University of California, Santa Barbara vs. University of California, Santa Cruz

UCSB is the tougher admit by a wide margin. It takes about 38.2% of applicants against roughly 72.7% at UC Santa Cruz, one of the more accessible UC campuses, and it draws a bigger pool too (around 110,000 first-year applications to UCSC's roughly 66,000). Both campuses read test-blind, so neither weighs the SAT or ACT, and out-of-state and international applicants face longer odds at either, making up only about 15% of UCSB undergraduates and 5% of UCSC's.

UC Santa Cruz puts more of its degrees into computing. Computer and information sciences rank as its single most popular named field at about 17%, sitting on a deep sciences base that leads the campus overall at 23%. UCSB grants only about 7% of degrees across engineering and computing combined, leading instead with the social sciences at 27% and the sciences and mathematics at 23%. A computing-forward undergraduate will find the heavier concentration at UCSC, while UCSB fits someone who wants CS inside a more social-sciences-led university.

On cost, UCSC carries the lower out-of-state sticker, about $54,105 in tuition and fees against $56,913 at UCSB, and it meets slightly more demonstrated need (roughly 86% on average to UCSB's 82%). More UCSC first-years receive need-based aid as well, about 49% versus 44% at UCSB, though UCSB's average package runs higher at roughly $35,891 to UCSC's $31,542. California residents see the two land close together, near $16,503 in-state at UCSC and $17,643 at UCSB. UCSC's cost figures come from its most recently published 2024–2025 Common Data Set.

Enrolling about 23,091 undergraduates to UC Santa Cruz's 18,194, UCSB is the larger campus. It teaches at a somewhat lower student-faculty ratio too, 18:1 against UCSC's 22:1. Nearly all undergraduates live on campus at both, but the structure splits: Santa Cruz builds campus life around a system of small residential colleges, while UCSB runs a more conventional large-campus model on its coastal bluff.

Setting separates these two most clearly. UCSB occupies a Pacific Ocean bluff near Goleta, with a beach-town feel and the social sciences as its most-conferred field. UC Santa Cruz climbs through a redwood forest above Monterey Bay, divides its undergraduates among small residential colleges, and keeps an independent streak you can read in its Banana Slug mascot. UCSC also runs a modest Greek scene, with about 3% of men in fraternities and 6% of women in sororities. Both keep most students on campus, so the environment around each campus carries the contrast.

Graduating more of its students, UCSB pulls ahead on outcomes. Its six-year graduation rate sits near 84% against 74% at UC Santa Cruz, and it holds 93% of first-years into the second year to UCSC's 90%. Both keep the large majority of who enrolls, though UCSB's retention and completion run a few points ahead across the board.
