California Institute of Technology

Admission to the California Institute of Technology is among the most competitive in higher education, and the school continues to hold a powerful draw over the students it accepts. In the 2027 U.S. News rankings, Caltech placed 5th nationally, strengthening its position from 10th in 2018. For the 2025 admissions cycle, the acceptance rate fell to 2.6%, which was lower than all peer schools in its comparison group of 30 private research universities with similar ranks. Admitted applicants demonstrate strong commitment to enrolling; Caltech's yield rate reached 61.2%, which was higher than 60% of peer schools in that comparison group. With selectivity at this extreme level, prospective applicants must recognize that Caltech operates with almost no margin for error in undergraduate admissions.

The California Institute of Technology has an admission test policy under which scores are not considered, meaning tests are test-blind and results are not used even if submitted. In 2021, 45% of students submitted SAT scores and 34% submitted ACT scores. For families evaluating what grades and scores successful candidates present, applicant cases collected by Forward Pathway—which are unofficial records rather than university statistics—show that admitted international applicants achieved a median unweighted GPA of 3.98 and a median SAT score of 1545. Denied applicants in that sample had lower academic metrics. Because test scores are completely excluded from admissions decisions, applicants need to demonstrate their academic strength through near-flawless grades in demanding mathematics and science coursework, competitive STEM competition experiences, and deep intellectual curiosity.

Academic concentrations at the California Institute of Technology are heavily focused on technical fields, where its largest degree tracks align closely with its highest national reputations. Undergraduate majors show considerable concentration, with the top three programs accounting for 59.6% of all bachelor's degrees conferred in 2025. Computer Science is by far the largest undergraduate major, graduating 88 students, followed by Mechanical Engineering and General Physics. In the 2026 U.S. News graduate rankings, Caltech earned 1st place in Physics, Chemistry, and Earth Sciences, while Mechanical Engineering placed 3rd. Bachelor's graduates in Computer Science achieved immediate financial returns, earning median starting pay of $160,167 one year after graduation according to 2023 data. For prospective applicants, Caltech functions as a specialized powerhouse where resources and enrollment converge around premier engineering and physical science programs.

The California Institute of Technology operates as an intimate university where graduate researchers outnumber undergraduates. In 2025, Asian students formed the largest undergraduate demographic, accounting for 90 first-year students, or 41.3% of incoming freshmen. International students also maintain an extensive footprint across the institution, representing 671 graduate scholars, or 46.5% of all graduate students. Domestic White, Hispanic, and multiracial students make up the rest of the campus. These demographics reflect an academic environment centered heavily on post-baccalaureate scientific training, where undergraduates share laboratories and facilities with a substantial cohort of global graduate researchers.

Undergraduate life at the California Institute of Technology is dominated by students of traditional college age who enter directly after secondary school. In 2025, students aged 20 to 21 accounted for 45.2% of the undergraduate body, while those aged 18 to 19 made up 43.1%, leaving only a small fraction of older undergraduates. Conversely, the graduate population presents a mature research demographic, with 54% of graduate students aged 25 to 29 and another 34% aged 22 to 24. This sharp age separation between divisions means residential campus activities revolve around a young, tightly focused undergraduate group, while academic laboratories and research centers reflect the professional routines of older doctoral and master's candidates.

The international presence at the California Institute of Technology has expanded steadily, though global enrollment remains much heavier at advanced degree levels. Between 2016 and 2025, the undergraduate international share climbed to 14.1%, rising above earlier enrollment levels. Over the same span, the graduate international proportion increased to 46.5%. Graduation figures from 2025 show that international representation concentrates primarily in post-baccalaureate programs, with international students earning 10% of bachelor's degrees compared to 60.1% of master's degrees. At the master's level, international graduates concentrated heavily in technical disciplines such as Bioengineering and Biomedical Engineering, General Physics, and Electrical and Electronics Engineering, while undergraduate international recipients were most prevalent in General Physics and Computer Science.

Applicants exploring higher education options around Pasadena and the broader Los Angeles metropolitan area can consider several distinguished institutions close to Caltech. Just 4.9 kilometers away is Occidental College, a liberal arts college holding the 38th spot in its category in the 2027 rankings. Moving toward central Los Angeles, University of Southern California is located 12.1 kilometers away, ranked 27th among national universities, while University of California-Los Angeles sits 18.7 kilometers away, holding the 20th position. Toward the east in Claremont, Pomona College is located 23.7 kilometers from campus and stands at 3rd among national liberal arts colleges. These nearby institutions offer families a selection of prominent private research universities, major public institutions, and selective liberal arts colleges within a short radius.

Campus safety records at the California Institute of Technology indicate that institutional disciplinary referrals account for the bulk of reported incidents. In 2025, the campus crime rate per 1,000 students stood at 20.4. Across the three-year reporting period from 2023 to 2025, alcohol-related disciplinary referrals represented the primary violation category by a substantial margin, totaling 335 incidents, with minor numbers of drug disciplinary citations. Offenses involving property and personal safety occurred at much lower frequencies over the same 2023 to 2025 period, topped by 39 motor vehicle thefts, followed by smaller totals for sexual harassment, stalking, and burglary. These records demonstrate that safety management on campus centers predominantly on student conduct and alcohol enforcement rather than widespread violent crime.
