9/29/22 - Notice from the CCCTC about Finalized Descriptors and Courses

Update -The fix to restore decriptors status was released 9/26/22 and the majoirty of courses should now be visible in the articulation officer course list and on the public courses page. We are reaching out to AO's directly to verify the course list and provide support with course visibility as needed. Thank you for your patience and support as we worked to address this issue.


Welcome to C-ID.net, the website for the Course Identification Numbering System (C-ID).


C-ID is a supranumbering system being developed to ease transfer and articulation in California’s higher education institutions. To learn more about C-ID, please visit our ABOUT US page. To access FAQs for faculty and articulation officers, please click here.

Currently, C-ID has 368 approved descriptors and 33 draft descriptors from over 81 different disciplines. To view C-ID’s finalized Descriptors, or to review Draft Descriptors, please visit the DESCRIPTORS page. Once there, you can select finalized descriptors from a drop-down menu. The Draft Descriptors Review and Comment Area can be accessed by clicking on the View Draft Descriptors link on the Descriptors page.

To access the CSU courses that have been identified by campuses as comparable to C-ID descriptors, use the COURSES tab or https://c-id.net/courses. You can search for courses by discipline or CSU campus.
