Discover the STEM pioneer in you

Caltech's bold, trailblazing science has led to such important discoveries as antimatter, the nature of the chemical bond, quarks, the foundations of molecular biology, and the RDA. Through access to a vast array of resources, a community of intellectual equals, and an environment that promotes collaboration and cooperation over competition, Caltech challenges, encourages, and nurtures our students to become some of society's most innovative thinkers, leaders, and doers.

At Caltech, 961 undergraduates, over 1,200 graduate students, more than 320 professorial faculty, and over 600 research scholars investigate and design solutions to address the most challenging problems confronting society today. Students enjoy virtually unlimited research opportunities and close interaction with professors. With our 3:1 student-to-faculty ratio, opportunities abound to interact one-on-one with Caltech's scientists and engineers, who are pursuing world-changing research.

Academic Programs

Caltech offers students a robust yet challenging learning and research environment that promotes communication, collaboration, exploration, teamwork, integrity, personal growth, and respect for others. You'll start your Caltech education with our core curriculum to ensure that you have a strong base in mathematics and the natural sciences. You may decide to take a freshman seminar or two to check out the latest research in different fields.

Toward the end of your freshman year, you'll choose an option (what other schools consider a major). Early on, our undergraduates build respect and appreciation for learning from one another, for creative problem solving, and for applying a broad understanding of the basic sciences to a variety of fields.

Residential Life 

Undergraduate life, both academic and social, revolves around the eight student "Houses" and The Bechtel Residence which are "self-governing living groups." Caltech's residential system bring students from all class years and backgrounds together under one roof and elevates collegiate housing way beyond the standard residential hall. It provides you with your first set of friends as a student, which can be one of the most daunting aspects of going to college. The social and academic support from residential system transforms your peers at Caltech into a second family. Seven of the houses are exclusively for undergraduates, with the eighth house welcoming a blend of undergrads, graduate students, and faculty-in-residence. The Bechtel Residence is a new space for 212 undergraduates as of the fall 2018. Learn more about residential life.

Extracurricular Life

Deepen your talents and interests and build lifelong memories by participating in one of Caltech's organized athletic programs, its student-run clubs, or its many performing arts organizations (music or theater). You can also discover a variety of cultural and awareness events, diversity workshops, and support groups through the Caltech Center for Diversity. The Caltech Y offers opportunities for community service, outdoor adventures, and more. There is plenty to explore beyond the labs at Caltech! Learn more about Student Life.
