The Course Identification Numbering System (C-ID) is a statewide numbering system, signaling that participating California community colleges and universities have determined that courses offered by other California community colleges are comparable in content and scope to courses offered on their own campuses. The C-ID numbering system is useful for students attending more than one community college and is applied to many of the transferable courses students need as preparation for transfer. Students should always go to www.assist.org to confirm how each college’s course will be accepted at a particular four-year college or university for transfer credit. Because these course requirements may change and because courses may be modified and qualified for or deleted from the C-ID database, students should always check with a counselor to determine how C-ID designated courses fit into their educational plans for transfer.
