you rely on a date.

• One account, one coursework entry, many campuses
• Applying to more campuses means more application fees (verify the current per-campus fee on the official site)
• Some campuses admit by major, so the major you select can matter

Freshman eligibility: the a-g pattern and GPA

CSU freshman eligibility is built on the 'a-g' subject pattern — a 15-unit sequence of college-preparatory courses (English, math, science, social science, language other than English, visual/performing arts and electives), each completed with a grade of C or better.

Eligibility is then determined largely by your a-g GPA. Under current policy, California residents and California high-school graduates who reach a stated a-g GPA threshold are eligible; applicants in a lower GPA band may be evaluated using additional 'supplemental' factors rather than being automatically excluded.

Because the exact GPA cutoffs and supplemental-factor rules are set by the system and updated over time, treat any specific number you see elsewhere as provisional and verify the current thresholds on calstate.edu/apply.

Test-free admission (no SAT or ACT)

The CSU is test-free for admission. Following a 2022 amendment to Title 5, the SAT and ACT are not used to determine admission eligibility at any CSU campus. You do not need to submit SAT or ACT scores to be admitted.

Scores can still play a limited, post-admission role: if you are already admitted, a campus may use SAT/ACT results (alongside other measures) to help place you into the appropriate first math or written-communication course. That is a placement use, not an admission gate.

This is a real point of difference for many applicants: your record of a-g coursework and grades carries the weight that test scores might elsewhere.

Impacted campuses, impacted majors and the MFAS

When a campus or a specific major receives more qualified applicants than it has space for, it is designated 'impacted.' Impacted campuses and majors can apply higher standards — for example a higher a-g GPA threshold and additional criteria — than the systemwide minimum.

To evaluate applicants beyond the baseline, campuses use a Multi-Factor Admission Score (MFAS): a combination of a-g GPA and campus-selected supplemental factors. The specific factors and their weights are published per campus, so the same profile can be evaluated differently at different CSUs.

Many campuses also give an admission advantage to applicants from their designated 'local admission area.' If a program is impacted, read that campus's supplemental-factor page carefully and apply early in the filing period.

Applying well: a practical checklist

Start by confirming which CSU campuses and majors fit your goals, and whether any of them are impacted for your intended major. That single fact often shapes your whole strategy.

Enter your a-g coursework carefully and completely in Cal State Apply — accuracy here directly affects your calculated a-g GPA. If you are applying to campuses that admit by major or that are impacted, review each one's supplemental factors before you submit.

• Confirm campus list, majors and impaction status on the official site
• Enter a-g coursework accurately (it drives your a-g GPA)
• Check each impacted campus's supplemental factors and local-area rules
• Apply within the priority filing period; note per-campus fees
• International applicants: verify English-proficiency and transcript requirements per campus
