Introduction
The California Institute of Technology (Caltech) is one of the most prestigious science and engineering institutions in the world. Known for its extremely selective admissions and research-driven education model, Caltech offers a limited but highly specialized set of master’s and graduate-level programs.
Unlike many large universities, Caltech does not operate a broad, standalone master’s system. Instead, most graduate students are admitted into PhD programs, with a master’s degree often awarded along the way. This makes understanding Caltech master’s degree programs especially important for international students and applicants aiming for advanced study in engineering, physics, computer science, and related fields.
This guide covers everything you need to know about Caltech master’s degrees, including programs, admissions, costs, requirements, and career outcomes.
Does Caltech Offer Master’s Degrees?
Caltech is unique compared to many universities in the United States.
Key Fact:
Most Caltech graduate students are admitted directly into PhD programs, and a master’s degree (MS) is often awarded as part of the PhD pathway.
Important Points:
- Caltech does NOT heavily emphasize standalone professional master’s programs
- Most MS degrees are earned “en route” to a PhD
- Some divisions offer limited terminal master’s options
- Research-focused structure dominates graduate education
This means students applying for a Caltech master’s degree are often applying to a PhD track first.
