Simplifying Course Transfers

Starting in Fall 2025, California community colleges are adopting a Common Course Numbering (CCN) system (per AB 1111). This system assigns common course numbers for comparable courses across all community colleges in the state. The goal of CCN is to facilitate a smoother transfer of credits between colleges and four-year institutions. CCN uses the following structure:

Subject Code/Course Prefix
Four-letter abbreviation of the subject area (for example, ENGL for English).
Course Type Identifier
CCN courses begin with "C" but local courses do not (for example, C1000 vs. 300).
Course Number
Standardized 4-digit number (for example, C1000 vs. 300).
Course Speciality Identifier
Some courses have additional characters appended to their course number, such as:
  • E = Embedded support
  • H = Honors course
  • L = Lab-only course
  • S = Support Course

As an example, ENGWR 300 becomes ENGL C1000 after the CCN transition.

How Common Course Numbering Helps Students

The new system helps you plan your classes better, especially if you want to transfer to a University of California (UC) or California State University (CSU). It makes transferring credits simpler and clearer for everyone.

What This Means for Students

  • Summer 2025: The current numbering system remains in place. For example, if you want to take ENGWR 300, you will look for ENGWR 300 when you register for classes.
  • Fall 2025: Some courses will transition to CCN. For example, ENGWR 300 is included in the first transition phase, so you will look for ENGL C1000 when you register for Fall 2025 classes.
  • Phased Transition: The transition will happen in phases, so you'll see both types of courses in the class schedule.
