UC vs CSU: they might have similar letters, but they're definitely not the same thing! The University of California and the California State University are two highly regarded public university systems based throughout California. But what is the difference between UC and CSU? How are the UC and CSU schools different and how are they alike? In this UC vs CSU guide, we give you a comprehensive comparison of Cal State vs UC and go over what these differences and similarities mean for you and your college choices. First, though, let's take a look at what the UC schools and CSU schools actually are, starting with the UC system. The University of California system is a group of highly prestigious public research universities in California. Established in 1869, UC has grown to include over 280,000 students and 227,000 staff and faculty members. There are 10 campuses, nine of which offer both undergraduate and graduate education: The UC schools are large schools, typically with 20,000 or more undergrads. UCLA has the biggest undergrad enrollment of the UC schools at 32,119, while UC Merced has the smallest enrollment at around 8,000 (it's also the newest of the UC schools, having opened its doors in 2005). As a whole, the UC system offers 160 academic disciplines and 800 degree programs. UC schools are highly regarded and top-ranked. They are extremely competitive to get into and are considered some of the best public universities in the nation. The California State University system is a group of public universities based in California. It is the largest public four-year university system in the US. Even though the CSU schools aren't nearly as competitive as the UC schools, they're still pretty popular because they offer quality academics at an affordable price for California residents. Officially established in 1972, the CSU system comprises 23 schools, which all have undergraduate programs available: In total, approximately 477,000 students attend CSU, where 56,000 faculty and staff are employed. Undergrad enrollment varies tremendously at the CSU schools. CSU Fullerton has the largest enrollment at about 35,401 undergrads, while Cal Maritime has the smallest enrollment at just over 900 undergrads. Additionally, CSU has an incredibly diverse student body, with a high percentage of non-traditional and commuter students, and is known for catering to minority and low-income students. Unlike the UC schools, which focus more on research and academic publishing, CSU focuses more on helping students develop professional, practical skills that will lead them to great jobs right out of college. Here's a side-by-side Cal State vs UC comparison so you can see how the two university systems are both different and alike: Highest: UC Berkeley, UCLA (tie) #20 (Nat'l) Highest: A+ (UCLA, UC Berkeley, UC Irvine) The University of California system is often shortened to "UC," which is why you'll typically see the UC schools referred to as UC Berkeley or UC Irvine, for example, instead of the University of California, Berkeley or the University of California, Irvine (both of which are definitely a mouthful!). That being said, "UC" can also refer to the University of Cincinnati, so be sure to specify which University of California school you're talking about. The California State University system is usually called "CSU" or "Cal State." So the California State University, Fullerton could be called either CSU Fullerton or Cal State Fullerton, for instance. Be aware that "CSU" can refer to several other colleges, too, such as Colorado State University, Chicago State University, and Cleveland State University. There are 10 UC schools (including one graduate-only school in San Francisco) and 23 CSU schools. The UC schools are mostly located in larger cities in either northern or southern California: CSU is a little different. Since there are more CSU schools than there are UC schools, the system is more spread out across the state and has campuses in smaller cities as well as larger cities. This element of convenience makes CSU easier to access for many people throughout California. Both the University of California and the California State University are public state university systems, meaning that they're both funded by the California State government. For more information on how public universities differ from private ones, check out our in-depth guide. CSU is by far the larger of the two systems, both in terms of number of schools and student enrollment. While UC is home to nine undergraduate schools and 290,000+ students, CSU has 23 schools and a whopping 475,000+ students. Regarding undergraduate enrollment specifically, UC currently has 294,662 undergrads while CSU has 477,466 undergrads. However, the individual campuses in the UC and CSU systems vary quite significantly in enrollment. The following chart shows total