Science Education, Communication, or Policy
UCSC’s proximity to Silicon Valley and initiatives through the Silicon Valley Campus further broaden graduate and career options in entrepreneurship and technology.
UC Santa Cruz is fully test-free: SAT/ACT scores are never used in admissions decisions and serve only for placement or course credit if submitted.Applicants from international or national board systems (e.g., CBSE, ISC, IB) may apply without standardized tests; transcripts and board exam results are evaluated holistically.English proficiency tests (TOEFL, IELTS, Duolingo, PTE) are required only if secondary instruction was not in English; common minimum thresholds are TOEFL iBT 79–80, IELTS 6.5, or Duolingo 115+. Waived if SAT/ACT English section meets requirements.Letters of Recommendation are not required for general admission, nor for the Astrophysics program.Prospective undergraduates apply via the UC application (Common App not used), which includes no major-specific supplemental essays; only four general Personal Insight questions (~350 words each).Interviews are not offered or required for admissions.Recommended high school coursework: four years of English, at least three years of math including calculus, three years of lab science (especially physics), social studies, and world language. Prior astronomy coursework not required.Students pursuing the B.S. in Physics (Astrophysics) begin with technical prerequisites like calculus-based physics (PHYS 5A/B/C), Math 19A/19B/23A, and introductory physics; a strong foundation in calculus and physics is expected. AP scores (calculus or physics) may count toward prerequisites.Major declaration requirements: Must earn a cumulative GPA ≥ 2.70 in PHYS 5A, 5B, and 5C (or equivalents); if GPA is 2.66–2.69 stricter conditions apply (e.g. B in PHYS 5D) for eligibility. All qualification courses must be taken for a letter grade; repeated low grades may render a student ineligible to declare.Upper-division electives required: Astrophysics majors take specialized lab or theory electives within the Physics department, rather than standard physics labs. These electives are available to other majors too and reflect UCSC’s combined Physics/Astronomy program approach.Research involvement: Undergraduate astrophysics students are strongly encouraged to participate in research projects with faculty in Astronomy & Astrophysics; opportunities include early-entry research courses like ASTRO 9 and summer research.Transfer screening requirements: Transfer students must complete equivalencies to the UCSC major qualification courses—three quarters of calculus-based physics with labs and three quarters of calculus. Additional math (linear algebra, vector calculus, differential equations) and modern physics coursework highly desirable.Degree requirements: UCSC requires at least 120 quarter credits, including at least 42 upper‑division credits, a minimum 2.0 overall GPA, and must meet college-level writing proficiency (ELWR).Research Assistant – supports astrophysics research in labs or observatoriesData Analyst – analyzes scientific data for research or industrySoftware Developer – builds tools for simulations or data processingPlanetarium Educator – presents astronomy content to public audiencesObservatory Technician – maintains and operates telescope systemsHigh School Physics Teacher – teaches physics and basic astronomyAerospace Technician – assists in spacecraft testing and designScience Communicator – explains space science through media or outreachSatellite Operations Analyst – monitors and manages satellite functionsGraduate Student – continues academic study toward research or teaching
