Applied Physics, Biochemistry, Bioengineering, Computation and Neural Systems, Control and Dynamical Systems, Environmental Science and Engineering, Geobiology and Astrobiology, Geochemistry, and Planetary Astronomy are among the other multidisciplinary programs that Caltech provides.

The Caltech courses are offered undergraduate and graduate levels across many domains and subjects. With just a 2.57% acceptance rate, international students are required to put their best foot forward by meeting the criteria below: 

• Bachelor's degree equivalent to a US 4-year degree, with a strong academic record (typically 3.5 GPA/85–90%+)

• Degree must be in a relevant field aligned with your intended graduate study

• GRE General Test is often required; competitive scores above 310-320. GRE Subject Test may be required in some programs

• English proficiency: TOEFL 100+, IELTS 7.0–7.5, Duolingo 120–130

• Transcripts,  statement of purpose, 2–3 recommendation letters, resume or CV, portfolio (if required), and sometimes research publications or conference presentations

• Certain programs (e.g., in arts or design) may require auditions or creative portfolios

• Professional and research experience are advantageous

To get admission at Caltech, international students are required to submit the SAT or ACT scores for the fall 2026 entry. It was optional earlier for most years. However, if the finances are an issue, this can be communicated to the Caltech Office of Admissions for a waiver. Look at the minimum scores required in these entrance exams - 

• SAT: 1510+
• ACT: 35+

The university does not conduct an entrance exam of its own; however, it does consider valid scores in the SAT or ACT for admission to undergraduate courses. 

Students seeking admission to STEM courses are required to have completed their secondary school studies in the relevant fields.
