    From Mt. SAC’s academic calendar. Short-term and late-start classes have their own deadlines, listed with each class in the schedule.

    Does Mt. SAC have a winter session?

    Yes. Mt. SAC’s winter 2027 session runs Jan 4 – Feb 14. A winter class is a full course squeezed into a few weeks, so it can take a requirement off a heavy spring, at the cost of a fast pace.

    Mt. SAC’s calendar calls it: “Classes Start”.

    Questions students ask

    When can I sign up for spring 2027 classes at Mt. SAC?

    Priority groups and continuing students: Thursday, November 12, 2026. Your exact time is the registration appointment shown in Mt. SAC’s student portal.

    Why do some students get to register before me?

    California's community colleges follow a registration order set by state rules (California Code of Regulations, Title 5, section 58108). Groups the law names come first, including active-duty military and veterans, current and former foster youth, and students in DSPS, EOPS or CalWORKs. Next are continuing students who have finished orientation, placement and an education plan with a counselor. Mt. SAC sets the exact order within those rules.

    How do I get an earlier registration time at Mt. SAC?

    Finish orientation, placement and an education plan with a counselor at Mt. SAC before registration opens, and stay in good academic standing. Students can lose priority after two terms in a row on academic or progress probation (some colleges now call it "notice"), or once they pass 100 degree-applicable units.

    What if the class I need is full?

    Join the waitlist if the section has one, and keep an eye on it through the first week: seats open up as students drop. Depending on the college, you are either added automatically or sent a permission number or add code that expires, so check your email. Going to the first class meeting matters, since instructors often add waitlisted students who show up. The list above shows which Mt. SAC classes filled last fall, so pick backups for those.

    When does the spring semester start at Mt. SAC?

    Spring 2027 classes at Mt. SAC start Monday, February 22, 2027.

    Can I take winter classes at Mt. SAC?

    Yes. Mt. SAC’s winter 2027 session runs Jan 4 – Feb 14. Winter classes count the same as spring ones, but cover a full course in a few weeks.
