Masks – Masking in all indoor settings, with the exception of instructional spaces or environments where it is otherwise explicitly indicated, is voluntary. Masks may be temporarily removed in classroom settings when a student is called upon by their instructor or when they wish to offer comments or ask questions. This is up to the discretion of the instructor.

From December 24, 2022, through January 2, 2023, the campus will be closed. For graduate students living in residence on campus, we ask that you please complete the online Graduate Winter Break Housing form and identify the days you will be staying in Caltech Housing. Undergraduate students should pick up an Institute-provided COVID-19 at-home antigen test before departing from campus. The Institute is requiring that all students test before they travel back to campus for the start of the winter term. More information and details about testing protocol are available in the updates sent to graduate students and undergraduate students.
