Welcome FROM THE Caltech Y

The Caltech Y, a student driven organization affiliated with Caltech, was founded in 1916 as a student chapter of the YMCA, to provide programs planned by, and for, students… and to promote leadership development and self-discovery. While the Caltech Y is now a separate non-profit with a staff and a board of directors, the spirit of our founding remains – student led opportunities that enrich student life and challenge students to be engaged citizens of the world.

All Y programs encourage students to become active participants at Caltech and engaged citizens of the world. Leadership opportunities are available for students who wish to play an active role on campus either through coordinating volunteer projects, planning outdoor trips, inviting speakers, or serving on the ExComm, the Y's student governing board.

Overview of Y Programs and Opportunities


Caltech students have a long history of responding to social issues and global concerns. The Y recognizes the need for meaningful discourse on topical issues through the Social Activism Speaker Series, featuring thought-provoking speakers. Throughout the years, the Y has been on the forefront of social issues, always helping students broaden their horizons. We continue to sponsor engaging programs with WorldFest, the DC Science Policy Trip, India Cultural Trip, and the Advocating Change Together (ACT) Award.



In order to broaden your Caltech experience, the Y hosts a variety of fun social activities. From movie nights to Explore LA, the Caltech Y knows the importance of fun outside the classroom. If outdoor adventure is your interest, check out all the Y has to offer. Explore a new adventure trail or National Park on one of many Y led outdoor trips throughout the year. Sign up for the ultimate kick-off to your Caltech experience: The Y-Hike to the California Sierras. The Y-Hike, our annual outdoor pre-orientation trip, is a great way to meet new students in a relaxed setting and have a great time in the outdoors. The Y-Hike is the week before New Student Orientation. Open to all new students regardless of ability. Look for an email announcement in July or check our web site for more information.


In response to COVID-19, we’ve gone virtual!  Until we can safely gather, students can remotely volunteer to tutor 6-12 grade students, serve their community through Make-A-Difference (MAD) Weeks, join thought-provoking talks through the Student Activism Speaker Series, contribute to the Caltech COVID Cookbook, relax through online meditation classes, among others.  Even in this uncertain situation, we have created opportunities for students to make a difference and share their time and interests with our community.


For a full listing of all we have to offer including discount tickets sales, outdoor and AV equipment rentals, access to the Y lounge and more, go here.

On any given week during the school year, Caltech students volunteer their time and effort to those in need. The Y coordinates many of these efforts, matching students with community agencies where their skills can be best utilized.

The largest of our service efforts are the Rise Tutoring Program, Alternative Spring Break (ASB), Make-A-Difference (MAD) Day and our ongoing volunteer opportunities at Union Station Homeless Shelter, Hathaway Sycamores Learning Center, and local Pasadena schools. Tutoring middle and high school students through the Rise Program is a great way to get involved. ASB is a chance for you to get away during Spring Break and help others while you travel. Past sites have included Mexico, Catalina and San Francisco. MAD Day is a local volunteer effort where the Caltech community comes together to help community organizations and families. Everyone who participates has a great time during this one-day event in spring. Check our web site for a full listing of volunteer opportunities.
