Yes, Course Finder is available to all current and prospective students of California public higher education systems (UC, CSU, CCC). Just select the "I don't have a primary California college" radio button when searching. The selection of a home college only affects the sorting and the equivalence to local classes. Students are then able to apply directly to any college where they find a class they wish to take.
Cross-Enrollment/Instant Enrollment: Some colleges offer immediate enrollment into their courses if users are current students at another California Community College. While any user can always apply directly to a college to take a class, Instant Cross-Enrollment allows students to register for a class immediately, take the class through their home college Canvas, and then have their transcript transferred back to their home college automatically. Cross-enrollment does requires a valid student login at a Home College.
To search for colleges within the California Community College system, please visit the Chancellor's Office website.
