Common Course Numbering
Same Course Number. Every Community College.
Introducing the new Common Course Numbering (CCN) system
Planning to transfer? Want to make sure you don’t accidentally repeat the same course at another California Community College?
Good news! California’s Community Colleges are rolling out a new system called Common Course Numbering (CCN) to make it easier for students like you.
Through CCN, equivalent courses across all California Community Colleges will share the same title, subject, and course number — no matter which college you attend. This new system makes it easier to identify transferable courses, reduces confusion and provides a smoother educational journey for you.

The new Common Course Numbering (CCN) system is designed to make your college experience smoother, especially if you plan to transfer or take classes at more than one college. How it helps:
-
Clearer Course Matching
Whether you’re at Chaffey College or another California Community College, the course titles and numbering will be consistent. That makes it easier to know exactly what you’re signing up for — and how it fits into your academic plan.
-
Streamlined Transfer Process
With consistent courses across all California Community Colleges, it's easier to plan your transfer path with confidence. You’ll know which classes meet requirements — whether you're staying at Chaffey College, transferring to another college, or heading to a CSU or UC — without second-guessing if they’ll count.
-
Save Time and Money
By clearly showing which courses are equivalent, CCN helps you avoid retaking the same class or enrolling in courses that don’t move you forward. That means fewer delays, fewer unnecessary units, and more progress toward your degree or transfer goals.
What’s Changing
The following course numbers and titles at Chaffey College have changed to align with the CCN system.

FREQUENTLY ASKED QUESTIONS
Classes completed Summer 2025 or earlier will not be changed on your official Chaffey College transcript. The former course title, subject and number will remain the same. Starting Fall 2025, CCN went into effect and completion of any of the CCN courses will be reflected on transcripts using the new course title, subject and number from that semester onward. All common course numbering courses will start with a "C" in the course number.
Courses identified as common between California Community Colleges will begin with a “C” in the course number (e.g., ENGL C1000).
No. Courses you’ve already passed will still count.
No — this is happening across all California Community Colleges. The goal is to unify course numbers statewide.
Yes. Courses that have not been changed may continue to transfer under previously agreed-upon transfer agreements between two-year colleges and four-year colleges.
Yes! The goal is to have all transfer level courses adopted the CCN system over the next couple years, and possibly more beyond that.
If you are currently enrolled, completed courses will still fulfill your requirements, even if their course numbers change. However, you will see updated course numbers when planning for future semesters. For instance, if you had PSYCH-1 planned for a future term in your educational plan in Fall 2025, that course was updated to PSYC C1000.