undergraduate enrollment at UC and CSU schools, from largest undergraduate student body to smallest. All UC schools have been highlighted in green. School Undergrad Enrollment CSU Fullerton 40,087 CSU Long Beach 39,434 CSU Northridge 38,551 San Diego State 35,732 San Jose State 33,848 UC San Diego 33,343 UCLA 32,112 UC Berkeley 31,814 UC Davis 31,657 CSU Sacramento 31,573 UC Irvine 29,449 Cal Poly Pomona 29,103 CSU Los Angeles 27,029 San Francisco State 26,620 Cal State Fresno 24,946 UC Santa Barbara 23,091 UC Riverside 22,868 Cal Poly San Luis Obispo 22,028 CSU San Bernardino 19,182 UC Santa Cruz 17,864 CSU Dominguez Hills 16,916 CSU Chico 15,421 CSU San Marcos 14,503 CSU East Bay 13,499 CSU Bakersfield 10,624 CSU Stanislaus 10,028 UC Merced 8,321 Sonoma State 7,182 CSU Monterey Bay 6,995 CSU Channel Islands 6,437 Humboldt State 5,739 Cal Maritime 880 As you can see, the three largest schools are as follows: And the three smallest schools are as follows: Most UC schools are very large, with around 20,000 to 30,000 students. Meanwhile, the CSU schools have a broader spread of enrollment, with some larger schools (including CSU Fullerton, CSU Long Beach, and San Diego State), some smaller, and many in the medium and medium-large range (about 10,000-20,000 students). Whereas the UC system offers about 900 bachelor's degree programs, the CSU system offers more than 2,700 bachelor's programs. Obviously, what's available at each specific UC and CSU school will vary, so make sure to check ahead of time what majors and minors are offered at the UC and/or CSU schools you're considering. You can look at the list of UC majors by school here, and the list of CSU majors by school here. While both the UC system and CSU system are solid options for college, the UC schools are much more highly ranked and prestigious overall. All UC schools rank in the top 100 national universities on US News. By contrast, most CSU schools rank fairly well, but not amazingly, on the US News Best Regional Universities West list. In addition to US News rankings, we looked at student-produced grades on Niche. Niche grades for UC and CSU schools indicate high to very high student satisfaction at UC, and average to high student satisfaction at CSU. Six UC schools managed to nab an A/A+ rating (UCLA, UC Berkeley, UC Irvine, UC San Diego, UC Davis, and UC Santa Barbara), which no CSU schools were awarded. The highest grade a CSU school earned was an A-, an honor that goes to Cal Poly San Luis Obispo. Overall, the UC schools—being very prestigious and highly ranked—are much more difficult to get into than are the CSU schools, especially UC Berkeley and UCLA, the two highest-ranked schools. In other words, acceptance rates at UC schools are often far lower than those at CSU schools. Here's an overview of the acceptance rates for all UC and CSU schools, from most selective to least. Once again, all UC schools have been highlighted in green for clarity. School Acceptance Rate 11% 15% 29% 29% 33% 34% 38% 47% 49% 59% 59% 61% 66% 73% 73% 79% 82% 84% 85% 85% 87% 90% 91% 91% 91% 93% 93% 93% 94% 94% 94% 97% As you can see here, six of the nine UC schools have acceptance rates around 50% or lower, making them all at least somewhat selective. By contrast, most of the CSU schools are much easier to get into, with many having acceptance rates of 55% or higher. Both UC and CSU have slightly more female-identifying students than they do male-identifying students (as well as a nominal number of unknown or non-binary students). Ethnic demographics differ somewhat, however. At UC, the three largest ethnic/racial groups are Asians/Pacific Islanders (31%), whites (23%), and Hispanics/Latines (22%). At CSU, it's Hispanics (45%) followed by non-Hispanic whites (22%) and Asian Americans (16%). Both university systems have a clear devotion to diversity, but CSU shines a little brighter in its commitment to serving Hispanic/Latinx populations. Currently, 21 out of its 23 schools are Hispanic-Serving Institutions (HSIs). Still, the UC system is making big strides to serve this population, too. At present, five of the 10 UC schools are considered HSIs. One major difference between UC schools and CSU schools is undergraduates' living situations. At most UC schools (besides UC Riverside and UC Irvine), it's very common for undergraduates to live on campus in university housing. At most CSU schools, however, undergraduates commute to campus and do not usually live in university housing (if even offered). There are several advantages when it comes to commuter campuses, such as the option to save money on housing by living at home with your parents and having more flexible class options, which are often given to accommodate older, non-traditional students. Nevertheless, some of the cons of commuting to college include the following: To learn more about commuter campuses, read