Common Course Numbering
To simplify credit transfer between institutions, California Community Colleges have adopted a statewide numbering system through the Common Course Numbering system (AB 1111). This system will eventually provide a standardized set of subjects and course numbers across all California Community Colleges, ensuring that equivalent courses have the same identifier, regardless of the college offering them. By aligning course numbers, students can more easily identify transferable credits, reducing confusion and streamlining their educational pathways.
The Common Course Numbering system helps students plan their academic journeys with confidence, particularly when transferring to the University of California (UC) and California State University (CSU) systems. This initiative supports seamless articulation agreements and reinforces consistency across the state's diverse community colleges.
Implementing Common Course Numbering
San Diego City, Mesa and Miramar Colleges will begin rolling out the new course numbering system in a series of phases. The first phase begins Fall 2025 where the following courses will be affected:
CCN Lookup
Old Course | New Course | Effective |
---|
What Does This Mean?
In Summer 2025, if you're interested in enrolling in MATH 119 - Elementary Statistics, you will look up MATH 119 as usual. However, if you're looking for that course in Fall 2025, you will need to look for STAT C1000 instead.
What will appear on mySDCCD and my transcript?
Students will see the old course for any classes taken during or before Summer 2025. On or after Fall 2025, students will see the new common course numbering system. All common course numbering courses will start with a "C" in the catalog number:
STAT C1000
Subject Catalog Number
The California Community College system is implementing a student-facing Common Course Numbering (CCN) system, as required by Education Code Sections 66725-66725.5 through Assembly Bill No. 1111 (Berman), to be completed by July 1, 2027. This system will create common course numbers for comparable courses across all community colleges in the state, facilitating smoother transfers to four-year institutions and reducing unnecessary credit accumulation. By maximizing credit mobility, the CCN system will enhance equitable transfer opportunities and support student success by helping students build cohesive academic plans, understand course transferability, and make informed course selections. This collaborative effort involves faculty, administrators, staff, and system officials to ensure the best outcomes for California community college students. (Source: ASCCC)
It is important to you if you have taken courses at any California Community College prior to Fall 2025 because course numbers and titles have changed and you do not want to accidentally repeat the same course.
When colleges update courses, they do it during an academic year. Fall 2025 is part of the 2025-2026 academic year. So each phase will roll out courses during the fall semesters.
Courses identified as common between California Community Colleges are denoted with a "C" in the catalog number of the course (e.g. ENGL 101 is now ENGL C1000)
Some subject area prefixes have been changed to align with what is common throughout the state (e.g. POLI is now POLS)
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.
Background on the Common Course Numbering project is available at the website of the California Community College Chancellor's Office.
No, you do not need to submit a modification of major. MATH 119 is equivalent to STAT C1000, so STAT C1000 will automatically count toward your degree requirement in place of MATH 119.
No, you do not need to enroll in STAT C1000. MATH 119 is equivalent to STAT C1000, so MATH 119 will fulfill your certificate or degree requirements in place of STAT C1000.
