Yes! The Milestone Class Dinners are open to all alumni who want to celebrate with friends and fellow Techers—your graduation year doesn’t have to end in 1 or 6. 

Registration is open through May 1, 2026. Visit the registration page for more information. 

The $100 registration fee per person ($75 for GOLD) includes admission to special House Happy Hours, dinner at the Athenaeum, and a gift from the Caltech Alumni Association.

The Caltech Alumni Association (CAA) and Caltech Alumni Relations are proud to offset event costs to provide a ticket price accessible to as many Techers as possible compared to peer institutions.

Milestone Class Dinners for classes ending in 1 and 6 will join the spring 2026 schedule, alongside Seminar Day and Half Century Club weekend. This offers an opportunity for alumni to add more to their milestone class celebration with faculty sessions, campus events, and more Techers on campus to celebrate with. 

Alumni Weekend continues in October as an annual gathering for alumni of all class years, featuring the Distinguished Alumni Awards, division speakers, House activities, Athletics Hall of Honor, SURF Seminar Day, Graduates of the Last Decade events, and more. 

Both! Half Century Club honors all alumni who graduated 50+ years ago, while Milestone Dinners celebrate specific reunion classes. If you’re in the Class of 1976, you’ll be inducted into Half Century Club and recognized at the Milestone Dinner. Your Half Century Club ticket includes admission to both. Similarly, if you’re in the Class of 1966 or 1961, for example, you will also be celebrating at both events on Friday, May 15! The events complement each other throughout the weekend. 

Please be mindful that most events are geared for an adult audience (i.e., alcohol served, lectures) but are fine for children to attend with their parent/guardian. No childcare will be available. Registration is required for guests of all ages in order to participate in alumni events as part of Milestone Class Dinners.
