Big changes are taking place with course numbering at California Community Colleges, including Diablo Valley College, and it's all to make transferring smoother.
Making Your Transfer Journey Easier!
Thanks to the Common Course Numbering (CCN) System, courses with the same content will now have the same number across all community colleges. No more guessing if your course will transfer correctly—it's all aligned!
The new numbering system will go into effect for many general education and transfer pathway courses. This includes the following:

The California Community College system is implementing a Common Course Numbering (CCN) system to make transferring easier! Under Assembly Bill 1111 (Berman), courses with the same content will have the same number across all community colleges in the state. This means less confusion, better planning, and a smoother transfer process!
-
If you took courses before Fall 2025, you’ll want to check the new numbers to make sure you’re not accidentally repeating a class you’ve already completed. Stay on top of your academic plan by checking with a counselor if you haven’t done so yet.
-
When colleges make big updates, they roll them out at the start of an academic year. That’s why the first phase of CCN starts in Fall 2025, second phase in Fall 2026—and more updates coming in future semesters.
-
CCN courses are easy to spot! They have a "C" in the catalog number (e.g., ENGL-122 is now ENGL-C1000).
-
Some subject area codes (like POLSC 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 and private colleges.

-
Classes completed Summer 2025 or earlier will not be changed on your official DVC transcript. The former course title, subject, and number will remain. Starting Fall 2025, CCN will go into effect and completion of any of the CCN courses will be reflected on transcripts using the new course title, subject, and number. All common course numbering courses will start with a "C" in the course number.
-
No! Math-142 equals STAT-C1000, so your previous course still meets the requirement.
-
Yes! POLS-C1000 is the same course as POLSC-120, so your new passing grade will count.
-
Yes! Honors courses (with an H) still count toward degree requirements.
