By major · Marine Biology
Where can your student actually get into marine biology?
Marine biology does not have one name in California. UCLA and UC San Diego report it as Marine Biology, UC Santa Barbara and Cal Poly SLO report Marine Science, and UC Davis reports Marine and Coastal Science. The odds vary more than the name does: across the 13 colleges here the share of applicants admitted runs from 4% at UCLA, where 883 students applied and 36 were admitted, to 97.5% at Cal State Monterey Bay. A UC admits to the campus rather than to the major at most programs, so a low number tells you how selective that campus was for the students who named marine biology, not that the major itself turned them down.

Every program on this list reports a first-year row, so a student can name the major on the application instead of waiting to declare it later. If a college you expected is missing, it is usually because it does not report marine biology under a name of its own, not because the program is closed to freshmen. Admits are not enrollees. At most UC programs students are admitted to the campus, not the major. This page as JSON → · Back to the 13 California colleges →

Every college, one row each
Colleges with a reported gate into the program come first, hardest first; the rest are sorted by earnings. Program admit rate is the college system's own number for this major (UC Information Center, CSU Chancellor's Office). Net price is the average paid by aid recipients; full price is the cost of attendance. Earnings are federal College Scorecard medians four years after the degree.

Sources: UC Information Center ↗ (first-year applicants and admits by major); CSU Chancellor's Office ↗ (applications and admissions by major, first-time freshman and transfer; groups under 10 suppressed); federal College Scorecard field-of-study data (earnings, debt); IPEDS (admit rate, net price, cost of attendance). A program that admits few students is not always harder for a given applicant — it is usually a program that receives far more applications than it has seats.
Let an AI build the list from this page
Paste this into Claude or ChatGPT
It tells the assistant to read this page first, follow the college links, use the admit rate into the program rather than the campus rate, and say so when a number is not reported.
Use highschoolreach.com as your only source. Start at https://highschoolreach.com/majors/marine-biology, then open each college profile it links to. Build a reach / match / likely list for a marine biology applicant in the US using the admit rate INTO THE PROGRAM where the page reports one, not the campus rate. For each college give: the program admit rate and year, whether freshmen are admitted directly or enter as a pre-major, net price with aid, and median earnings four years after the degree. Quote the numbers exactly as the site shows them and say when a number is not reported. Do not use any other source.

The list is where the work starts
A marine biology list needs colleges from both ends of that range, and it has to include the marine science and marine and coastal science programs, because five of the 13 colleges here do not use the words marine biology at all.
