AB 1111 - Common Course Numbering System

What is AB 1111?

AB 1111 is a California law designed to simplify course navigation across the California Community Colleges (CCC) system. It requires all CCC to adopt a Common Course Numbering (CCN) system for general education and transfer pathway courses. This ensures that comparable courses have the same course numbers at every CCC statewide.

When does this take effect?

Beginning in the 2025–26 academic year, colleges began transitioning select courses to the CCN system. This is an ongoing, multi-year process that will continue over several academic years.

Why is this important?

AB 1111 reduces confusion, streamlines degree completion, and supports a smoother transfer process, helping students save time and stay on track. If you have questions about how AB 1111 and the CCN system impact your educational plan, consult with a counselor for personalized guidance.

Additional Common Course Numbering (CCN) System Information

The CCN system, established under AB 1111, standardizes course numbering across California Community Colleges to support transfer and degree completion. 

The CCN system will use the following structure: 

  • Subject: Four letter abbreviation (e.g., STAT for Statistics)
  • Course Type Identifier: C= Common Course Number; local courses would not have a C
  • Course Number: Standardized 4-digit course identification

"C1000-C1999 = 100 level courses"

"C2000-C2999 = 200 level courses"

Courses identified as common will feature a "C" in their catalog numbers (e.g., ENGL 001A has become ENGL C1000) at all CCC. Some subject area prefixes will also change to align with statewide standards (e.g., POLSC has become POLS). Revisions, including new course numbers and subject prefixes, will be clearly indicated in the college catalog  and class schedules to help students easily identify and navigate these changes.