our in-depth guide. Since both the UC and CSU systems are public university systems, what you pay in tuition and fees will ultimately depend on whether you're a California resident or not. In-state tuition every year is $5,742 at CSU and $13,752 at UC. As you can see, CSU is far cheaper to attend than a UC school—in fact, it's about $8,000 cheaper! When it comes to out-of-state tuition and fees, these figures jump dramatically. At UC, out-of-state students must pay $46,326 per year—over three times higher than what in-state students pay. By contrast, CSU charges tuition differently to out-of-state students, either by the semester unit ($396 each) or by the quarter unit ($264 each). When it comes to Cal State vs UC, which schools should you apply to? Here are four useful tips to help you make your decision. Two big factors for many students are the size and overall location of the school. With UC schools, most are on the larger end in terms of undergrad enrollment (with 20,000-40,000 students), whereas the CSU schools vary significantly, from as few as 1,000 undergrads to as many as 40,000. If you're interested in having a smaller, more intimate student body, first look at the CSU schools before you consider any UC schools. If you'd prefer a more bustling environment, then feel free to look at pretty much all the UC schools (except UC Merced) and about half the CSU schools. In terms of setting, location can vary a lot for both UC and CSU depending on the campus. It might help to remember, though, that UC schools are mostly based in larger cities, whereas CSU schools can be found in smaller cities as well as larger ones. If you plan on commuting to school, keep in mind that larger cities might have worse traffic. Another factor to consider is your academic interests and what you want to major in (if you know). UC and CSU schools don't all offer the same majors and minors, so you'll definitely have to do some research to see what kinds of programs each school offers and whether they have the ones you're interested in. You can do this by using the list of UC majors and the list of CSU majors. For example, a few CSU schools offer majors in apparel/fashion merchandising and management, whereas no UC schools offer any equivalent undergraduate program. You might also want to take into consideration whether your field has a better reputation at UC or CSU. For example, both UC Berkeley and UCLA have premier engineering programs, so you might want to prioritize applying to these schools if you're planning to be an engineering major. UC and CSU differ a lot in what they charge you for tuition and fees each year, so make sure that you're fully aware of what you'll be responsible for paying. Although it's clearly a lot cheaper to attend CSU instead of UC, doing this might mean sacrificing quality of academics and overall prestige for affordability. Remember, too, that you'll need to consider financial aid packages. Despite UC's high cost, 55% of California undergrads at UC pay absolutely nothing in tuition. As for CSU, there are tons of merit-based scholarships you can apply for to try to save some money. Whether you apply to UC schools, CSU schools, or a combination of the two, it'll be a smart idea to look into external scholarships as well. Lastly, you'll need to consider your own academic profile—that is, your GPA and advanced coursework—and see how you compare with real admitted applicants to the UC and/or CSU schools you're looking at. Doing this should help you make an ideal college list that includes a balanced number of safety schools, target schools, and reach schools. For example, if your GPA is about the same as those of admitted students to a particular UC or CSU school, then that institution can be considered a match, or target, school. If your GPA and scores are higher, then that's a safety school, as you're very likely to get accepted. Finally, if your GPA and test scores are significantly lower than the averages at a certain UC or CSU school, then that institution can be considered a reach school, as you're unlikely to get in with your current academic profile (but still could, of course). So when it comes to UC vs CSU, how do these two university systems actually differ? For starters, the University of California is a very renowned public university system known for its world-class research and highly accomplished professors. Meanwhile, as the largest four-year public university system in the US, the California State University is primarily known for its quality academics and affordability. Here are some other key ways these two university systems differ: In the end, to find the right college for you—whether that happens to be a UC school, a CSU school, or something totally different!—you must consider the following four factors: And with that, I say good luck with your UC and CSU applications!
