Common Course Numbering (CCN) System
The Common Course Numbering (CCN) System is a state-mandated initiative aimed at simplifying student transfer and ensuring uniformity in course numbers across California Community Colleges. West Valley College began phasing in courses into this new numbering system beginning Fall 2025.
A Common Course Number is comprised of four elements:
- Subject: 4-letter standardized abbreviation to be used across the state
- Course Type Identifier: All CCN courses are indicated with a “C” prefix before the number
- Course Number: Standardized 4-digit course identification.
- Course Specialty Identifier: System-level suffixes for special courses (e.g. “H” for Honors)
| Course (Prior to Fall 2025) | Common Course Number (As of Fall 2025) |
|---|---|
| COMM 001: Public Speaking | COMM C1000: Introduction to Public Speaking |
| COMM 001H: Honors Public Speaking | COMM C1000H: Introduction to Public Speaking - Honors |
| ENGL 001A: English Composition | ENGL C1000: Academic Reading and Writing |
| ENGL 001C Critical Thinking and Writing | ENGL C1001: Critical Thinking and Writing |
| ENGL 001CH: Honors Critical Thinking and Writing | ENGL C1001H: Critical Thinking and Writing - Honors |
| MATH 010: Elementary Statistics | STAT C1000: Introduction to Statistics |
| MATH 010H: Honors Elementary Statistics | STAT C1000H: Introduction to Statistics - Honors |
| POLI 001: American Government | POLS C1000: American Government & Politics |
| POLI 001H: Honors American Government | POLS C1000H: American Government & Politics - Honors |
| PSYC 001: General Psychology | PSYC C1000: Introduction to Psychology |
The following table provides a crosswalk of courses that are not currently part of Common Course Numbering, but also changed their subject code and/or course number because of CCN implementation.

Yes! Honors courses (with an H) count toward degree requirements and be used in the same way as ENGL C1000.
CCN courses are easy to spot! All CCN courses are indicated with a “C” prefix before the number.
Some subject area codes (like POLI to POLS) were adjusted to match what’s commonly used across California. This makes things clearer and more consistent statewide.

Yes! Courses that haven’t changed will still transfer as usual under existing agreements with CSU, UC, private colleges and HBCUs.
No! MATH 010 = STAT C1000, so your previous course still meets the requirement.
Yes! ENGL C1000 will satisfy the same requirement as ENGL 001A on the AA/AS Graduation Requirements, CSU GE-B, IGETC as well as the upcoming Cal-GETC.
